ABSTRACT
Nowadays, health monitoring is crucial, especially monitoring the temperature and heartbeat of the patient in Covid / non-Covid situations. Continued monitoring of the patient is not a possible and tedious job. IoT plays a critical role in Hospitals where patients are in Intensive Care Units (ICU), and patients are treated at home (isolation points). The devices receive data continuously and monitor by the doctors remotely. This paper presents temperature and heartbeat monitoring using Internet Of Things (IoT) devices with an algorithm to capture data from devices and sends it to computer devices at a reasonable cost. Proof Of Concept has been created with the help of an Arduino board, Pulse Sensor, Temperature Sensor, Breadboard, ESP8266 Wi-Fi module, and Liquid Crystal Display (LCD). The IoT devices capture data from different devices (patient health data) in real time. The Health Care Monitoring (HCM) Application builds using microservices architecture, runs on top of the Thingspeak data, and sends notifications to the doctors if there is an emergency. The doctors can act according to rather than monitor continuously. This model eliminates manual intervention for taking the reading from time to time. © 2022 IEEE.
ABSTRACT
COVID-19 is making a huge impact both in terms of the economy and human lives. Many lost their lives due to COVID-19 which is found in most of the nations. The number of positive symptoms is increasing rapidly all over the world. To safeguard us from the virus, some protocols have been addressed by WHO in which people has to wear a mask and make a social distancing when moved in public. Therefore, social distancing places an important role in preventing us from the spread of the diseases. The minimum distance between to be maintained is informed at 6 feet informed by the health organizations. When people gathered on a group social distancing could not be maintained even if manual or any kind of technology implemented. Temperature measurement on mass gathering was also a tedious process where the monitoring is essential. Multiple methods such as thermal cameras, temperature sensors for monitoring the personnel has not been efficient. In the proposed work to monitor the social distancing between the persons an ultrasonic sensor is placed to detect the obstacle and an IR sensor to make the rover move. An encoder is used to calculate the distance based on the rpm of the wheel. Based on this input the distance is checked within this limit the obstacle is detected, an alert signal is made using the buzzer. A thermal sensor is used to measure the temperature of the person and an LCD display shows the temperature of the person and distance between obstacles. The proposed system has resulted in identifying the distance and helps in reducing the spread during the pandemic situation. © 2023 IEEE.
ABSTRACT
The main tools for allowing customers to communicate openly and transparently with the company and other stakeholders are their electricity bills. However, last year due to pandemics, some residents petitioned the Madras high court claiming TANGEDCO's technique to measure power was arbitrary and unreasonable during the lockdown that COVID provoked. This was done amid complaints about excessive electricity bills. When compared to bills from other states, TANGEDCO's white meter card for energy bills is found to provide insufficient information on use and rates, according to a survey by the certain associations. Power bills urgently need to be redesigned to include comprehensive billing details and accurate assessments of electricity consumption from closed homes or homes in restricted zones. [4] We proposed and designed a Smart Home Energy Meter Monitoring System to solve this crisis. It consists of three systems. First system: Customized built energy meter with LCD. [6] Second system: Wi-Fi module with the Microcontroller (ATMega328P) and an alert system. Third system: Database (MySQL database). [12] The quantity of power used by the device is measured by an energy meter user and every two months, the final reading of the power consumption is taken by the micro controller where the electricity bill calculation program has been pre-programmed to give the value of power consumed during the two months and amount to be paid by the user and [4] It will be shown on the Energy Meter's LCD. The micro controller with a built-in Wi-Fi module (ESP8266) will send these displayed data to the service provider's database. [2] An alert system has been added to counteract the hefty usage and electricity bills to create awareness to the consumer about the slab-wise tariffs increase in the per-unit cost data that has been set by TANGEDCO. [10] The alert has been set in a way that the consumer receives a message for every 200 unit usage of power. The third system is a database created using MySQL database to transport the data to the service provider. © 2022 IEEE.
ABSTRACT
Thin-film-transistor liquid-crystal displays (TFT-LCDs) have gained popularity due to their widespread use in the production of televisions, laptops, and iPads. TFT-LCD firms' activities that build relationships with suppliers and customers contribute to the emergence of supply networks. A firm's ability to identify risks, however, is complicated, as TFT-LCD supply networks are becoming increasingly global, complex, and interconnected. The extant research on the topological structure of TFT-LCD supply networks is limited, and the risks identified rely on untested assumptions about the topological structure of such networks. To fill these gaps, this study examines the topological structure and COVID-19 related risk propagation in TFT-LCD supply networks from a dynamic perspective. First, the evolution of the topological structure of TFT-LCD supply networks from 2015 to 2020 is explored by constructing a weighted and undirected supply network. Second, the hidden risky sources in TFT-LCD supply networks are revealed by the proposed risk propagation model. The results show that TFT-LCD supply networks are characterised by a ‘hub and spoke' feature and an explicit shift from geographical to global cooperation. Additionally, a ‘robust-yet-fragile' configuration in these supply networks is uncovered, and the hidden risky sources in the main TFT-LCD manufacturers and suppliers and in interfirm cooperations are revealed. These findings will help managers reduce the vulnerability of TFT-LCD supply networks to disruptions and construct more robust and resilient networks.
ABSTRACT
During COVID-19, there was increased use of handheld displays in educational settings. There is growing concern that eye health may be affected by prolonged exposure to the light-emitting diodes used as frontlights or backlights in handheld displays. The potential impact of light exposure from tablet-sized devices with different display technologies and various spectral outputs was assessed in an in vitro model using human retinal epithelial (ARPE-19) cells. Cellular response was quantified by measuring reactive oxidative species (ROS) and by analyzing mitochondrial morphology. Control experiments established a baseline ROS response to hazardous blue light exposure and also that red light resulted in no detectable ROS response. Under identical conditions, ROS response increased with time for all devices. However, different device spectra caused ROS to accumulate at different rates. When operating the devices in the same mode (day or night), cells accumulated ROS two to three times more slowly on exposure to frontlit electronic paper displays compared to backlit liquid crystal displays. With increasing ROS accumulation, mitochondrial morphology shifted from elongate interconnected features typically observed under normal conditions to rounded disconnected features associated with oxidative stress response. © 2023 E Ink Corporation.

ABSTRACT
A novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, also known as COVID-19) is a major problem for many countries in the world. Brunei is also affected by this COVID-19 pandemic in many ways. To alleviate the burden on the health ministry, we developed a low-cost, reliable Internet of Things (IoT) based real-time health monitoring system to diagnose early COVID-19 symptoms for patients at home. This diagnosis includes the three important physiological parameters such as body temperature, heart rate and oxygen saturation level (SpO2) in the blood. This system comes with an OLED LCD to display the three parameters. Apart from that, these parameters are also displayed on a mobile dashboard using the Cayenne IoT platform for easy access. This system was evaluated against many people, and the results were compared against the industry-standard pulse oximeters which are remarkably close and dependable. © 2022 IEEE.

ABSTRACT
One of the most pressing challenges facing restaurants since the COVID-19 outbreak began is personnel. A staffing scarcity across the business has resulted in a slew of issues, including significantly longer wait times and irritated clients. A robot waiter may make a huge impact in a restaurant in this situation. This research led to the formation of a low-cost Arduino-based Android application control Robot that can work as a restaurant waiter. The proposed model can follow a path, avoid obstacles, serve meals to a specific consumer, and return to the kitchen on its own. To precisely follow the line, the PID algorithm is utilized. To detect potential obstructions, a sonar sensor is used. On an LCD, messages and warnings are displayed. An Android app that allows the chief to select a particular table for serving meals. For convenience, the robot's current state is displayed in the application. Our testing results show that the robot performs satisfactorily over 90% of the time. It should be emphasized that the offered model is adaptable to any restaurant. © 2022 IEEE.
ABSTRACT
Heart rate and body temperature are some of the important components of a person's main vital signs that need to be monitored regularly and periodically. The detection system technology continues to develop which allows a person to detect his own condition, to avoid exposure to COVID-19. However, the tools that are developing in the market are quite expensive and sometimes complex in operation because they are external products, so that it becomes a difficulty in itself. For this reason, it is important to design a detection device with sensor components that exist in the country and with a simple design so that it is easy to operate and inexpensive. In this paper, utilizing pulse sensors and AD8232 sensors to detect heart rate and MLX90614 sensors to measure body temperature, then NodeMCU ESP8266 to process sensor signals received and will be forwarded to the Display (LCD) to display the results carry out the design and development of an integrated sensor system. From the research results, the accuracy of the MLX90614 temperature sensor is very good with the achievement of 99.24% and the pulse sensor with the achievement of 98.86%. For the test results on each sample obtained accuracy values of 98.4% and 99% for the temperature sensor, and 92.3% and 92.2% for the pulse sensor, respectively. From these results, it is very clear that the sensor design deserves to be promoted as a quality product. © 2022 IEEE.

It utilizes basic technology and may be assembled with commonly available, low-cost components. The device mainly uses the NRF24L01 RF module, ultrasonic sensor and MLX90614 thermometer sensor for the monitoring system. It is also composed of other electronic components like switch, LCD display and power source. The device will prevent the virus from infecting you, your family, and your friends. Results have shown that this device is applicable for distance and temperature monitoring of a person as an aid to prevent the spread of the virus. © 2022 IEEE.
ABSTRACT
COVID-19 is an ongoing global pandemic and is continuing to be a fast-spreading virus all over the world. It transmits when people breathe in air contaminated by droplets and small airborne particles containing the virus. The risk becomes highest when people are nearby, but they can be over longer distances, while indoors. It is necessary to isolate such infected persons in public places with large gatherings. In addition to screening them, individual protection measures can also be taken.Two primary requirements that fulfil the entry to the public are by scanning of temperature to prevent person suspected and also to ensure one has masked face properly to permit entry. At the moment, all places use this system. But they are manual and depend on the person inspecting temperature and mask. There are few automated processes, but they do not have automatic entry control. Thus, there are risks of false entry of people inside the public place.In this paper, an integrated approach in mask detection and temperature scanning, indicated visually by LED and LCD Display, and further control entry with the operation of boom barrier has been presented. The information is also recorded to identify each entry. Open CV is used to detect masks and obtain better accuracy. An infrared temperature sensor and a proper guide to scan the temperature are used. Each step of the process is implemented on one Raspberry PI-based board. The system is suitably packaged and demonstrated. © 2022 IEEE.
ABSTRACT
Only vaccination can not prevent COVID-19 infection. Social distancing and other preventive measures like - frequent hand washing, wearing a face mask can reduce the rising infection rate of COVID-19. It is not feasible to maintain social distancing and ensure hand sanitization in public places by humans as COVID-19 can affect that person or be contaminated by him/her. An automated social distancing system will play an essential role in maintaining social distance within certain boundaries. An automatic social distancing system called 'COV-SSDS' has been proposed in this work. In COV-SSDS, a person has to disinfect the hands with a sanitizer after being detected by the infrared sensor because the servo motor control door does not open without hand sanitization. If the person does not stand in the proper place, he/she will be notified. A liquid crystal display module has been used to display the number of people in the queue and the occupied slots. An alert generation system to alert the people about occupying the empty slot and a power backup unit was also attached to this system which was not found in previous studies. According to the features, feasibility, maintenance, and cost analysis, 'COV-SSDS' is worthy of the previous works. © 2022 IEEE.

ABSTRACT
Currently, Coronavirus has become a global crisis, affecting countries all over the world. It caused death to millions of people. As this virus is widespread, necessary precautions are not being taken by the people. In recent days, checking the temperature is mandatory, since fever is one of the foremost symptoms to sense the presence of this virus. Checking the person's temperature manually is simple, however it is not safe if the other person has this infection. So, an IoT-based Contactless Covid-19 doorbell is designed to act as a doorbell and also scan the temperature of the person. The scanned temperature can be viewed in the blynk app. Another feature is that a camera is fitted in the system so that one can view the person in the app. If the person's Body Temperature is normal, the person can allow them inside by accessing the option in-app to open the door. Once the option is given, it unlocks and opens the door to go in. After a few seconds, it closes the door automatically. If a person has a high Body Temperature, the system alerts the user through the app, that the person has a fever. One can allow them inside, as per their choice. A sanitation system is also fitted, to sanitize their hands. An LCD display is also fitted, to display the Temperature, and the Welcome messages. The contribution of IoT, makes the user see the temperature, the person on the front door, and control the door anywhere in the home. © 2022 IEEE.
ABSTRACT
Social distancing is the one of the preferred ways to get out of the current situation and it has become difficult to follow it. Most people use public transport as a medium to travel. It becomes very difficult to maintain an effective social distance in public transports. So, we have planned to give a solution to address this problem by ensuring safeness in buses. Here, we kept a fixed limit for persons entering into the bus and before that they had to pass the temperature check and mask detection checks. The device consists of a Raspberry pi Module which acts as a system, a Camera module, PIR Sensors, Infrared Temperature Sensors, LCD Monitor. LCD Monitor shows the details of the number of persons that can be accommodated in a particular bus and the number of people present inside the bus. Temperature sensors, such as infrared temperature sensors, are used to detect the temperature of people entering the bus. It is captured and determined whether or not the person is wearing their mask in the entrance by the Camera Module. PIR Sensors are used to monitor the count of the persons entering or exiting the bus which is displayed in the LCD monitor. So, these work together and make the entry screening while entering a transport system. © 2022 IEEE.
ABSTRACT
The coronavirus or Covid 19 is a highly infectious disease which took a huge toll of human lives between the years 2019 and 2021. The global spread of the virus has overwhelmed health systems, and caused widespread social and economic disruption. Strategies in the control of an outbreak are screening, containment and mitigation. The process of collecting and recording vital signs can be a time- consuming process without the right tools. The main motive of the invention disclosed here is the integrated portable healthcare solution that will help in quickly carrying out Covid screening vital test measurements such as temperature, pulse and blood pressure which will not only be used during epidemic/pandemic but also during other emergencies/patient triages and also to keep a track of all affected Covid patient's screening results by the healthcare professionals. Monitoring of vital signs is necessary for the efficient and effective patient management. Vital signs are regularly measured at specific intervals in patients in the Emergency department or remotely. This project mainly focuses on the integration of three sensors (i.e.) MAX30100 sensor, MLX sensor and digital BP sensor and producing the values in the same kit. This smart device is used to monitor the person's temperature, blood pressure, SpO2, heart rate and by comparing all the four threshold values, the final result is displayed as normal or abnormal values simultaneously in the mobile app and the LCD display. The system can be used remotely as well in the healthcare setting where patients are in the waiting queue. Based on the results, intimation messages are sent to the concerned patient or healthcare professional who's mobile is linked with the device and in abnormal conditions, the alert message is sent to quarantine themselves from the general public. This continuous monitoring helps in the initial screening for Covid-19 at the early stage, where the results can be checked and timely advices can be given by the family members, doctors and the medical professionals. © 2022 IEEE.
ABSTRACT
This article aims to present the efficiency evaluation of the ozone gas concentration generation by the commercial ozone generator for disinfection in residential buildings during the COVID-19 pandemic. The objectives of the research are 1) to evaluate the efficiency of the ozone gas concentration generation by the ozone generator available in the market;and (2) to determine its appropriateness. The 2 gram/hour ozone generator was placed near an air-conditioner for 60 minutes following the instructions of the manufacturer. Then, the ozone concentration measuring devices were developed using the Winsen® ZE14 ozone sensor, which display the results in LCD screen, save them in a micro-SD card in the form of an Excel file (.xlsx). The devices were then placed at 3 positions;4 meters, 8 meters, and 12 meters of the generator. Finally, the data of the ozone concentration collected from each position was processed and analyzed. The results revealed that (1) the 2 gram/hour commercial ozone generator was able to neutralize the pathogens (0.5 ppm in 5 minutes);and (2) the disinfection was appropriate for the 348 m3 room. Using it in larger room reduces its efficiency of disinfection. In conclusion, it is crucial to select the generator by considering its capacity and the size of the room for the highest efficiency according to the standards. The generator can be used assuredly and efficiently to disinfect and reduce the risk of infection. © 2022 IEEE.
ABSTRACT
COVID-19 is an infectious disease that causes serious pandemic. There are many means to contradict the outspread of the microbe and one such way is to sterilize the hands by washing with soap for 20 seconds. Despite washing hands regularly, there is a tendency to touch the contaminated surface in the tap and door handles. In order to make the hands contamination-free before entering the premise, a solution that a person will be allowed to enter only after hand washing has been implemented. Having an automatic faucet and door which will be controlled using the micro controller Arduino Nano wherein various sensors like IR sensor and other devices like servo motor, relay module and LCD display will be interfaced with the micro controller has been proposed. An IR sensor will be placed at the door that senses whether the person has washed his/her hands or not and grant access for the entry. Another IR sensor will be placed at the faucet and it will sense the person's hand and control the water flow accordingly. The proposed system will ensure whether people have washed their hands before entering their premises and grant access accordingly. © 2022 IEEE.
ABSTRACT
In this paper we propose the use of secure contactless Electronic Voting Machine(EVM). We used a Radio Frequency Identification(RFID) reader to authenticate the voter's identity, and Infrared(IR) sensors to implement contact-less voting to curb the spread of Covid-19. Significant components used are Arduino Uno, FC-51 Infrared Module, EM-18 RFID reader, keypad, and I2C PCF5874T for Liquid Crystal Display(LCD). The software used to program these components is Arduino IDE. This EVM ensures security in two ways - authorizing the identity of the voters before they are allowed to vote, as well as providing a contact-less experience for the voter. An extra layer of security is added, so that when the candidates and Election Commission are present and enter their respective passwords, only then can the results be accessed. © 2021 IEEE.
