A smart healthcare monitoring system for patients using IoT and cloud computing

Health monitoring systems are rapidly growing in recent times, Continuous monitoring of the patients is one of the big challenges for hospitals. Smart systems have been established to track the patient present health status;we focus on monitoring the patient's blood pressure, body temperature, Heart rate. In this project we use Arduino Mega 2560 which is a microcontroller board based on the ATmega2560 comments. In this paper, Embedded C language by using Arduino is used to obtain the sensor values. IOT data cloud is used in this project. IOT is used in healthcare system to track the patients' health condition as a monitoring device. Cloud computing develops as a platform for IoT data storage, processing and analytics because of its simplicity, expandability and affordability. Transmit sensor values to Arduino and it sends to GSM and WIFI module to monitor the parameters of the patients. In this project the notifications of patient's health status are sent to the caretaker and nurse, simultaneously it is updated in webpages also for the doctor's reference. Taking in account, COVID 19 Pandemic is highly infectious and spreadable disease, so to maintain the social distance, this monitoring system is needed. It reduces the need for face-to-face appointments with doctors in hospital. ECG sensor is also used to decide the heart activity of the patients. This project aims for the patients who are in continuous monitoring and bedridden. The GSM and IOT technologies give the architecture for healthcare in this project. © 2023 Author(s).

LFR Waiter: Arduino Based Android Application Controlled Waiter Robot

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.

Teaching Devices and Controls during the Pandemic

This paper presents our experience in teaching Devices and Controls remotely during the COVID-19 pandemic in Autumn 2020, at the School of Engineering and Technology, University of Washington, Tacoma. As a core course for Computer Engineering and Systems students, and the only control course in this program's curriculum, we tried our best to minimize the impact brought by the remote teaching and learning, bridge the gap between system theories and practical applications, and expose students to the state-of-the-art technology in the field of embedded control systems. Our efforts include distributing each student an easy-to-use Arduino Mega2560 starter kit, enhancing students' understanding of control theories by using analysis/design tools supported by MATLAB/Simulink, and remotely supervising individual labs and a final project which implements a PID controller through both MATLAB/Simulink and Arduino IDE. In addition to four-hour lectures in the virtual classroom, students also take two-hour virtual lab each week, and complete the course project by the end of quarter. The course evaluation results showed that although challenged by the physically isolated setting, students gained knowledges of the embedded control systems, and in particular, the hands-on experience obtained from virtual labs and the individual project.

Development of an Automated Medicart for Covid-19 and Other Contagious Diseases Application

Automated carts in the hospitals that can help the patients with their preliminary needs are new tech introduction to the world. Today's world is facing the worst ever time of the history caused by the deadly contagious virus named Corona Virus (COVID-19). Keeping a good distance with proper precautions will address the problem in the more suitable minimizing way to not getting infected. Commercially developed carts are still not available in the hospitals. This paper presents the development of an automated cart which can be manually controlled by remote or it can follow the line and can deliver the necessary goods and medicine to the patients. The purpose of this research is to introduce autonomous vehicle in the hospitals keeping in mind that it can help covid-19 patients minimizing the contact of medical personnel with the patients. This research aims to design a microcontroller and sensor based automated cart in the hospitals. No human intervention is required during its task execution while it's on the line following mode. Safety measures are provided to AGC by using sensor for obstacle detection to avoid collision. © 2021 IEEE.

A Low-Cost Smart Parcel Box System with Enhanced Security

A global pandemic of covid-19 has hastened the growth of online shopping or E-commerce. Nowadays, E-commerce transactions provide various products from luxury goods and services to everyday necessities. While the popularity of online shopping has grown fast, there are several common issues that shoppers experience. Common problems that customers experienced are failed delivery, missing parcels and even the criminal case. Malaysia has introduced Pos Laju Ezi Box Kiosk, but still contemporary Kiosk type approach for the delivery system has some problems such as high initial installation cost, the expense of management system and especially security weaknesses in the wireless communication. To overcome the aforementioned problems, this paper proposes a low-cost smart parcel box system that will be installed at individual homes with enhanced security. This system used Arduino Mega 2560 to control all the processes of the developed system. The system will be initiated when couriers send the parcel’s tracking number as a message to the user via applications to get the password. For security purpose, password will be provided once the courier’s message is the same as the message specified by the user. Couriers then can enter the password provided and insert the parcel into the smart parcel box. The proposed lowcost smart parcel box system ensures that parcels are delivered safely and securely to the customer’s door. © The 2022 International Conference on Artificial Life and Robotics (ICAROB2022).
