ABSTRACT
The greatest threat to the word in recent days is the spread of COVID 19 virus throughout the world. To tackle this problem government of India has implemented various restrictions to be followed to stop the spread of the COVID 19 virus. But most of the time general public forget their responsibilities and don't follow these restrictions, especially in situations like when their favourite hero's movie releases in the theatre, and in spending time in hotels, malls and in other entertainment places in spite of governments occupancy restrictions in those places. In order to address this problem we propose an IoT based Smart System for monitoring the occupancy in such entertainment spots and screen the public entry if they dint follow the protocols such as if they dint wear mask or if they have body temperature. This proposed system is implemented on a Raspberry Pi 3B+ processor which runs on a Broadcom processor. For monitoring the occupancy and screen the visitors for mask, we use a Passive Infrared Sensors and Pi camera to count the person entering into the premises. And we use a MLX90614 Infrared temperature sensor for screening the public entry with high temperature. The complete system is implemented using python programming and the details will be uploaded to cloud, authorities can monitor this from a remote place so that the spread of COVID 19 can be restricted in pubic entertainment spots.
ABSTRACT
Coronavirus flare-up chances human existence and it challenges the general wellbeing. Hand cleanliness, an extremely basic activity, is very much acknowledged to be one of the essential methods of decreasing medical care-related disease and of improving patient security. These days wearing masks, utilizing hand sanitizers, checking temperatures are being done in all places, and so forth yet at the same time in many spots individuals utilize conventional sanitizer gadgets which build the spread of microorganisms. Normally an individual is in charge of observing the body temperature and sanitizer level by taking a chance with his life. This survey Internet of Things (IoT) based hand sanitizer dispenser with temperature and level monitoring distinguishes the presence of the people and gives out alerts in form of the human voice to sanitize their hands if the dispenser goes unrecognized. Furthermore, we have a contactless sanitizer dispenser to stay away from contact among humans and dispensers which will keep us away from the further spread of infection and microorganisms. © 2022 IEEE.
ABSTRACT
The government agencies, worldwide, are implementing the guidelines given by the World Health Organization (WHO) to mitigate the rise in the number of cases of COVID-19. Due to the lockdown imposed during the outbreak of COVID-19, there has been a disruption of economies especially for micro enterprises. Therefore, there is a need of a solution which can facilitate continuity of work at workplaces, while ensuring that social distancing norms are being followed. An IoT based solution has been proposed through this paper which satiates this need. The device detects the moving person in the vicinity of 3-meters using Ultrasonic and Passive Infrared (PIR) sensors. Different Light Emitting Diodes (LEDs) of the Neopixel ring glow according to the distance between the approaching person and the user. The buzzer in the system buzzes when the distance is less than 175 cm. The proposed de vice will be a viable solution for micro enterprises as workers can work safely even during strict lock-downs due to the waves of the pandemic. © 2022 IEEE.
ABSTRACT
Conventional streetlight’s constant need for high power and the ill effects it has spawned on the environmental ecosystem has led researchers to adopt the idea of smart lights in order to minimize energy consumption and maximize power efficiency. This paper proposes S-LIGHT, which is a PWM-based LED adaptive light controlling system that can be deployed at public parks and other outdoor recreational venues, which applies intelligent illumination control of an LED lights. The design is based on Pulse Width Modulation technique which optimizes the overall power consumption and simultaneously supporting a multi-functional and user-friendly post. Smart street lighting aims to make cities feel safer at night, make lights more efficient, and substantially reduce costs of maintenance and energy by integrating sensors and alternative technologies to automate the light. S-LIGHT uses an Arduino UNO board along with a Passive Infrared (PIR) sensor to swiftly increase the brightness of the high-power LED light during the night in the presence of human motion, and a Light Dependent Resistor (LDR) sensor to turn on/off the light by adapting itself to the time of night/day. S-LIGHT also provides a multi-functional post that supports an emergency button feature that easily initiates an Emergency call to the police, a surveillance camera that streams live footage of the area, and an LCD screen that displays to the public awareness messages about the COVID-19 pandemic. © 2021 IEEE.
