Distance monitoring alarm for covid 19 using ultrasonic sensor

A social solution recommended by World Health Organization (WHO) authorities in this COVID-19 is to cover a physical distance of six feet, a mandatory safety measure in shopping centers, schools and other crowded areas In this COVID-19 environment, everyone is conscious about their safety, so we came up with the idea of developing this novel device Most of the time, our focus is on the people in front and the side of the us, but were not able to monitor the people behind us The main objective of this project is to maintain social distance between the people In this proposed work PIR sensor, Ultrasonic sensor and Arduino UNO are used When the PIR sensor detects motion, the ultrasonic sensor measures the distance between people If a person is in the critical range of six feet around him, this device will warn the person If the distance is less than six feet, this buzzer indicates the presence of infected persons © 2021, Annals of R S C B All rights reserved
