Arduino Uno and Ultrasonic Sensor Based Social Distancing Model to Avoid Spread of COVID

Social isolation has been shown to be the sole effective defense against COVID-19, according to the World Health Organization. In this study, a prototype for tracking human positions in an outdoor setting utilizing sensors and a microcontroller is proposed. This tool is especially beneficial for keeping a safe distance from people in public settings, which was crucial during the COVID-19 epidemic. Getting a signal to preserve social distance from someone approaching us is crucial. Social distance is necessary at workplaces, on public transit, and in grocery shops. We deployed the sensors on the rear to inform the individual for preserving social distance since, in general, we are mindful on the frontside but not on the backside.
