All countries are facing the coronavirus pandemic. This disease is highly contagious. Best way to avoid it is to keep social distancing. But maintaining the distance is difficult in crowded places. No one follows the markings. I am giving a electronics device which will alert us if someone comes very close from behind. The Passive Infrared (PIR) sensor module is used in the circuit as shown. This module may be hookup at the back side of the shirt collar as shown in the sketch. There is a provision to adjust distance up to 15 ft and alarm time as well. If someone comes within the vicinity of distance adjusted to, say 6 ft, the PIR sensor detects the movement by emitting infrared signals which are returned back to the sensor to activate the circuit and alarm. To maintain social distancing from behind it is usually difficult to control. Front view and right and left can be viewed. In such situation PIR sensor circuit will alert a person to maintain sufficient social distance.
