By interfacing a HC-SR04 ultrasonic sensor and an LED traffic light with an Arduino Uno I was able to create a portable social distancing meter that will help you and the people around you keep their distance during the pandemic.Details
I created this project to make an open source solution to the social distancing problem. It only contains four items and is totally portable. The 9V battery can be easily replaced as needed and with a clear user interface no one will misunderstand what the lights mean.
The way the code is currently set-up there are three modes. Closer than six feet to the sensor is a red light, six to eight feet is a yellow light, eight feet and beyond is a green light. It is also lightweight and unobtrusive so it can be taken anywhere.Files
