In this project, we will build an Auto Hand Sanitizer Dispenser with an LCD which also shows the live count of Coronavirus cases. This project will use ESP32, Ultrasonic Sensor, 16x2 LCD Module, Water pump, and Hand Sanitizer. We are using Esri’s API Explorer to get the live data of Covid19 infected people. An ultrasonic sensor is used to check the presence of hands below the outlet of the sanitizer machine. It will continuously calculate the distance between the sanitizer outlet and itself and tells the ESP to turn on the pump whenever the distance is less than 15cm to push the sanitizer out.
Watch the video below for the working of this automatic hand sanitizer dispenser.
