Touchless Hand Wash with Soap and Sanitizer
Touchless Hand wash with Soap Sanitizer using Arduino
Today, we are going to make an automatic hand sanitizer dispenser using an Arduino board. As you all know, COVID-19 is spreading like wildfire and all you hear is, wear a mask, clean your hands, use contactless alternatives, and practice social distancing.
Why Contactless Hand Sanitizer Dispenser
using Arduino?
Hand sanitizer is one of the best ways to get rid of all the harmful germs and viruses in our hands. But what if a healthy person uses a hand sanitizer, which was previously used by a person who was infected by COVID19? In this case, there is a chance of spreading the virus.
How Touchless Hand Sanitizer Dispenser
using Arduino works?
we use an ultrasonic sensor to calculate the distance of our hand from the sensor. If the hand is close to the dispenser, Arduino will activate the ultresonic sensor and the servo motor will be expelled out of the bottle through the tube.
