We are all having a very tough time keeping ourselves and our belongings sanitized on a regular basis due to the covid-19 pandemic. A number of people visit our homes, so sanitizing ourselves is a must. But, why sanitize all starting from the doorbell and to what not? So irritating right?
We have something for you. With this idea of the touchless doorbell take a break from sanitizing your doorbell repeatedly and also stay safe and happy!

How It Works
The distance sensor module emits a beam of ultrasonic waves which the human eye cannot see. When this emitted beam hits any object, it gets reflected onto a small sensor in the module, thus measuring the distance.
Buzzer is a simple output module. All that it does is make noise when an input signal is given to it. Connect the distance sensor and the buzzer module. The buzzer module beeps whenever the distance is less. So, on waving your hand in front of the distance sensor the buzzer starts beeping.
