In this project we will learn how to interface Arduino with PIR sensor and design an arduino based motion detector project with circuit diagram and code.

In this article, we interface HC-SR501 PIR sensor module with ESP32. HC-SR501 PIR sensor module allows you to detect when a person or animal moves in or out of the range of your sensor.

A PIR sensor on the front of the can detects when somebody gets close, and plays a message reminding them to make use of the trash cans provided on the playground.
