In this Arduino Tutorial, we will learn how to interface HC-SR501 PIR Sensor with the Arduino Board for detecting motion. PIR stands for Passive Infrared Sensor, also known as pyroelectric sensors.

In this project, we will learn how to interface a PIR sensor with a microcontroller like Arduino. Detecting motion or movement has always been important in most projects. With the help of PIR sensor, ...

The PIR motion sensor consists of 3 pins-VCC, GND, and the Data Output Pin. VCC is the power pin of the module. Out is the data Output pin of the module.it goes high when motion is detected. GND is ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...
