Description

The HC-SR501 PIR Motion Sensor Module is a widely used and versatile device for detecting motion. It’s based on passive infrared (PIR) technology, which senses changes in infrared radiation emitted by objects, particularly humans. This module is equipped with a jumper on the back, allowing you to configure the trigger mode for different applications.

This is a HC-SR501 PIR with Jumper at back for trigger.

The PIR Motion Sensor Detector Module HC SR501 allows you to sense motion. It is almost always used to detect the motion of a human body within the sensor’s range. It is often referred to using “PIR”, “Pyroelectric”, “Passive Infrared” and “IR Motion” sensor.

The module has an onboard pyroelectric sensor, conditioning circuitry, and a dome-shaped Fresnel lens. It has a delay time adjustment Potentiometer and sensitivity adjustment Potentiometer. Compatible with ARDUINO, RASPBERRY PI, AVR, PIC, 8051, etc.
