PIR Movement Sensor Board

This PIR Motion Sensor detects movement up to 5 metres away with a 100° detection angle, making it ideal for security projects, automatic lighting, occupancy sensing, and other motion-activated projects.

A PIR (passive infrared) motion sensor is a device that detects physical movement within its field of vision by sensing changes in infrared radiation.

This sensor works on the principle of detecting thermal signals emitted by objects, mainly warm-blooded creatures like humans. The "passive" in the name refers to the fact that the sensor itself does not emit or radiate any energy for detection.

Easily connects to microcontrollers via a digital pin. When it detects movement, it sets the output digital pin to HIGH. The angle that the sensor "sees" is 100 degrees and reaches up to 5 meters. It has a potentiometer for delay (how often to check for movement).

It is often used in a variety of applications, including home security systems, automatic lighting, and energy management, among others.
