Description

PIR Motion detection sensor works on Passive infrared technology. It measures infrared (IR) light radiating from objects in its field of view. They are most often used in Motion detection. This module uses BIS0001 IC for detecting motion. Whenever there is any motion by a heat radiating object then this module will give an trigger output.

Passive means this device does not emits or radiates any energy for detection. Every object above absolute zero emits heat, this heat signature is in Infrared wavelength so those energy can not be seen by naked eye, but they can be measured by infrared devices.

Sensor is covered with Fresnel Lenses, which create a wide angle of detection and also used for noise filtering.

Read this article for their working.

Almost all the PIR Motion Detection Sensor available are work same way with very minor differences.

How they work and how we can use them in different applications.  Read is Tutorial.
