Human Body PIR Motion Sensor PH-WHW is a highly reliable sensor designed for use in burglar alarm systems. This sensor detects human movement using passive infrared (PIR) technology, making it ideal for securing areas such as homes, offices, warehouses, and garages. With a wide-angle detection range of 8-12 meters and a 110° angle, it offers excellent coverage for enhanced security.

The device features advanced components, including fiberglass circuit boards that allow stable operation even at high temperatures. It also includes pet immunity for animals up to 15 kg, reducing false alarms. The PIR sensor operates at a low quiescent current of less than 5uA and supports long battery life, up to 2 years, making it efficient for continuous use.

Key benefits of this product include its infrared trigger, low battery indicator, and customizable alarm intervals. Operating on a frequency of 433/868MHZ, the sensor transmits signals up to 120 meters in open areas.
