The PIR41 includes three sensitivity detectors and an integrated circuit to save energy and offer practical functions. The PIR41is designed to automatically turn lights on when motion and body heat is detected. The sensor uses the infrared energy from humans as a control-signal source; the load is activated as soon as one enters the detection field. It includes a day/night sensor to easily identify between day and night, and it is easy to install.
