Nicera PSUP43-12 Pyroelectric Pir Sensor Unit

This PIR module works on the pyroelectric principle, where a change in detected temperature produces an increase or decrease in generated electric potential. The module consists of a quad element passive infrared sensor, a lens and associated circuitry, mounted on a PCB. Having a wide field of view in the horizontal and vertical planes as well as 12 detection zones make this module suitable for a wide range of applications.
