Mikroe PIR Click

Mikroe PIR Click is a pyroelectric sensor that generates a voltage when exposed to infrared radiation from live bodies. The Mikroe click is equipped with the KEMET PL-N823-01, which uses the pyroelectric effect of ceramic by absorbing infrared rays emitted from the human body. The white plastic Fresnel lens covering the sensor filters visible light. This detects the natural infrared signature produced by humans. The click can also see infrared rays without using lenses.
