Mikroe PIR Click board pyroelectric proximity sensor

The PIR Click board, from Mikroe, is a pyroelectric sensor supporting human presence detection. The product is equipped with an onboard PL-N823-01 pyroelectric proximity infrared (PIR) sensor from KEMET Electronics, which enables human detection through glass or resin. The high-performance sensor is suitable for a range of consumer electronics and Internet of Things applications, such as office automation, contactless switching, lighting, air conditioners and more.

The device generates voltage when exposed to infrared radiation from human bodies. The low-power sensor is passively triggered by moving subjects, enabling it to deliver energy-saving performance in applications relying on human presence detection. The product includes a white plastic Fresnel lens that filters visible light, allowing the sensor to detect the infrared signature emitted by humans. The onboard PIR sensor features KEMET’s piezoelectric ceramic material and element structure, said to result in greater freedom of design for products using resin or glass.

The product is part of the Mikroe Click board ecosystem, a modular design that enables developers to connect any Click board to a standardised mikroBUS socket with no hardware configuration required. The versatile mikroBUS standard socket contains all necessary pins to connect Mikroe’s complete range of Click boards, including wireless communication modules, sensor modules and other accessories.
