Product Description

ZSBG323671 Pyroelectric Sensor

The Zilog ZSBG323671 is a Passive Infrared (PIR) sensor designed for high-performance motion detection applications. It features dual-element balanced differential sensing elements, high PSRR, and built-in EMI compensation. The sensor is tuned to an 8-13um wavelength spectral filter to minimize unwanted IR interference. It is suitable for applications such as security motion detectors, video doorbells, IP cameras, and wall-mounted lighting/HVAC controls.
