The KEMET USEQMSEA221680 is a Passive Infrared (PIR) motion sensor module designed for optical sensing applications. It features a 30-pin surface-mount device (SMD) configuration, which ensures compactness and ease of integration into electronic systems. The sensor is equipped with a 1.65mm filter aperture, optimizing its ability to detect infrared radiation from human motion while minimizing the impact of ambient light. This sensor is ideal for use in motion detection, security systems, and other applications where the presence or movement of objects needs to be monitored. The combination of its small form factor and specialized optics makes it well-suited for space-constrained designs requiring accurate and reliable motion sensing capabilities.
