Low power IR sensor can replace passive IR detectors

Designed to enhance security systems, home automation equipment and IoT devices that typically use passive infrared (PIR) sensing, the STHS34PF80 is a novel human presence and motion detector, said STMicroelectronics. The STHS34PF80 sensor contains thermal transistors that can detect stationary objects, whereas conventional PIR detectors require a detected object to be moving to produce a […]
