STHS34PF80TR

STHS34PF80TR is a low-power, high-sensitivity infrared (IR) sensor for presence and motion detection. It is an uncooled, factory-calibrated, infrared motion and presence detection sensor with operating wavelength between 5µm and 20µm. The STHS34PF80 sensor has been designed to measure the amount of IR radiation emitted from an object within its field of view. The information is digitally processed by the ASIC, which can be programmed to monitor motion, presence, or an overtemperature condition. Thanks to its exceptional sensitivity, the STHS34PF80 can detect the presence of a human being at a distance up to 4 meters without the need of an optical lens. The STHS34PF80 is housed in a small 3.2 x 4.2 x 1.455 (max) mm 10-lead LGA package. Applications include presence and proximity sensing, alarm / security systems, home automation, smart lighting, IoT, smart lockers and smart wall pads.
