Product description: SparkFun Mini Human Presence and Motion Sensor - presence and motion sensor - STHS34PF80 - Qwiic - SparkFun SEN-23253
Presence and motion sensor using high-sensitivity infrared technology. The module is equipped with a factory- calibrated STHS34PF80 system and is designed to measure the amount of IR radiation emitted by an object in its field of view. The information collected by the sensor is digitally processed by an ASIC that can be programmed to monitor motion, detect presence, or trigger an alarm during excessive temperatures. Thanks to its exceptional sensitivity , the STHS34PF80 can detect human presence from a distance of up to 4 meters (without the need to use an optical lens).
