TMOS PIR Unit is a high-sensitivity infrared sensor unit for presence and motion detection. It uses the STHS34PF80 chip solution. It communicates with M5 devices through I2C (default address: 0x5A). Its working principle is based on the black-body radiation principle described by Planck’s law, which allows it to monitor ambient temperature and detect human presence and motion. The sensor can distinguish between stationary and moving objects and has an 80-degree field of view, providing a wide detection range. Additionally, it supports adjustable sampling frequency and gain modes to meet different application needs. It is suitable for applications such as alarm systems, smart lighting, and occupancy detection.
