M5Stack U185 TMOS PIR Unit

M5Stack U185 TMOS PIR Unit is a high-sensitivity infrared sensor for detecting presence and motion. The M5Stack U185 features the STHS34PF80 chip and connects to M5 devices via I2C. Using black-body radiation based on Planck's law, it monitors ambient temperature and detects human presence. The sensor can distinguish between stationary and moving objects with an 80° field of view for wide detection. It also offers adjustable sampling frequency and gain modes, making it ideal for alarm systems, smart lighting, and occupancy detection applications.
