The AM312 Mini PIR (Passive Infrared) Sensor Module is a compact motion detection device designed for low-power, high-sensitivity human body sensing. This sensor utilizes digital signal processing for improved resistance to environmental interference and consistent detection performance.

It features a repeatable trigger mode, meaning the sensor maintains a high output as long as motion is detected within its range. Ideal for battery-powered applications, the module draws minimal current and operates on a wide voltage range from 2.7V to 12V DC. Its miniature size makes it easy to embed in lighting control systems, automatic doors, alarms, and DIY smart home projects.
