The AM312 Infrared PIR Motion Sensor Module is a compact, low-power, and highly sensitive motion detector designed for human presence detection.
It uses Passive Infrared (PIR) technology to detect motion by measuring changes in infrared radiation emitted by humans. This makes it ideal for Arduino, Raspberry Pi, ESP32, STM32, and IoT-based automation projects.
With its tiny size, low current consumption, and easy-to-use 3-pin interface, the AM312 PIR module is perfect for security systems, smart lighting, automatic doors, robotics, and home automation applications.
