AM312 Mini PIR Sensor

The AM312 Mini PIR Sensor is a highly efficient and compact passive infrared (PIR) motion detection module. It utilizes pyroelectric technology to detect changes in infrared radiation emitted by human bodies, triggering a digital output signal. This sensor is designed for low power consumption, making it an excellent choice for battery-operated applications such as wireless security alarms, automatic door lights, and energy-saving systems. Its small form factor allows for easy integration into various DIY electronics projects and embedded systems. Key features include a wide operating voltage range (2.7V to 12V DC), extremely low static power consumption (<0.1mA), and a fixed delay time of 2 seconds. The sensor features a digital output that is easy to interface with microcontrollers like Arduino, ESP32, and Raspberry Pi. Common applications include home automation, motion-activated lighting, security surveillance, and interactive installations. Choose the AM312 for its reliability, low power profile, and ease of use in creating intelligent motion-sensing solutions.
