AM312 Mini PIR Motion Sensor Module – Low Power Human Detector

The AM312 Mini PIR Motion Sensor Module is a compact, high-reliability solution for detecting human movement. Based on advanced digital intelligent infrared technology, this sensor is significantly smaller and more power-efficient than standard PIR modules (like the HC-SR501), making it the top choice for space-constrained and battery-powered applications.

Digital Intelligence & High Sensitivity Despite its tiny size, the AM312 offers superior immunity to electromagnetic interference. It detects the infrared heat signatures of moving bodies within a 3-meter range and a 100-degree cone angle. When motion is detected, it outputs a high signal, allowing for easy integration with microcontrollers like Arduino, ESP32, and Raspberry Pi

Plug-and-Play Efficiency

This module is designed for simplicity and efficiency. It features a wide operating voltage range of DC 2.7V to 12V and consumes less than 0.1mA of power. With a fixed 2-second delay and repeatable trigger mode, it requires no manual tuning—just connect it and it works.

Key Features

• Ultra-Compact: Tiny footprint fits into small toys, lamps, and hidden security cameras.

• Low Power Consumption: Uses <0.1mA, ideal for long-term battery use.

• Wide Voltage Support: Works seamlessly with 3.3V and 5V logic systems (2.7V – 12V input).

• Repeatable Trigger: The sensor keeps the output HIGH as long as motion is detected within the sensing field.

• High Reliability: Digital signal processing reduces false alarms.
