AM312 Mini PIR Motion Sensor Module (2.7–12V) | Infrared Body Detection
Add reliable and ultra-low-power motion detection to your electronics projects with the AM312 Mini PIR Sensor Module.
Using passive infrared (PIR) technology, it detects human presence and movement and outputs a clean digital HIGH signal.
Its wide voltage range DC 2.7–12V makes it fully compatible with 3.3V systems such as:
ESP8266, ESP8285, ESP32, STM32, Arduino, and other microcontroller boards.
⭐ Features
-
High sensitivity & reliable performance
Built with digital signal processing to reduce noise and improve stability. -
Ultra-low power consumption
Static current <0.1mA — ideal for battery-powered applications. -
Miniature size: only 10 × 8 mm
Small lens design, perfect for compact or embedded devices. -
Repeatable trigger mode (Auto-Extend Delay)
When motion is detected, the HIGH output stays active.
Each detected movement resets the delay timer, preventing false shutdowns.
🔧 Technical Specifications
- Working voltage: DC 2.7–12V
- Static current: <0.1mA
