π Description
The HC-SR312 PIR Motion Sensor Module is a compact, low-power infrared sensor designed to detect human motion based on body heat π‘οΈ. It senses changes in infrared radiation emitted by the human body and outputs a digital signal when motion is detected.
Thanks to its small size and wide voltage range, this sensor is perfect for embedded systems, battery-powered devices, and compact IoT applications.
βοΈKey Features
πΉ Ultra-compact design
πΉ Low power consumption π
πΉ Wide voltage support (2.7Vβ12V)
πΉ Reliable motion detection
πΉ Clean digital output
β‘ How It Works
The PIR sensor detects infrared radiation changes in its environment. When a human body moves within its detection range, the sensor detects the change and outputs a HIGH signal. When no motion is detected, it returns to LOW.
