📝 Description
The HC-SR312 PIR Motion Sensor Module is a compact, low-power infrared sensor designed to detect human motion based on body heat 🌡️. 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.
⚙️Key Features
🔹 Ultra-compact design
🔹 Low power consumption 🔋
🔹 Wide voltage support (2.7V–12V)
🔹 Reliable motion detection
🔹 Clean digital output
⚡ 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.
📊 Specifications
Operating Voltage: 2.7V – 12V
Detection Range: Up to 3 meters
Detection Angle: ~100°
Output: Digital HIGH/LOW
Power Consumption: Ultra-low
