Makeblock mBuild PIR Sensor P3030034

The mBuild PIR Sensor (P3030034) is a module developed by Makeblock, designed to detect human presence by sensing infrared radiation emitted by warm bodies. It's commonly used in security systems, automated lighting, and interactive installations. Key Specifications: Detection Range: 3–5 meters Detection Angle: 80° (x-axis) and 55° (y-axis) Operating Current: 15 mA Working Principle: The PIR sensor utilizes a human pyroelectric infrared sensor as its core component, detecting changes in infrared light around 10 μm in wavelength. It responds to the movement of human bodies or warm-blooded animals by sensing variations in infrared radiation.
