2 Pcs PIR Motion Sensor Human Motion Detector for Automatic Light Control and Home Security

2 Pcs Pyroelectric PIR IR Sensor Human Motion Detector for Automatic Switch Overview A pack of two pyroelectric passive infrared PIR IR sensors designed to detect human motion and activate automatic switches. These compact detectors are intended for integration into lighting, alarm, and automation circuits to provide reliable motiontriggered switching. Key benefits Motionactivated control: Detects moving heat signatures to trigger automatic switches without the need for manual operation. Simple integration: Works with a wide range of controllers, relays, lighting circuits, and alarm modules for easy retrofit or installations. Dualpack for coverage: Two sensors allow multipoint detection or backup coverage for hallways, entryways, and larger rooms. Passive operation: PIR technology senses movement without emitting signals, enabling lowinterference detection. Compact and lightweight: Small form factor fits into common housings and mounting locations for discreet installation. Main features and attributes Function: Passive infrared motion detection to drive automatic switching applications. Compatibility: Suitable for use with household and lowvoltage automation systems, DIY electronics, security modules, lighting drivers, and relay inputs. Size and form: Compact sensor modules designed for installation in panels, fixtures, or enclosures where small sensors are required. Construction: Standard PIR element mounted on a circuit board and housed to allow straightforward connection and mounting. Performance: Responsive to human movement with stable output for triggering switches and control circuits. Practical applications Corridor and stair lighting: Use the sensors to switch lights on only when people are present, improving convenience in multiroom paths. Security and alarm systems: Integrate into alarm control boards to detect unauthorized motion and trigger sirens or notifications. Closet, cabinet, and undershelf lighting: Install in small spaces to provide automatic, hands lighting when the space is entered. Installation notes Designed for electrical integration; follow standard wiring practices for the target switch or controller. Ideal for retrofit projects and custom automation builds where a compact passive motion sensor is required. Use two sensors to cover adjacent zones or to increase detection reliability in larger spaces. What makes this product stand out Practical twopiece set for flexible placement and multipoint detection PIR technology for passive, reliable detection with minimal electrical complexity Compact modules suitable for a variety of household and industrial automation tasks This 2 Pcs Pyroelectric PIR IR Sensor Human Motion Detector for Automatic Switch is a straightforward solution for adding motiontriggered switching to lighting, security, and automation projects.
