DC 12V 5A PIR Pyroelectric Infrared Human Motion Sensor Module Summary A compact PIR motion detector module that senses human body infrared and provides a switching output for DC 12V systems with a maximum load of 5A. Designed for straightforward integration into lighting, alarm, and automation projects. Key benefits Reliable human presence detection using a pyroelectric infrared sensor for motiontriggered control. Direct compatibility with 12V systems and loads up to 5A, simplifying power and load management. Small, PCBmounted module for easy installation in enclosures, panels, or prototype boards. Reduces manual switching by automating lights and equipment, improving convenience and energy use. Simple wiring and clear function make it suitable for hobbyists, installers, and system integrators. Function and performance Detection method: Passive infrared (PIR) pyroelectric sensing of human body movement. Power requirement: DC 12V supply. Output capability: Switches loads up to 5A at 12V DC. Module type: Body motion sensor module for triggering external devices or control circuits. Compatibility Works with common 12V lighting circuits, relay coils, LED drivers, alarm inputs, timers, and microcontrollerbased systems. Suitable for retrofit or installations where 12V control is available. Physical attributes Compact PCB module designed for installation inside fixtures or control boxes. Standard electronic components and sensor element on board for reliable operation. Mounting and wiring are suitable for conventional electrical enclosures. Practical applications Automatic corridor and stairway lighting: turn lights on when a person enters a space and off when no motion is detected. Security and alarm systems: trigger sirens, cameras, or notification inputs when movement is detected near doors or windows. Energysaving controls for workshops, storage areas, and utility rooms where lights or fans should only run when someone is present. Installation notes Supply with stable DC 12V power and connect output to the load or switching device rated to handle up to 5A. Ensure sensor has a clear field of view for the monitored area and is mounted to avoid direct exposure to heat sources that may cause false triggers. Verify load type and wiring according to the load device requirements to prevent overloading. What makes this product stand out Straightforward, nofrills PIR detection optimized for 12V control applications with a 5A switching capability. Easy to integrate into both simple lighting projects and more complex automation or security systems without extensive circuitry changes. Package includes PIR pyroelectric infrared human motion sensor module, DC 12V 5A specification. This module is intended for nonmedical sensing and generalpurpose automation and security applications.
