5Pcs PIR Motion Sensor Module DC Powered Infrared Detector for Smart Security Systems

Pack of five DCpowered PIR motion sensor modules designed for reliable human body infrared detection in security and automation applications. Key benefits Ready to deploy: Five identical modules let you cover multiple zones or units without delay. Detects human presence: Passive infrared sensing responds to body heat and movement, providing a practical trigger for alarms, lighting, and automation. Easy to integrate: Compact PCB modules connect directly to lowvoltage DC systems and control inputs on alarm panels or microcontrollers. Flexible use: Suitable for security systems, lighting control, entry detection, and DIY electronics projects. What this module does Function: Passive infrared motion detection that senses changes in infrared radiation caused by human movement. Power: Designed for DC supply for compatibility with common lowvoltage control systems. Output: Provides a motion signal suitable for interfacing with alarm circuits, relays, digital inputs, and microcontrollers. Compatibility and integration Works with common security control panels, lighting controllers, and automation systems. Compatible with development boards and microcontrollers such as Arduino and Raspberry Pi when used with appropriate interfacing circuitry. Standard module form factor and wiring make it straightforward to add into existing installations or projects. Physical attributes and materials Compact PCB module populated with infrared sensor and supporting electronics for a small installation footprint. Standard threepin signal interface for power and output simplifies wiring and replacement. Durable electronic components suitable for indoor use as part of security and automation systems. Performance and practical considerations Sensitive to human body infrared and movement for reliable roomlevel detection. Fast response to motion events for timely triggering of connected devices. performance when mounted with unobstructed view of the monitored area and away from direct heat sources or strong airflow. Common use scenarios Hallway or stairway lighting: Automatically switch lights on when motion is detected and off after no activity is present. Entryway or doorway monitoring: Trigger alarms or cameras when movement is detected at an entrance. DIY security and automation projects: Use multiple modules to create multizone detection with microcontrollerbased systems or integrate into alarm panels for expanded coverage. Package contents Five PIR motion sensor modules suitable for DCpowered security and automation applications. Installation tips Mount modules with a clear line of sight to the monitored area and avoid pointing directly at heating elements or windows with direct sunlight. Verify DC supply voltage and signal wiring compatibility with the target system before connection. Add basic filtering or logic in the control system to prevent false triggers from brief stray heat sources. This pack provides multiple, easytoinstall PIR modules for practical human motion detection in security and automation setups.
