5 Pack RE200B 310V DC PIR Infrared Motion Sensors for Security Systems Product highlights Readytouse set of five RE200B PIR infrared motion sensors, ideal for expanding detection coverage or replacing multiple sensors at once. Operates from 3 to 10V DC, compatible with a wide range of alarm panels, lighting controllers, and lowvoltage control circuits. Passive infrared detection detects body heat and movement to provide motiontriggered output without active emission. Compact modules designed for easy mounting and wiring into existing security or automation installations. Practical for small projects and system maintenance where multiple identical sensors are required. Key benefits Simplifies installation and upgrades with a fivepiece pack for consistent performance across multiple zones. Broad voltage range allows flexible integration into many 3 to 10V DC systems without additional power conversion. Passive infrared design consumes minimal power and operates without emitting signals, suitable for discreet monitoring. Consistent model RE200B output and behavior reduce calibration time when deploying several sensors together. Function and compatibility Function: passive infrared motion detection. The sensor monitors changes in infrared energy and provides a motion output when activity is detected. Compatibility: designed for use in security systems, lighting control circuits, alarm panels, and DIY electronics that accept a 3 to 10V DC sensor input. Intended for standard indoor security and automation applications where PIR detection is appropriate. Performance and form factor Pack of five identical RE200B sensor modules for uniform response across multiple locations. Compact footprint for mounting in enclosures, panels, or behind fixtures where space is limited. Durable construction suitable for routine installation and integrated security equipment. Typical applications Home security: place sensors at entryways, corridors, and common areas to detect unauthorized movement and trigger alarm systems. Lighting automation: use sensors to automatically switch lights on in stairways, hallways, or storage rooms when motion is detected. DIY and commercial alarm projects: integrate into control panels or microcontroller projects for reliable motion detection across multiple zones. What you get Five RE200B PIR infrared sensor modules, each specified to operate from 3 to 10V DC and compatible with common lowvoltage security and automation systems. Simple installation tips Verify your control circuit accepts a 3 to 10V DC sensor input before connecting. Mount sensors where they have a clear line of sight to the monitored area and where direct sources of heat are minimized. Deploy multiple sensors from the pack to cover separate zones with identical sensor response and wiring. This product provides a practical, consistent solution for adding or replacing passive infrared motion sensors in 3 to 10V DC security and automation setups.
