120 Degree Pyroelectric Infrared PIR Motion Sensor Module 1 piece Clear benefits Reliable human body detection for motiontriggered systems. The pyroelectric PIR design senses changes in infrared radiation to detect moving people within a 120 degree field of view. Simplifies automation and security tasks. Use it to trigger lighting, alarms, cameras, relays, or control systems without complex setup. Compact and easy to integrate. The module format fits into prototypes, control panels, or custom housings and connects directly to microcontrollers and control circuits. Key features and attributes Function: Pyroelectric infrared motion detection for human presence and movement. Field of view: 120 degree detection angle for widearea coverage. Package: Supplied as 1 piece module for development or replacement use. Compatibility: Works with common microcontrollers, control boards, relay modules, lighting drivers, and alarm inputs. Suitable for use with standard 3wire or 4wire control schemes depending on system design. Size and form factor: Compact board module designed for easy mounting and integration into projects and enclosures. Materials and construction: Standard PCB with integrated PIR sensor element and mounting points for straightforward installation. Performance notes: Optimized to respond to human movement across its detection angle; ideal for indoor installations and typical automation tasks. Practical applications Automatic lighting: Install in corridors, stairwells, closets, or entryways to turn lights on only when someone is present. Security and monitoring: Use as a trigger input for alarm systems or surveillance cameras to capture movement events. Energy and occupancy control: Integrate into building automation, HVAC controls, or smart devices to enable occupancybased control and reduce unnecessary runtime. Installation tips Mount the module with a clear line of sight to the monitored area for results. Avoid placing the sensor directly facing heat sources, vents, or strong sunlight. Position at typical human height for occupant detection, or on ceilings for wider coverage depending on layout. Test orientation and placement during commissioning to confirm detection coverage meets project needs. What this module solves Provides a simple, readytouse sensor module for detecting human motion without designing a custom sensor assembly. Reduces wiring and programming complexity when adding presence detection to projects. Enables reliable trigger signals for automation, security, and energy management applications.
