PIR Infrared Sensor Module engineered for reliable motion detection and simple installation. Advanced digital signal processing delivers accurate detection of human movement while minimizing false triggers. The module outputs a level signal when motion is present and returns to low when the area is clear. Adjustable delay time from 0.5 to 200 seconds lets you tailor response timing for different applications. Key benefits Precise detection: Digital signal processing and finetuned sensing reduce false alarms and improve response to human movement. Flexible timing: Delay adjustable from 0.5 to 200 seconds adapts to short or long activation needs. Noise resistant: Builtin antiinterference design maintains stable operation in electrically noisy environments. Compact and discreet: Lightweight, small form factor with color options green or white allows unobtrusive placement. Easy to install: Simple wiring and mounting make the module suitable for both professional installers and DIY users. Main features and performance Motion output behavior: level output on detection, low output when no movement is present. Adjustable delay control: Set timing between 0.5 and 200 seconds to match your device or system behavior. Optional light sensing: Reserved position for an optional photosensitive control lets you enable daytime or brightlight only activation to save energy. Robust signal handling: Internal processing filters noise and reduces unwanted triggers without compromising sensitivity. Compatibility and use Works with common security panels, lighting controls, and automation circuits that accept a standard motion detector output. Small footprint fits into compact enclosures or tight mounting locations. Practical applications Indoor security: Trigger alarms or alert systems when motion is detected in hallways, entryways, or storage rooms. Automated lighting: Turn lights on only when movement is present and off after a set delay to conserve energy. Home and office automation: Integrate with timers, relays, or controllers to automate ventilation, signage, or auxiliary systems based on occupancy. Installation tips Mount in a location with a clear field of view of the monitored area and away from direct heat sources. Use the delay adjustment to prevent frequent switching in traffic zones or to keep devices active for required intervals. Add the optional photosensor when you want the module to operate only under specific ambient light conditions. A practical, reliable motion sensing module designed to reduce false triggers, simplify integration, and provide flexible timing and lightcontrol options for security and automation projects.
