Compact motion sensing signal module designed for reliable presence detection and simple integration. Key benefits Reliable automatic switching: The module outputs a logic level while a person is within the sensing range and returns to a low level after a built in off delay when the person leaves. This removes the need for manual switching and reduces unnecessary operation of connected equipment. Accurate and stable detection: Internal digital signal processing provides strong resistance to interference and precise induction, helping to avoid false triggers and ensuring consistent operation. Simple installation and flexible integration: Small, lightweight design makes mounting quick and unobtrusive. The module provides standard logic level output for easy connection to control circuits or automation systems. Optional light sensitive control: A reserved position allows for photosensitive control to be added. This optional feature enables sensing only during daytime or when ambient light is strong, according to installation needs. Key features Sensing behavior: Outputs while presence is detected, automatically delays then turns off to output low after vacancy. Signal processing: Built in digital processing for improved anti interference performance and accurate sensing. Physical attributes: Compact size and light weight for easy mounting in tight spaces. Optional photosensor: Reserved position for light sensitive control to enable or disable operation based on ambient light. Typical applications Corridor and stairway lighting: Automatically switch lights on when someone passes and turn them off after they leave to improve convenience and reduce manual operation. Entrance and security triggering: Provide a logic level signal to entry control or alarm systems when motion is detected, and clear the signal after a delay when the area is vacant. Cabinet, closet, and display illumination: Integrate with lighting drivers or controllers to provide presence activated lighting that returns to low output when not needed. Installation and operation notes Designed for quick installation thanks to compact form factor and light weight. Connect the module output to any control circuit that accepts a or low logic signal. Use the reserved photosensitive position when ambient light based control is required. This module provides a straightforward presence sensing solution with accurate detection, stable output behavior, and an option for light sensitive control to match different installation requirements.
