Tdl2023usb Black PIR Motion Sensor Controller for LED Light Bars Key benefits Automatic motion activation: Builtin PIR human body infrared detector turns LED lighting on when motion is detected and off after inactivity, reducing the need for manual switching. Ambient light awareness: Integrated photosensitive sensor prevents activation in bright conditions, ensuring lights only operate when needed. Broad compatibility: Supports DC5V to DC24V input with native 12V operation for common LED light bars and LED strip systems. Simple installation: Standard DC connector and compact black housing make retrofit and installations fast and tidy. Reliable control for industrial use: Designed to work with industrial power supplies and LED drivers to provide stable on off switching in commercial and residential installations. What it does Detects human movement using PIR infrared sensing and switches connected LED lighting accordingly. Uses a photosensitive sensor to judge ambient light and avoid unnecessary activation during daytime or when lighting is already sufficient. Accepts a wide DC voltage range so it can be used with different LED light bars and power sources without additional converters. Compatibility and attributes Model: Tdl2023usb Black Voltage range: DC5V to DC24V, commonly used with 12V LED systems Connection: Standard DC connector for straightforward wiring Form factor: Compact black controller housing suitable for mounting inside fixtures, junction boxes, or behind panels Function set: PIR motion detection and photosensitive switch for automated lighting control Practical applications Under cabinet and closet lighting: Automatically illuminate work surfaces or storage areas when someone approaches, and turn off after use to save energy and reduce manual handling. Hallways, stairways, and corridors: Provide hands , motion activated lighting for safety and convenience in both homes and commercial buildings. Retail displays and warehouse aisles: Activate display or aisle lighting only when staff or customers are present, improving visibility while limiting unnecessary run time. Installation tips Use with compatible LED light bars and DC power supplies within the 5 to 24 volt range. Mount the controller where the PIR sensor has a clear field of view for reliable motion detection and where the photosensor can detect ambient light conditions. Verify connector polarity and secure connections before powering the system. This controller provides dependable motion and light sensitive switching for LED light bars, simplifying automation and improving the practicality of indoor and commercial lighting setups.
