Pack of three 12 volt PIR motion sensor timer controllers for automatic lighting control. Each unit uses passive infrared detection to turn lights on when motion is detected and off after a set interval using the builtin timer function. Key benefits Hands lighting: Automatically activates lights when motion is detected, eliminating the need to search for switches in the dark. Time control: Builtin timer function turns lights off after no motion is detected, reducing unnecessary runtime. Lowvoltage compatibility: Designed for 12 volt DC lighting systems for a wide range of applications. Multilocation convenience: Three sensors in one pack let you install automated control in several areas at once. What this product does Detects human motion using PIR technology and triggers connected lights. Includes a timer controller so lights switch off automatically after the preset delay. Intended for use with 12 volt lighting circuits and accessories. Practical attributes Quantity: 3 sensor controllers included. Voltage: 12 volt DC operation. Function: PIR motion detection with timer control for automatic on and off switching. Use case flexibility: Suitable for various lowvoltage lighting setups. Typical applications Interior of recreational vehicles and campers: Automate cabin, storage, and entry lighting in 12 volt systems to simplify nighttime use. Undercabinet and closet lighting: Provide motion activated illumination for kitchen cabinets, closets, and pantries so lights come on only when needed. Garages, stairways, and utility spaces: Add automatic lighting to areas where hands are often full or light switches are inconvenient. Installation and compatibility notes Designed for integration with 12 volt DC lighting circuits and lowvoltage fixtures. Check wiring compatibility and follow standard lowvoltage wiring practices when installing. Ideal for retrofitting existing 12 volt systems where automatic motion control is needed. What makes it practical Pack of three allows consistent coverage across multiple zones. Motion activation plus timer control reduces manual switching and helps keep lights operating only when needed. Straightforward function focused on reliable motion sensing and timed switching for lowvoltage lighting. Contents Three 12 volt PIR motion sensor timer controllers for lighting control.
