DFRobot - DC 12V/24V Infrared Body Sensor Switch

DC 12V/24V Infrared Body Sensor Switch is an infrared-based motion detection controller designed to automatically manage power for connected loads. Using passive infrared sensing, this automatic motion-activated switch detects human presence within a 5–8m range and instantly triggers connected lighting or electrical equipment. The compact controller supports 5–24V power input and delivers the same voltage to the output load, enabling seamless integration with LED light strips, cabinet lighting, corridor lamps, and automation circuits. High sensitivity sensing, stable detection performance, and adjustable delay timing make this infrared motion sensing controller suitable for residential automation, commercial lighting control, and industrial equipment activation.

Note: Connect the load line first, then connect the power wire, and confirm that no short circuit exists between the wiring connections before powering on.

Reliable Infrared Motion Detection

This infrared human presence detector senses body heat movement within a 5–8 meter range and a 60° sensing angle, allowing automatic switching of connected loads. High sensitivity detection circuitry ensures reliable activation when motion occurs while reducing missed triggers. Such performance enables dependable use in lighting automation, security-triggered systems, and cabinet illumination setups where consistent detection response is essential.

Adjustable Delay Control

A built‑in timing adjustment knob located on the controller housing allows delay time configuration from 1 to 10 minutes. After motion is detected, connected loads remain active for the configured delay period. Once no human presence is detected for the set duration, the system automatically turns off the load. This adjustable timing function provides flexible energy-saving control for hallway lights, cabinet illumination, and automation systems.

Wide Voltage Compatibility and High Load Capacity

This motion-activated load switch supports a wide operating voltage range from 5V to 24V while maintaining identical output voltage to the connected load. The design supports currents up to 6A, enabling direct control of LED strips, lighting modules, and various DC-powered equipment. Efficient power management and low static power consumption make this automation control module suitable for continuous operation in residential and industrial environments.

Common deployment scenarios include automatic induction electrical equipment, bookshelf lighting, corridor illumination systems, LED strip control installations, security-triggered lighting, and industrial automation control environments where hands-free switching and energy efficiency are required.
