This PIR motion sensor switch operates on a wide DC input voltage range of 5 to 24 volts, making it compatible with various DIY LED lighting projects and low‑voltage systems. The sensor is built with a compact ABS housing that houses a reliable passive infrared detection module. Its construction emphasizes durability and consistent performance, with a carefully sealed casing to minimize interference from dust or minor environmental factors. The internal circuitry is designed for stable triggering, supporting an occupancy‑sensing function that activates connected LED strips or other loads when motion is detected within the effective range.

The detection angle covers approximately 120 degrees, with an adjustable delay time that can be set to suit different usage scenarios, from corridor lights to cabinet illumination. The unit also features a USB interface for convenient power supply connection, which simplifies integration into existing USB‑powered setups or portable lighting modules. In terms of operational characteristics, the sensor switch offers a clean and responsive detection pattern, suitable for both permanent installations and temporary DIY arrangements. The infrared element is tuned to detect human body heat and movement, ensuring minimal false triggers from small pets or minor air currents under normal conditions.

The response time is quick, typically within fractions of a second, which helps maintain energy efficiency by activating lights only when occupancy is confirmed. The output can handle a load current of several amperes within the specified voltage range, supporting common LED strip lengths and other low‑power devices. The switch remains cool during prolonged operation, thanks to its low standby power consumption and efficient heat dissipation through the housing. This design contributes to long‑term reliability without the need for active cooling or frequent maintenance.

The product's straightforward wiring adds to its appeal for hobbyists and DIY enthusiasts. It includes clear terminal connections for power input, load output, and ground, along with the USB port for alternative power delivery. The sensor's mounting bracket allows easy attachment to walls, ceilings, or enclosures using screws or adhesive pads. The overall build quality reflects attention to consistent manufacturing standards, with smooth edges and a uniform finish that resists scratching.

The motion detection range is specified at up to 3 to 5 meters, depending on the mounting height and environment, which covers typical interior spaces like closets, hallways, or under‑counter areas. For users seeking an affordable automatic lighting solution, this sensor switch provides a practical balance between functionality and cost. It supports both normally‑open and normally‑closed configurations, adding flexibility for different control needs. The absence of complex programming or software setup makes it accessible for beginners while still offering reliable performance for more experienced builders.
