3.7V-24V Mini PIR Motion Sensor Switch with Light Sensor Auto Day/Night Detection for LED Strip Light Bedside Wardrobe Lighting

This compact PIR motion sensor switch is built for smart nighttime lighting. With a built-in light sensor and passive infrared detector, it activates only in low-light or dark conditions—during daylight or bright surroundings, it stays inactive to prevent unnecessary triggering and save energy.At night, the sensor wakes up automatically. When motion is detected, the connected light turns on instantly; after movement stops, it switches off after a 30-second delay. There is no response when stationary or in daylight. The detection coverage is approximately 120° with a sensing range of 3 to 5 meters, making it ideal for stairs, hallways, entryways, closets, under-bed lighting, bike sheds, or low-voltage LED strip installations.Its miniature cylindrical body measures about 12mm in diameter and 33mm in length (mounting hole: 12mm). The package includes a mounting bracket/clip and screws for flexible installation. The three-wire output (red, yellow, black) offers clear connections. It supports a wide DC voltage range of 3.7V, 5V, 12V, and 24V, with a maximum load current of 3A. Recommended power ratings: below 15W at 5V, below 36W at 12V, and below 48W at 24V.Important:Do not cover the side with printed text. It must remain visible to ensure proper ambient-light recognition and reliable motion detection.
