Practical motion sensor set: Includes 3 black motion detectors. Load power range: 5W to 100W. Operating voltage: DC 2.7V–12V. Reliable and reusable. Infrared sensor switch detects human motion using infrared signals. When a person enters the detection area, the connected load activates immediately. High sensitivity: This PIR motion sensor is a digital intelligent automatic control device. It activates automatically when a person or object enters the sensing range and deactivates with adjustable delay after movement ceases (5 seconds to 6 minutes), helping prevent lights from remaining on unnecessarily. Energy-saving design with low heat and low power consumption. Automatically turns lights ON when motion is detected and OFF after a preset time delay. Color: Black Material: Plastic Package Contents: 3 x Automatic motion sensors Note: Light reflection and display differences may cause slight color variation between the image and the actual product. Measurement tolerance: ±1–3 cm.
