Practical motion sensor set: you will receive 3 pieces of motion detectors in black color. The load power is approximately 5W to 100W, and the working voltage is about DC 2.7V to 12V. Reliable and reusable for various applications. The infrared sensor switch detects human motion using infrared rays as control signal sources. When someone enters the detection range, it instantly activates the connected load. Accurate sensitivity: this smart motion sensor light switch is a digital intelligent automatic control product, highly sensitive and reliable. When an object or person enters the sensing range, the PIR detector automatically turns on and delays off after the person leaves, helping prevent lights from staying on unnecessarily. Energy-saving with low heat and low power consumption. The motion sensor turns lights ON automatically when motion is detected and OFF after a preset time delay (5 seconds to 6 minutes). When people enter the sensing range, the device turns on automatically and delays shutdown when they leave, improving energy efficiency. Color: black Material: plastic Package Contents: 3 x Automatic motion sensors Note: Only the items listed above are included. Light reflection and different display settings may cause slight color variations between the image and the actual item. Measurement error allowance is +/- 1-3 cm.
