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. The infrared sensor switch utilizes human motion infrared rays as control signal sources. When someone enters the detection field, it will activate the controlled load. Accurate sensitivity: the smart motion sensor light switch is a digital intelligent automatic control product, which is highly sensitive and easy to use. When an object or person enters the sensing range, this PIR detector can automatically turn on, and it will automatically delay turning off after the person leaves, helping to avoid leaving lights 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 time delay (5 seconds to 6 minutes). When people enter the sensing range, the light turns on automatically; when they leave, it automatically delays shutdown, preventing conventional manual operation. Color: black Material: plastic Package Contents: 3 x Automatic motion sensors Note: Light reflection and different displays may cause the color of the item in the image to appear slightly different from the actual product. Measurement allowance is +/- 1-3 cm.
