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-12V. Reliable and reusable for various applications. Infrared sensor switch utilizes human motion infrared rays as control signal sources. When someone enters the detection field, it activates the controlled load immediately. Accurate sensitivity: the 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, this PIR detector turns on automatically 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; when they leave, it automatically delays shutdown, preventing conventional lamps from being left on. Color: black Material: plastic Package Contents: 3 x Automatic motion sensors Note: Light reflection and different displays may cause slight color variations between the item and the image. Measurement allows an error of +/- 1-3 cm.
