Practical motion sensor set: includes 3 pieces of motion detectors in black color. Load power capacity ranges from 5W to 100W, with a working voltage of DC 2.7V to 12V. Reliable and reusable design. Infrared sensor switch uses human motion infrared rays as control signal sources. When a person enters the detection range, the connected load is activated immediately. High sensitivity: this smart motion sensor light switch is a digital intelligent automatic control device, offering high sensitivity and reliable performance. Automatically turns on when motion is detected and turns off after a delay when the person leaves, helping prevent lights from being left on. Energy-saving with low heat and low power consumption. The motion sensor automatically turns lights on upon detecting motion and turns them off after a preset time delay (5 seconds to 6 minutes). Lights turn on automatically when someone enters the sensing range and turn off after a delay when the person leaves, avoiding unnecessary power usage. Color: black Material: plastic Package Contents: 1 x Automatic motion sensor Note: Light reflection and different display settings may cause slight color variations between the image and the actual item. Measurement may vary by +/- 1-3 cm.
