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. This reliable and reusable infrared sensor switch utilizes human motion infrared rays as control signal sources. When someone enters the detection field, it will activate the controlled load immediately. 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, the PIR detector turns on automatically and delays off after the person leaves, helping to avoid unnecessary lighting. 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). It activates upon entry into the sensing range and automatically delays shutdown after exit, preventing conventional lamps from being left on.
