Practical motion sensor set: you receive 9 pieces of motion detectors in black colors, the load power of approximately 5W to 100W, and the working voltage is about DC 2.7 V-12V, reliable and reusable to use Accurate sensitivity: the smart motion sensor light switch is a digital intelligent automatic control product, which is highly sensitive and reliable to use; When an object or person enters the sensing range, this pir detector can be automatically turned on, and can be automatically delayed off after the person leaves, which can well avoid the situation of not turning off the light Infrared sensor switch utilizes human motion infrared rays as control signal sources, when one enters the detection field, it the controlled load at once. nergy-saving and low heat and low power consumption. Motion sensor turns lights ON automatically when motion is detected and OFF after a pre- time delay (5sec to 6minutes). People can enter the sensing range and can be automatically turned on,When people leave, they can automatically delay the shutdown, so as to prevent the conventional lamps from being opened., Weight: 2.42067563676 Pounds, Manufacturer: Deechate
