Features: The light will be activated ON/OFF by auto PIR motion detection. motion sensor switch outdoor sensing distance / light intensity / power-on time adjustable.A.When adjusted to the sun-position, the sensor works all day;BWhen it transferred to the moon position, the sensor will work when not enough light and automatically enters the working state at night. 180 Infrared sensor switch utilizes human motion infrared rays as control signal sources, when one enters the detection field,will start the controlled load at once. Energy-saving and low heat and low power consumption. motion sensor turns lights on automatically when motion detected and off after a pre-selected time delay (5 seccond to 8minutes optional). 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. Occassion ,suitable for home ,office ,school ect. Specifications: Power Source: 110-240V/AC Detection range: 180 degrees Power Frequency: 50/60HZ Current: 4 A Detection Distance: 12m (
