Brand New and High Quality! The 10mm open version of the interface is made of iron, and the 12mm open version of the interface is made of plastic. Please pay attention to this before purchasing. Human body infrared sensor Sensing distance / light intensity / power- adjustable Small size and high sensitivity.<br><br>160 degree monitoring range. 1) switch is to adjust day or night work. A. When adjusted to the sun position, the sensor works all day; B. When it is transferred to the moon position, the sensor does not work during the day and automatically enters the working state at night. 2) TIME switch is to adjust the sensor delay time (2010sec~8 1min) The delay time refers to the time when the sensor leaves the sensing area after the sensor senses the person and the sensor delays the time. 3) The switch is the sensitivity of the adjustment sensor. Generally no adjustment is needed. If the inductive induction is too strong and the light is always on, the sensitivity can be adjusted to the minimum position.
