! The 10mm open version of the interface is made of iron, and the 12mm open version of the interface is made of plastic. Please note this before purchasing. Human body infrared sensor Sensing distance / light intensity / power — adjustable Small size and high sensitivity 160-degree monitoring range 1) LUX switch adjusts day or night operation: A. When set to the sun position, the sensor operates continuously; B. When set to the moon position, the sensor remains inactive during daylight and activates automatically at night. 2) TIME switch adjusts the sensor delay time (8 seconds to 6 minutes) Delay time refers to the duration the sensor remains active after detecting motion and the person leaves the sensing area. 3) SENS switch adjusts sensor sensitivity. Adjustment is generally not required. If false triggering occurs and the light stays on, sensitivity can be reduced to the minimum setting.
