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 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 transferred to the moon position, the sensor does not work during the day and automatically enters the working state at night 2) TIME switch adjusts the sensor delay time (20 seconds to 8 minutes) The delay time refers to the duration the sensor remains active after sensing movement and the person leaves the sensing area 3) LUX switch adjusts the sensor sensitivity. Generally no adjustment is needed If the induction is too strong and the light remains on, the sensitivity can be adjusted to the minimum position Fresnel lens, efficient refraction Flame-retardant casing, impact resistant Detection range: 160 degrees Detection distance: 6-8 meters (at 25°C) Ambient lighting: 2-2000 lux (adjustable) Working humidity: less than 93% RH Installation: open type (opening 10mm) Working voltage: AC85-265V Delay time: 8 seconds - 6 minutes (adjustable) Working temperature: -10°C to 40°C Installation height: 1.8m - 2.5m Color: black Material: flame-retardant ABS Size: 75 x 42 x 52mm Package Contents: 1 x sensor switch 1 x English manual Only the above package content, other products are not included Note: Light and different displays may cause the color of the item in the picture to vary slightly from the real thing.
