The wardrobe sensor switch works by detecting the infrared rays of the human body, so the false alarm rate of the sensor switch human body sensor switch has a great relationship with the installation position and method, so how to install the wardrobe light sensor switch ?

　　First of all, what we need to know is that the sensing angle of the sensing device is generally 120°, and the sensing distance ranges from 1 to 8 meters. Its working principle is to automatically light up after sensing the infrared spectrum of the human body, and automatically turn off after the person leaves. In addition, if It is a photosensitive sensor that detects that it is daytime, the brightness is sufficient, and it will not light up. The working illuminance value of the light control setting can generally be adjusted within the range of 2LUX-2000 LUX. When the natural light intensity is higher than the preset level, the light Intensity will disconnect the sensor.

　　When installing, you need to measure the installation position first, punch holes, then fix the bottom of the sensor on the reserved position with expansion screws, and then connect the sensor body to the light according to the wiring circuit diagram given on the sensor, and then turn the body back The base is fine.

　　It should be noted that the induction switch cannot be operated with electricity when it is installed, and it needs to be energized after it is installed. Connect the human body induction switch to the power cord, the power cord is energized, and the human body induction switch starts to work. In addition, pay attention to the problem of load power, and it cannot be used in an ultra-power range. The first time the sensor works, it usually takes 30 seconds to 1 minute to test and warm up.

　　In order to ensure the maximum detection range, the sensor switch should be installed at a distance of more than 50 cm from the lamp, the ceiling installation height should be between 2.5-3m, and the wall installation height should be around 1.8-2m. Also note that when installing the human sensor switch , Should be far away from heat sources, air conditioners, refrigerators, stoves and other places where the air temperature changes drastically or high temperature heat sources.

　　In addition, in order to ensure the effectiveness of the inductive switch, there must be no other partitions such as furniture in the detection range. It is also not allowed to install in places with strong air currents such as doorways and windows.

　　If the light is on after the wire is connected, and the sensor switch cannot be controlled, there may be three reasons:

　　1. The positive and negative poles are reversed

　　2. The input and output are reversed

　　3. The working voltage does not match

　　At this time, you need to determine the voltage of the drive power supply and check whether the positive and negative poles are connected reversely. If the connection is reversed, connect it again.

　　The above is the installation steps of the induction switch. After installing the human body induction device, the home will be more modern and intelligent.
