With the development of science and technology, people's lives are becoming more and more intelligent and more humane. The infrared sensor switch is a good proof. When someone passes by the switch, the switch will automatically turn on. So, what are the requirements for the installation of this infrared sensor switch? Today, the editor will talk about the installation precautions of the infrared sensor switch.
Infrared sensor switch definition
A switch that is automatically activated when someone passes through the infrared sensing detection area. The main component of the human body infrared sensor switch is the human body pyroelectric infrared sensor.
Human body pyroelectric infrared sensor: The human body has a constant body temperature, generally at 37°C, so it emits infrared rays with a specific wavelength of about 10μm. The passive infrared probe detects the infrared rays emitted by the human body at about 10μm.
Precautions for the installation position of the infrared sensor switch
Infrared sensor switches work by detecting the presence or absence of infrared rays on the human body, and are generally installed indoors. The false alarm rate of the human body sensor switch has a great relationship with the installation position and method. The following points should be paid attention to when installing the body sensor switch:
1. Do not operate with power during installation, and power on after installation.
2. Do not use it beyond the power range.
3. The top-mounted human body induction switch should not be too high from the ground, preferably between 2.4-3.1 meters. The wall-mounted human body sensor switch can be installed in the original switch position and replaced directly.
4. When installing the human body sensor switch, it should be far away from the place where the air temperature changes such as heating, air conditioner, refrigerator, stove and so on.
5. There shall be no screens, furniture, large bonsai or other partitions within the detection range of the sensor switch.
6. Do not switch the switch directly to the window, to prevent the disturbance of hot air outside the window and the movement of people from causing false alarms.
7. Do not install the switch in places with strong air currents, such as doorways and air ducts.
