? The principle of infrared induction switch explains the installation method of infrared induction switch.

The main device of human infrared induction switch is human thermal discharge infrared sensor. Human pyroelectric infrared sensor: The human body temperature is constant, generally at 37℃, so it will emit infrared rays with a specific wavelength of about10 μ m. The passive infrared probe works by detecting the infrared rays emitted by the human body. How about an infrared sensor switch? What is the working principle of infrared induction switch? The following is what I brought to you about the infrared induction switch. Let's have a look.

Principle of infrared induction switch

The main device of human infrared induction switch is human thermal discharge infrared sensor.

Human pyroelectric infrared sensor: The human body temperature is constant, generally at 37℃, so it will emit infrared rays with a specific wavelength of about10 μ m. The passive infrared probe works by detecting the infrared rays emitted by the human body.

The application scope of infrared induction switch is suitable for automatic lighting and ventilation in corridors, aisles, warehouses, garages, basements, bathrooms and other places. Really reflect the intelligence of buildings and the modernization of property management.

Functional characteristics of infrared induction switch

Infrared induction switch function 1, automatic control product based on infrared technology. People never leave, and the switch keeps turning on; After people leave, the switch will automatically turn off the load after a delay, and the lights will be on when people are away, which is friendly, convenient, safe and energy-saving.

Characteristics of infrared induction switch 2. With zero-crossing detection function: contactless electronic switch, extending the service life of load.

Functional characteristics of infrared induction switch 3. Application of photosensitive control, automatic metering switch, no induction under strong light.

Detailed explanation of installation method of infrared induction switch

Infrared induction switch works by detecting the presence or absence of human infrared rays, and is generally installed indoors. The false alarm rate of human body induction switch is closely related to the installation position and mode. When installing the human body induction switch, the following points should be noted:

Installation method of infrared induction switch 1 Please do not operate with electricity during installation, and then power on after installation.

Installation method of infrared induction switch 2. Please don't use it beyond the power range.

Installation method of infrared induction switch 3. The human body induction switch installed at the top should not be too high from the ground, preferably between 2.4-3. 1 meter. The wall-mounted human body induction switch can be installed in the position of the original switch and replaced directly.

Installation method of infrared induction switch 4. When installing the human body induction switch, you should stay away from places where the temperature changes are sensitive, such as heating, air conditioning, refrigerators and stoves.

Installation method of infrared induction switch 5. There shall be no screens, furniture, large bonsai or other partitions within the detection range of the induction switch.

Installation method of infrared induction switch 6. Don't aim the switch directly at the window to prevent the hot air disturbance outside the window and the pedestrian walking from causing false alarm.

Installation method of infrared induction switch 7. Do not install the switch in places with strong airflow such as doorways and air ducts.

The above is the introduction of infrared induction switch. If you want to know more about the infrared sensor switch, please pay more attention and provide you with more complete, detailed and updated information.
