Induction switch mainly includes infrared induction switch, microwave induction switch and ultrasonic induction switch. This article mainly explains the human body infrared intelligent induction switch, which is a switch that automatically starts when someone passes through the infrared induction detection area. The main device of the human body infrared induction switch is the human body pyroelectric infrared sensor. Pyroelectric infrared sensor of human body: the human body has a constant body temperature, generally at 37 ℃, so it will emit a specific wavelength of 10 μ M infrared, passive infrared probe is to detect the 10 emitted by the human body μ M or so. So is the infrared sensor switch good? What is the working principle of the infrared sensor switch? Here are the answers to the above questions

infrared induction switch definition

a switch that automatically starts when someone passes through the infrared induction detection area. The main device of the human body infrared induction switch is the human body pyroelectric infrared sensor. Pyroelectric infrared sensor of human body: the human body has a constant body temperature, generally at 37 ℃, so it will emit a specific wavelength of 10 mu; M infrared, the passive infrared probe is to detect the 10 mu emitted by the human body; M or so

the application scope of infrared induction switch is applicable to automatic lighting, ventilation and other purposes in corridors, corridors, warehouses, garages, basements, toilets and other places. It truly reflects the intellectualization of buildings and the modernization of property management

functional features of infrared induction switch

1. Automatic control products based on infrared technology. When people do not leave and are active, the switch is continuously on; After people leave, the switch will automatically turn off the load after a delay. When people arrive, the light will be on, and when people leave, the light will be off. It is friendly, convenient, safe and energy-saving

2. It has zero crossing detection function: contactless electronic switch, which extends the service life of the load

3. Apply photosensitive control, switch to automatically measure light, and do not induce when the light is strong

installation requirements of infrared induction switch

infrared induction switch works by detecting the presence or absence of infrared rays in human body. It is generally installed indoors. The false alarm rate of human body induction switch has a great relationship with the installation position and mode. The installation of human body induction switch should pay attention to the following points:

1. Do not operate with power on during installation, and then power on after installation

2. Do not exceed 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 inductive switch can be installed at the position of the original switch for direct replacement

4. When installing the human body induction switch, it should be far away from heating, air conditioning, refrigerator, stove and other places sensitive to air temperature changes

5. There shall be no partition screen, furniture, large bonsai or other isolators within the detection range of the induction switch

6. The switch should not be directly facing the window to prevent the disturbance of hot air flow outside the window and the walking of personnel from causing false alarms

7. Do not install the switch at the door, air duct and other places with strong airflow

editor's summary: the above is the principle of infrared induction switch, the relevant introduction of the installation requirements of infrared induction switch. The appearance of infrared induction switch can realize the switch directly by the temperature of human body! It's amazing! But there are also many requirements for the installation environment, which should be paid attention to
