Generally, an inductive switch generally refers to a human body infrared intelligent inductive switch, and is a switch which is automatically started when a person passes through an infrared induction detection area, and a main device of the human body infrared inductive switch is a human body pyroelectric infrared sensor. The human body has a constant body temperature, generally around 37 degrees, and therefore emits infrared rays having a specific wavelength of around 10 μm, and the passive infrared probe operates by detecting infrared rays having a wavelength of around 10 μm emitted from the human body. Infrared rays with the size of about 10 micrometers emitted by a human body are concentrated on the infrared induction source after being enhanced by the Fresnel filter. The infrared induction source usually adopts a pyroelectric element, the pyroelectric element loses charge balance when receiving the change of the infrared radiation temperature of a human body, charges are released outwards, and a follow-up circuit can trigger a switch to act after detection processing. The switch will be continuously switched on when the person does not leave the sensing range; after the person leaves or does not act in the sensing area for a long time, the switch automatically delays to close the load.
At present, infrared induction switches are mainly used for controlling switches of indoor automatic doors (such as medical doors in hospitals) in the market, and the defects of infrared induction are obvious and summarized as follows through market use summary and continuous feedback of customers: 1. when the temperature is high in summer (when the ambient temperature is close to the temperature of a human body), the infrared device is easily influenced by the temperature, and the induction distance is close; 2. if dust exists at the front section of the infrared sensing device, the sensing distance is obviously unstable, and the sensing distance is shortened; 3. the infrared sensor is particularly sensitive to light, and when sunlight or high-frequency lighting light irradiates the infrared sensor, the infrared sensor becomes abnormally unstable, and the sensing distance is short and long.
