[0002] Human body induction switch is also called pyroelectric human body induction switch or infrared intelligent switch. It is an automatic control product based on infrared technology. When a person enters the sensing range, the special sensor detects the change of the infrared spectrum of the human body and automatically connects the load. If the person does not leave the sensing range, it will continue to be connected; after the person leaves, the load will be automatically turned off after a delay. The main component of the human body infrared induction switch is the human body pyroelectric infrared sensor. The human body has a constant body temperature, so it will emit infrared rays of a specific wavelength. The passive infrared probe works by detecting the infrared rays emitted by the human body.

It is inconvenient to quickly disassemble and remove the human body sensing switch after installation, and it is even more inconvenient to inspect and maintain the inside of the human body sensing switch. During the use of the human body sensing switch, the internal heat cannot be quickly dissipated, thus affecting the service life of the internal components of the human body sensing switch.
