Description

Technical Field

[0002] Infrared switch, full name pyroelectric infrared induction switch, is an automatic control switch based on infrared induction technology. It realizes automatic control function by sensing infrared heat emitted from the outside world, and can quickly turn on various electrical equipment such as lamps, automatic doors, burglar alarms, etc. The main sensing device of infrared switch is human body pyroelectric infrared sensor. Any object in nature, as long as the temperature is higher than absolute zero q, always emits infrared radiation. The higher the temperature of the object, the smaller the peak wavelength of the infrared radiation it emits, and the greater the energy of the infrared radiation emitted. When a person enters the sensing range, the pyroelectric infrared sensor detects the change of the infrared spectrum of the human body and automatically turns on the load; if the person does not leave the sensing range, it will continue to be turned on; after the person leaves, the load will be automatically turned off after a delay. The combined infrared photoelectric switch is a device that combines multiple infrared photoelectric switches to achieve more complex detection and control functions.
