The principle of infrared switch
Infrared: in the spectrum, the wavelength from 0.76 to 400 microns is called infrared ray, and infrared ray is invisible light. All materials above the absolute zero (-273.15 DEG C) can produce infrared rays. Modern physics is called thermal radiation. Medical infrared can be divided into two kinds: near infrared ray and far infrared ray.
The infrared sensor is developed according to the principle of infrared reflection. It belongs to a kind of intelligent water saving and energy saving equipment. The utility model comprises an induction water tap, an automatic hand drying device, a medical hand washing device, an automatic soap dispenser, an inductive urinal flushing device and an induction toilet.
