Automatic dry cell principle

The first type: it is automatically given for a period of time after induction. If it is not dried after a period of time, it needs to be re-sensed. Of course, if it is not taken by the time, it will be taken away, and it will continue to blow there; this is at McDonald's, cinema. The bathroom is more.

The second type: that is, the feeling is that there is such a way, after the hand is put on, it is sensed (blowing), and after the hand leaves, it goes to sleep; this is the use of our company's restroom.

Regardless of which of the above, it is achieved by means of infrared sensing. Note that it is not far infrared (infrared emitted by the human body) but near infrared.

The main components of the induction consist of an infrared emitting diode (infrared light with an emission wavelength of 850-940 nm) and a light-receiving (photosensitive) diode. After the hand is placed, it is equivalent to a reflector. After receiving the infrared light reflected by the hand, the photodiode triggers the control circuit to control the fan to blow.
