1. Introduction of automatic soap dispenser
The principle of the infrared automatic soap dispenser solution is very simple. Its main body is divided into two parts: the host and the hand sanitizer. Among them, there is an infrared photoelectric sensor hidden in the foam outlet position of the main unit. When the hand reaches below, the infrared sensor sensor receives the signal, processed by the EN8F156 single-chip microcomputer, and controls the motor to extrude the hand sanitizer foam.
Application scenario: The infrared automatic soap dispenser is easy to use, can prevent disease transmission, and is suitable for homes, hotels, airports, customs and other places.
