What is the principle of toilet induction flushing?

The working principle of automatic flushing sensor for toilet urinal is to realize automatic flushing and control the flushing volume by using infrared induction control and electromechanical combination. Infrared sensing toilet automatic flushing device adopts infrared reflection principle. Once a person's hand or body approaches the infrared region, the infrared emitting tube will emit reflection, and the infrared receiving tube will integrate the microcomputer into the circuit, process the signal and send it to the pulse solenoid valve.
