After the power is turned on, the controller will emit a coded infrared light wave to the front. After the light wave hits the human body, it will be reflected back and sensed by the receiving tube in the controller, and judged by the microcomputer in the controller. Immediately afterwards, a valve opening command is issued to the nozzle portion of the solenoid valve, and then the solenoid valve of the shower head portion is opened, and the nozzle is discharged. After the human body leaves the controller for a certain distance, the reflected light wave is weakened, and the receiving tube can not receive the reflected light wave. Immediately after the microcomputer judges, the valve is closed to the shower head, and the solenoid valve will automatically close and the water flow stops.Bathtub Faucets Suppliers from China
That is to say, when the human body enters the effective sensing range, the controller automatically sends a signal to open the switch of the solenoid valve or the electric valve, and automatically discharges the water. After the person leaves, the controller automatically sends a signal to turn off the switch of the solenoid valve or the electric valve. , stop running water. It eliminates the phenomenon of soaping in the bath and leaving the long flowing water when the bath is taken. The water saving effect is remarkable.
