Parts of an automatic faucet

Battery-powered automatic faucet

Any automatic faucet usually composes of four fundamental parts. Sensor, valve, power source, and spout


Sensors are devices that measure physical quantities. In automatic faucets sensors have to detect the presence of hands under the faucet’s spout. Three types of sensors in an automatic faucet. ultrasonic field sensor, an infrared detector, presence sensor.

Presence sensor

The presence sensor detects the presence of the hands under the spout.

If it’s there, a signal sends to the valve, which turns on the water.

As soon as the needle removes, so it stops water.

Ultrasonic field sensor

An Ultrasonic field sensor detects the movement of the hands under the spout.

Infrared sensor

Infrared light locates next to which an infrared detector place.

You know infrared light spots on the hand, which sends a signal to the infrared detector. The motion passes on the valve, and the tap turns on. It turns on after the hand removes.


Solenoid valves uses to control the flow of water in an automatic faucet. Solenoids valves are electromagnets. A rubber disk in the valves holds the water’s stream. Suppose the faucet sensor sends the positive signal to the valve.

The rubber disk pulls, and water pour out from the spray head. Whereas, the sign is negative, the rubber disk is pushed, and the valve is closed.

Power source

Every touchless or automatic faucet needs a power source. Some faucets are battery-powered, while an AC supply powers others. These battery-operated faucets are relatively cheaper than their competitors.
