How does a touchless faucet work? – All you need to know

The touchless faucet is an electronic kitchen and bathroom fixture that uses motion sensors to automatically turn on the water flow whenever it detects a person’s hand. In the kitchen, a touchless faucet can save you from having to turn on the water manually. While in the bathroom, it will save you from having to touch the handle with dirty hands and spread germs and bacteria.  The technology behind these touchless faucets is quite simple. The sensor in the faucet detects any object that comes within a few inches of its sensor. When it detects something, it automatically turns on the water flow from your sink and starts running for a certain time.

How does a touchless kitchen faucet work?

Even though all touchless faucets have the same technology. There is a slight difference between touchless kitchen faucets and bathroom faucets.Touchless kitchen faucets have several components that work together to trigger the flow of water when you wave your hand in front of them.

1. Sensor

This is the part of your touchless faucet that senses when you wave your hand in front of it and then triggers the water flow. It also has a timer that shuts off after a few minutes so it won’t waste any water if you don’t want to use it anymore.

2. Solenoid Valve

This is another part of your touchless kitchen faucet that controls how much water flows through it at any given time by opening or closing an electrical circuit. When you wave your hand in front of the sensor it will send an electrical signal down through the solenoid valve which makes it open or close the water flow.

3. The Handle

In addition to controlling the water pressure, the handle also controls the water temperature. By moving the handle, you can choose between cold and hot water. Most faucets utilize a cartridge that directs the water flow. Newer models, such as those from Moen, use electronic control systems.

4. Power Source

The power source can be as simple as batteries or an electrical outlet that powers up the sensor and solenoid valve. Without electricity, these devices will not automatically turn on when they detect movement nearby.
