After a hard day's work, the idea of simply sliding the plate under the kitchen faucet or putting your hand under it to turn on the kitchen faucet will bring pure happiness. Fortunately, this is no longer part of the magical fantasy. The touch-less kitchen faucet is popular for its unparalleled ease of use, convenience and accuracy.

More and more touch-less kitchen faucets on the market are sold at competitive prices, but before you decide to buy it, it is important to understand the science behind touch-less kitchen faucets and how they differ from traditional similar products.

When you use the motion sensor of these faucets, just wave your hand in front of the sensor to turn on the kitchen faucet. When buying touch-less faucets, please consider the number and location of motion sensors. These sensors are usually placed at the bottom, near the handle of the faucet or the top of the faucet. The wave sensor is usually placed on the top of the faucet to detect hand waves, and the ready sensor is usually placed near the bottom of the faucet to detect objects placed in the sink.

On the other hand, automatic faucets use presence sensors instead of motion sensors. They detect whether someone under the faucet opens it by hand. Once you remove your hand from the faucet, it will turn off the faucet. Most of these faucets use infrared light to detect the presence. When you put your hand under the faucet, this infrared light reflects off your skin and sends a signal to the kitchen faucet to turn on the faucet.

Some also use ultrasonic field sensors to detect your hand when it is damaged in the field. Once the sensor detects the signal, the water flow will use electromagnetic diaphragm valve or gear motor to open and close the valve. Diaphragm valves use rubber discs to control water flow. The valve is usually closed, but once a signal is sent, the solenoid valve opens it so that water can flow out of the water outlet. Touch-less faucets also provide you with manual operation options, you can use them like traditional faucets. The water temperature is adjusted by an independent control unit in the touch-less faucet. You need to adjust the temperature setting to the optimum temperature, and it will remain in this state until you change it.

Use the faucet handle to adjust the water flow in the faucet. Touch-less faucets are battery-powered or use AC power through an adapter, while other faucets give you the opportunity to operate in any way you want. If your faucet requires an AC adapter to power the motion sensor, then you need to have a power outlet near the sink.

Touch-less faucets are very useful when your hands are dirty or busy handling things, because they will automatically open by sensing your movements. In addition, they can prevent pollution caused by simultaneous exposure to different things. However, touch faucets are more popular than touch-less faucets because the hands-free sensor may be incorrectly activated due to a large amount of activity in the kitchen.
