Do you know latest trend of touchless faucet for bathroom? It seems a technological miracle: Put your hand under the spout and water starts flowing like magic. But its inner workings are based on technologies that have existed for decades, cleverly adapted to a tap wrench. Contactless taps, also known as automatic faucets, have four main components: sensors, solenoid controlled valves, motor and pipe.
The sensor in a touchless faucet is usually located in the lip or the supplier base. By removing the hands, the sensor tells the tap off. Most sensors use a small faucets mounted infrared light with an infrared detector. When your hands come a few centimeters from the lips of the nozzle, the infrared light bounces off your skin to the detector, which sends a signal that activates the faucet valve. Some models of faucets use ultrasonic field sensor that turns on the faucet valve when his hands disturb the field.
