An all-in-one cold and hot water sensor faucet use active infrared sensor technology that allows you to start the flow of water without touching the faucet. Instead, just place your hand in front of the sensor will start the water flow, and the water will stop when you take your hand away. There is a hot and cold mixer integrated inside the controller.

Kege can offer the whole solution, sensor circuit electronic design, infrared sensor eye shape and sizes, solenoid valve, control box and power supply design. With all these spare parts you can design your own touchless faucets also.


  • Touchless Motion sensor: Keeping the faucet handle on, wave the sensor without touch, water flows, wave again, water stops. Water stops automatically after 3mins continuously flow.
  • Water-saving: Water-efficient faucet reduces overall water usage without sacrificing water.
  • Easily replace the batteries without tools.
  • Power detection. Close the solenoid valve automatically when power failure or low power.
  • Low power indication: This may indicate it is time to replace existing batteries with new ones or there is not enough power going to the unit.
  • Sensor distance adjustable by a remote controller.
  • Healthy and Safe: with touch free kitchen faucet, it can prevent the spread of bacteria and germs. It’s not only time-saving, but also hygienic.

Active infrared sensor technology

Active infrared touchless sensors use the emission and reception of infrared beams to detect the presence and/or movement of objects or people in their field of detection. The technology is ideal for applications requiring a long and narrow detection range.

The solenoid valve integrated with hot and cold water mixer together in the faucet.

Touchless sensor faucets use infrared sensor technology that allows you to start the flow of water without touching the faucet. Instead, just placing your hand under the spout sensor, the sensor will give the solenoid valve a signal to open, then the water will start flow; When you take your hand away, the sensor will indicate the solenoid valve to close, then water flow will stop.

In the future modern smart homes, a touchless faucet is also one core part. They’re cool, for one thing, as their motion sensors always give you some sort of smart, modern techy feelings. Plus, a touch-free faucet keeps your fixture and bathroom clean, it’s a good hygienic choice and decreases the risk of contracting viruses and diseases.

ouchless sensor bathroom faucets need electricity for sure. Both the sensor and solenoid valve works need electricity power.
Normally three choices:
1. DC: 4xAA alkaline 6V batteries;
2. AC: use a transformer to transfer power from 220V/380V to 6V;
3. DC/AC:Both DC/AC models existed, firstly use AC power to work, if AC no power then DC start to work.

Below three reason for your reference, for more details please visit our blog HOW TO TROUBLESHOOT TOUCHLESS FAUCETS .

1. Battery issue: battery no power or battery installed in the wrong direction.
2. Sensor issue:  the sensor got damaged, surface not clean or the waterproof cable connection issue.
3. Solenoid valve issue: the filter in the valve blocked or the valve is damaged.
