Touchless faucets, also known as sensor faucets or motion-activated faucets, use infrared sensors to detect hand movements and activate the flow of water without the need for physical contact. Here’s a general overview of how touchless faucets work:
- Infrared Sensors: Touchless faucets are equipped with infrared sensors located near the base or on the front of the faucet. These sensors emit infrared beams or pulses.
- Hand Detection: When you place your hands or any object within the range of the sensor, the infrared beams are interrupted, and the sensor detects the presence of an object.
- Signal Transmission: The sensor sends a signal to the faucet’s control unit or solenoid valve, indicating the need to turn on the water flow.
- Valve Activation: The control unit or solenoid valve receives the signal and opens an internal valve, allowing water to flow through the faucet.
- Water Flow: The water flows out of the spout and continues until the sensor no longer detects the presence of an object or until a pre-set time limit has been reached.
- Automatic Shut-off: Once you remove your hands or any object from the sensor range, the sensor detects the change and signals the control unit or solenoid valve to close the valve, stopping the water flow. Some touchless faucets also have a pre-set shut-off time to conserve water.
- Additional Features: Touchless faucets often come with additional features, such as temperature control. This allows you to adjust the water temperature using separate handles or buttons.
Touchless faucets offer several benefits, including improved hygiene, convenience, and water conservation. They minimize the risk of cross-contamination and the spread of germs by eliminating the need to touch the faucet handles with dirty or soapy hands. Additionally, touchless faucets can help conserve water by automatically shutting off when not in use, reducing unnecessary water wastage.
It’s worth noting that the specific mechanisms and features of touchless faucets may vary between different manufacturers and models. Always refer to the manufacturer’s instructions and guidelines for proper installation, maintenance, and troubleshooting of your specific touchless faucet model.
