Sensor bathroom faucets work using infrared technology or capacitive sensing to detect the presence of hands. Here's how they function: 1. **Infrared Sensor**: Most sensor faucets use an infrared light-emitting diode (LED) and an infrared light detector. The LED emits a beam of infrared light, which is invisible to the human eye. When hands are placed under the faucet, the infrared light reflects off the hands and is detected by the sensor. This reflection triggers the faucet to turn on the water flow. 2. **Capacitive Sensing**: Some faucets use capacitive sensors, which detect changes in the electrical field around the faucet. When hands come close, they alter the capacitance, and the sensor activates the water flow. 3. **Control Box**: The sensor is connected to a control box, usually located under the sink. This box processes the signal from the sensor and controls the solenoid valve. 4. **Solenoid Valve**: The control box sends an electrical signal to a solenoid valve, which opens to allow water to flow. When hands are removed, the sensor no longer detects them, and the control box signals the solenoid valve to close, stopping the water flow. 5. **Power Source**: Sensor faucets are powered by batteries or an electrical connection. Battery-powered models are more common for ease of installation and maintenance. 6. **Temperature Control**: Some models have a manual or electronic temperature control to adjust the water temperature, often located on the side or under the sink. These faucets are designed to conserve water and improve hygiene by eliminating the need to touch handles, reducing the spread of germs.
