How the sensor tap works?

Aug 20,2024

A sensor tap, often found in modern faucets, uses laser sensor activation to detect when hands or objects are in proximity and automatically turns the water flow on or off. Here’s a basic rundown of how it works:

1. Sensor Activation: The sensor tap is equipped with infrared (IR) sensors or capacitive sensors. Infrared sensors detect the heat emitted by your hands, while capacitive sensors detect changes in the electric field caused by the presence of your hands.

2. Signal Processing: When the sensor detects an object (such as your hands), it sends a signal to a control unit within the tap. This control unit processes the signal to determine whether to activate or deactivate the water flow.

3. Water Flow Control: Based on the signal from the sensor, the control unit operates an electronic valve or solenoid valve within the tap. When activated, the valve allows water to flow through the faucet. When deactivated, the valve shuts off the water.

4. Power Source: Sensor taps are typically powered by batteries or plug, some can be connected to the electrical system of the building.

5. Additional Features: Many sensor taps have adjustable settings to control the water temperature and flow rate, which can be managed through controls located on the faucet or remotely via an app.

Sensor taps are designed to enhance convenience, improve hygiene by reducing the need for physical contact, and help conserve water by ensuring it’s only on when needed.
