HOW DO AUTOMATIC FAUCETS (TOUCHLESS TAPS) WORK?
Automatic faucets, also known as touchless taps, use a sensor system to detect your hands and turn the water on and off—without any physical contact.
🔹 1. Sensor Activation
A motion sensor, usually based on infrared technology, is placed at the base of the tap.
When you place your hands near the sensor, it detects the movement or reflected infrared light from your hands.
🔹 2. Electronic Signal Sent
The sensor sends a signal to a small device called a solenoid valve.
The solenoid valve is like a gate that controls water flow.
When it receives the signal, it opens the valve, and water starts to flow.
🔹 3. Automatic Shut-off
When you remove your hands, the sensor no longer detects any movement.
The signal stops, the solenoid valve closes, and the water automatically turns off.
🔋 Power Source
These taps are powered by:
Batteries, or
Electric current (plugged in)
🌡️ Temperature Control
Many touchless taps have a side lever or knob to adjust the temperature and water pressure.
In some cases, temperature is pre-set and not adjustable.
✅ Advantages
Hygienic – no touching means fewer germs.
Water-saving – water flows only when needed.
Convenient – easy to use, especially for children and the elderly.
