Infrared faucets, also known as infrared taps, work by using infrared sensors to detect hand movements and control water flow without any physical contact. The sensor activates the water when it detects motion and stops it when the hands move away. This technology enhances hygiene, conserves water, and adds convenience, making it an excellent choice for homes, businesses, and public spaces. This article will explain how infrared faucets work, their benefits, and why they’re a smart investment.
What Are Infrared Faucets?
Infrared faucets are automatic taps that detect hand movements using infrared sensors. Instead of turning a handle, users wave their hands near the sensor to start the water flow. The faucet stops once the hands move away, reducing water waste and preventing cross-contamination.
Key Takeaways:
✔ No-touch operation – Uses infrared sensors to activate water flow.
✔ Water-saving – Automatically shuts off when not in use.
✔ Hygienic – Reduces the spread of germs in bathrooms and kitchens.
How Do Infrared Faucets Work?
Infrared faucets function through a combination of infrared sensors, solenoid valves, power sources, spouts, and waterproof connectors. Each component plays a crucial role in ensuring touch-free operation and water efficiency.
1. The Infrared Sensor
The infrared sensor is the core technology that detects movement. It emits infrared light, which reflects off an object (such as a hand) back to the sensor. The sensor then triggers the water flow. The detection range varies depending on the faucet model, usually between 5 to 20 cm, to prevent accidental activation.
2. The Solenoid Valve
Once the sensor receives a signal, it communicates with the solenoid valve, which opens or closes the water flow. The valve operates through electromagnetic force, which either pulls or pushes a diaphragm to allow or block water movement. Some high-end models include advanced solenoid valves with adjustable response times to customize the delay before water stops.
3. The Power Source
Infrared taps operate using either battery power (AA, lithium) or an AC adapter connected to the main power supply. Some faucets have a dual-power system, switching to battery backup in case of electrical failure. Battery-operated models typically last one to two years, depending on usage, while AC-powered options provide continuous operation without needing replacements.
4. The Spout
The spout is where the sensor, solenoid valve, and wiring are housed. High-quality infrared faucets are made from brass, stainless steel, or chrome-plated zinc, offering durability and corrosion resistance. Some spouts feature pull-out designs for added convenience in kitchen applications.
5. Waterproof Connector Cables
Since infrared faucets are often used in wet environments, they require waterproof cables to ensure reliable connections between components. These cables have an IP67 waterproof rating, making them resistant to moisture and humidity, which enhances longevity and safety.
Benefits of Using Infrared Faucets
- Improved Hygiene
Infrared faucets eliminate the need to touch handles, significantly reducing the spread of bacteria and viruses. This makes them ideal for public restrooms, hospitals, and food preparation areas, where sanitation is critical.
- Water Conservation
By only activating when needed, infrared taps prevent unnecessary water waste. Studies show that automatic faucets can save up to 70% more water than manual taps, making them an environmentally friendly choice.
- Energy Efficiency
Low-voltage infrared faucets consume minimal power, and some models come with auto shut-off features to conserve even more energy. Temperature-controlled versions also prevent excessive hot water usage, reducing heating costs.
- Durability & Maintenance
Because infrared taps have fewer moving parts, they experience less wear and tear than traditional faucets. However, regular maintenance is essential. Cleaning the sensor and checking for mineral buildup ensures smooth operation. Most modern models feature self-cleaning mechanisms to minimize maintenance.
Conclusion
Infrared faucets offer homes and businesses a modern, hygienic, and eco-friendly solution. They help reduce water waste, prevent germ spread, and add convenience. Pairing them with wall-mounted soap dispensers enhances hygiene and saves space. Thinking of upgrading? Check out this installation guide here.
