Sensor faucets are designed to be hygienic and convenient. They also conserve 70% of water compared to manual taps.
These devices work by detecting the presence of an object such as your hands or stack of dirty dishes. They use a small infrared light that bounces off your skin and back to the detector that turns on the faucet valve.
Detection of Hands
A Sensor Faucet is an automatic faucet that is equipped with a proximity sensor and a mechanism to activate the faucet's valve when your hands are in close proximity. Once the hand is out of range, the valve closes to stop water flow.
The sensors used in this technology are either IR or ultrasonic. The IR sensors use a small beam of light to detect your hands and send a signal to the valve to turn on the faucet.
The ultrasonic sensor is a bit more complex, but it does the same thing. Unlike the IR sensor, the ultrasonic one detects your hand in a very small field and instructs the valve to start the water flow.
Detection of Germs
When you use a sensor faucet, you don't touch the handles with your hands that are contaminated with germs. These faucets are a smart way to protect your family and guests from the spread of disease, especially during flu season.
The most common type of touchless faucet is motion-activated and uses sensors under the spout to detect human movement. These sensors send signals to the solenoid valve to activate the flow of water.
However, you can also get a sensor faucet that is more sophisticated in how it responds to your hand. This is because the sensor can tell the difference between a single touch and a more prolonged grab.
Similarly, you can find sensor faucets that automatically shut off after you wash your hands. This is a good option for restaurants and hotels, as it eliminates the need for re-handles to shut off the water.
Detection of Food Debris
A sensor faucet uses infrared lights to detect the presence of an object. These sensors are often located near the base or lip of the faucet. When something is detected, the light is sent to a receiver that activates the solenoid valve.
The technology can be found in both residential and commercial settings. In fact, it is commonly used in public restrooms and in kitchens where people frequently wash their hands or prepare food.
These faucets use a small infrared light to detect the presence of an object, then activates the solenoid valve to begin water flow. They can also be set to only turn on with a single touch.
Sensor faucets are a must have for any busy home or workplace. They are especially helpful in locations where germs can easily be transferred between people, such as hospitals or restaurants. They also make it easier for busy users to keep their hands clean. This may help prevent the spread of disease.
Detection of Water Waste
In addition to saving water, Sensor Faucets help save energy and reduce the spread of germs. They eliminate the need for people to touch the faucet with contaminated hands, which means they don’t have to be cleaned as often.
Most sensor faucets use infrared light or ultrasonic technology to detect movement. The signals of movement from the sensor activate a solenoid valve, which controls the flow of water. The polarity of the signal determines whether the solenoid engages a push or pull action to operate the valve.
Sensors are powered by a battery or an AC transformer, but they can also be hard-wired for power. Depending on the mode, this can provide a low-voltage current that allows water to flow, or it may use a latching solenoid valve that stays in the open position until it receives a push of power.
