Automatic Faucet Advantages

An automatic faucet is a faucet equipped with a proximity sensor and a mechanism that opens its valve to allow water to flow in response to the presence of a hand or hand nearby. The valve closes its valve again after a few seconds or when it no longer detects the presence of hands. Most automatic faucets are powered by batteries and incorporate an active infrared sensor to detect hand movements.

Automatic faucets are commonly used as sanitary fittings in public toilets, especially at airports and hotels, where they are expected to reduce water consumption and reduce the transmission of diseases that cause microbes. They can also be found in some kitchens and washrooms in some private homes. Other uses include providing drinking water for pets or livestock, whereby the presence of an animal allows water to flow into a trough or a watering dish.


Automatic faucets have the advantage of closing automatically after hand washing, reducing water wastage. When installed in a home, sensor faucets reduce the need for parents to ensure that children have turned off the faucet. They can also benefit older adults and those with arthritis or other mobility-limiting conditions as there are no twist or pull handles. Their automatic shut-off mechanism also significantly reduces the risk of sink overflow due to an inadvertent or deliberate valve.
