A touchless water tap, also known as a touch-free or hands-free faucet, is a device that allows users to turn on and off the flow of water without physically touching the tap. This is typically accomplished through the use of sensors that detect the presence of a user's hands or other objects, triggering the flow of water.

Touchless water taps are becoming increasingly popular in public and commercial settings due to their ability to reduce the spread of germs and improve hygiene. They are also used in residential settings as a convenient and modern feature.

In addition to their hygiene benefits, touchless water taps can also save water and energy by automatically shutting off the flow of water when not in use. They may be battery-operated or connected to a power source.

Overall, touchless water taps offer a range of benefits and are becoming an increasingly popular choice for those looking for a more convenient and hygienic way to access water.
