What is touchfree automatic water faucet? An automatic faucet or water tap (also touchless faucet, hands-free faucet, motion-sensing faucet, electronic faucet, sensor faucet, or infrared faucet) is a faucet equipped with a proximity distance sensor and mechanism that opens its valve to allow water to flow in response to the presence of a user’s hands in close proximity.

How does automatic faucet work? The valve engages the flow of water through a rubber-like disc. When the sensor doesn’t detect a signal, the valve remains closed so no water will flow through the faucet. As the sensor detects motion, it sends a positive message to the solenoid valve, which pulls the valve open and allows water to come out.

When you want water on-demand with no mess, touchless faucets are the ideal choice. Some people prefer a touch faucet because it offers more control to the user. It is less likely to accidentally turn the faucet on or off when you have to physically touch as opposed to make a motion in front of it.

Do all touchless faucets need batteries? Certainly yes. Every touchless or automatic faucet needs a power source in order to work, though the power sources can vary. While some models get their power from dry-cell batteries, other faucets will use a low-voltage current from an AC transformer. Your sensor faucet requires batteries to power it on. The lifespan of a battery in a touchless faucet is dependent on the size and type of battery the faucet requires. Most popular type is using four (4) AA alkaline batteries or lithium batteries. Touchless faucets are powered by lithium batteries, which release power evenly and enable longer battery lifetime. Usually, touchless faucet batteries typically last about one to two years on average.
