Here's how touchless faucets work:
*Sensors: Touchless faucets use infrared sensors, to detect the presence of a hand or other object in front of the faucet.
*Activation: When a hand put the hand in front of the sensor, the faucet turns on.
*Deactivation: The faucet turns off after when it no longer detects a hand.
Touchless faucets can be installed in homes and small businesses, and they can even be retrofitted to existing faucets.

AC and DC power supply, automatic shut-off valve after power failure
1. AC uses a 110-240V switching power adapter; DC uses 2AAA alkaline batteries, and the battery box is built-in.
2. The integration of the product makes it simple to use.
3. The valve will be automatically closed when the battery power is out or the power is removed for maintenance to avoid water coming out after a power outage.
Durable Material - The sensor water tap is made of solid brass with a chrome plating surface which is wear-resistant, anti-corrosion, and long-lasting.
Saving Water - Hands in sensor range, water flows and hands leave, water stops, reduces overall water usage without sacrificing water pressure.
Hygiene & Convenience - The touchless sensor sink faucet does not need to touch the handle so it can reduce bacterial cross-contamination in life, and if your hands are full of stuff or dirty, you can just put your hand in front of the sensor and free of opening the switch, more convenient and safer.
Low power alert: when the power is low, there are LED flashes to indicate replacement with new batteries.
