100% brand new and high quality Features: 1. Upgrade double sensor for faucet, two sets of sensing areas, two water modes, 0.25 second fast induction. 2. Drains water inductively by IR, reducing touch pollution. 3. Bottom sensor for short-term water needs - When the sensor enters the bottom sensing area (within a limited distance of 10 cm), the water began to flow out. When the sensor leaves, Water stops flowing out. 4. Side sensor meets water storage requirements - When the sensor enters the side sensing area (within a limited distance of 5 cm), the water began to flow out. The current lasts for three minutes, and the water remains flow out even if the sensory object leaves. If the sensor enters the side sensing area again during the water flow process, the water can be stopped at any time. 5. First-class water efficiency, energy saving and environmental protection. 6. Simple design style, adapt to various home styles. 7. 6 sets of adapters, meet your different needs.
