We all know that water is our precious resource. Our country has always been a water-scarce country. Water resources are not abundant, but water waste is very serious. We must know that when we are wasting water, there is no water to drink in many places. Waste is reflected in all aspects, such as the unturned faucet and so on. Since the emergence of sensor faucets, this problem has been reduced a lot. Now the faucets in public places are basically automatically sensored. The function of the induction faucet is also very extensive.
