With the rapid economic development, the climate has become warmer in recent years, and countries around the world have begun to take various measures against climate warming, thus promoting the concept of environmental protection more and more popular, in the field of one card pass, water control designed for water saving machine, contribute to energy saving and environmental protection.

In today's wide range of application fields of water controllers, energy conservation and environmental protection is advocated by our country, and it is also the guarantee of sustainable development in economic construction, in the process of development, for the use of water, the enterprise adopts the enterprise water control management system not only to facilitate employees, but also to reduce enterprise expenses.

The water controller uses one card pass for card swiping management, and the automatic settlement of employee cards reduces logistics management personnel, thereby saving the company's manpower and material resources. In the past, employees often let go of the faucet to let the water flow out at will when bathing and daily water use, however, the application of the water controller in the corporate bathhouse can allow every drop of water to be wasted on the waster's water card, thereby eliminating the phenomenon of water wastage and reducing the management cost and economic benefit analysis of the enterprise. Make enterprise water automatic settlement more accurate and efficient. Reduce water waste and improve employees' awareness of water conservation and environmental protection.

The same use of environmentally friendly and water-saving products is becoming more and more the first choice for everyone, school as a place where collective water consumption is large, water-saving and environmental protection has highlighted its importance, therefore, how can we establish an environmentally friendly image for students? It is adopted by more and more schools.

For the southern region of my country, water resources are relatively abundant, while the northern region has been in a state of water shortage since ancient times, and how to use water resources reasonably has always been a problem that plagues us. At present, many schools have not installed Mifare card water controllers to provide free hot water to students. Although this seems to be a benefit to the students, it has produced various uncivilized phenomena that waste water resources. The school has been educating us to save resources and avoid waste. However, once under certain circumstances, it is difficult for people to really save water, statistics show that places with energy-saving water controllers can reduce water consumption by 70% compared with places without water controllers.

In the process of coping with global warming, energy saving and environmental protection, water controllers continue to play their due role, and integrate new technologies to continuously improve the water saving mode of water controllers, thereby making greater contributions to energy saving and environmental protection.
