Speaking of water controllers, we will remember that many scenes in life are applied to water controllers, as a student editor, the most used is to use Mifare card to brush boiling water, the water controller can personalize water use according to the user's water needs, and provide effective solutions for water resources administrators, at the same time, it can provide a new idea for national energy conservation. This kind of thinking also promotes people's awareness of self-saving water.

The contribution of water controllers to energy saving and environmental protection is reflected in the reduction of waste of water resources, today, I will take everyone into the water controller, the water controller actually converts the cash currency into electronic currency through the server and stores it in the Mifare card. The principle of card swiping water controller is that when water users need to consume, they only need to put the Mifare card in the water controller swiping place, and the consumption amount can be deducted from it, receive water from the water outlet and record the transaction data and remaining amount to complete the entire transaction process.

The smart Mifare card water controller can individually set the ratio of water volume to time for each water-saving controller, which is transformed into a mode of calculating charges based on time, according to the customer's water pressure and pipe diameter, set the flow and time correspondence table. It can avoid waste, save and increase efficiency, and can cultivate the awareness of energy conservation and environmental protection of the water users, which is of great significance to both the unit and the society.

With the development of social economy, urban industrial and domestic water consumption is increasing, the current task of saving water is heavy, to further improve the scientific and technological content of urban water conservation, use scientific and technological means to promote the conservation of industrial and domestic water, so as to improve the level of urban water conservation to a certain extent. Mifare card water controller has considerable advantages for urban industrial domestic water, according to statistics, every year, industrial water is saved through energy-saving water controller to achieve emission reduction targets, this is also the effect of the promotion and application of water-saving and emission-reduction technologies, at the same time, it also promotes the continuous development of water-saving technology and promotes the vigorous development of a group of water controller professional technology enterprises.

In order to improve the management efficiency of users and realize the integration with other products, the FCARD can realize the seamless connection of one card pass. Fcard electronic water controller reflects the high standard and high quality of the product from its functional characteristics. Our water controller has innovatively added fine management, quota function, and offline and interconnected use, which has a certain control effect on the waste of water resources, and administrators can record consumption details through "fine management" so that consumers can inquire about their own usage.

The contribution of water controllers to energy conservation and environmental protection is not only in the conservation of water resources, but also in raising the awareness of energy conservation and environmental protection of the whole people and improving the quality of the whole people. When we talk about water controllers in the future, we can proudly stand on a more intelligent water-saving platform and go to the world.
