Working process
| When the user uses water, the water collection device starts to collect the water consumption, and converts it into the required electronic signal to the microcomputer module for measurement, and displays it on the LCD display module. |
| When the user's amount of water drops to a certain value, the microcomputer module will have sound alarm, prompting the user should take the card to buy water. |
| If the amount of water is exceeded, the microcomputer module will automatically close the electric control valve and cut off the water supply. |
| Until the user has inserted the paid IC card to restart the valve for water supply. |
