Pre-Paid Water Meter System Using Smart Card Technology

To limit water waste, the system has been built to allow for the least amount of water loss possible. The memory IC has been employed as a smart card on which the recharging is done in this Prepaid Smart Card system for Water Supply. As the water passes through the pipe, the units on the smart card will drop. The solenoid valve will close the water supply when this unit hits zero. The microcontroller IC has therefore been in charge of the process. In order to properly utilis the available water, the notion of prepayment system is used. This system will assist the society in raising water awareness. Memory IC, Microcontroller, Prepaid, Recharge, Solenoid are some of the terms used in this article.
