Bus depots, public areas, colleges, big institutions, government offices, courts, holy places, hospitals, etc. and especially in highly populated countries. The system is so designed that no water wastage will be there by which we can conserve water.

RFID tag, Water management, resource allocation, Coin sensor, DC motor, 8051 microcontroller, vending machine.
