WATER VENDING MACHINE USING SOLAR ENERGY

Abstract

In India there is problem of safe drinking water therefore we are going to provide mineral water. Water has
become the most commercial products of the century. This may sound bizarre, but true. The stress on the multiple water
resources is a result of a multitude of factors. On the one hand, the rapidly rising population and changing lifestyles have
increased the need for fresh water. If opportunity costs were taken into account, it would be clear that in most rural
areas, households are paying far more for water supply than the often-normal rates charged in urban areas. Also, if this
cost of fetching water which is almost equivalent. Water is the most important aspect of our life but what happens in the
real world is there is lot of wastage in water. So now we are proposing a system named "Water vending machine using
solar energy" which provides mineral water in prescribed amount of litres for very low cost. In this system for payment
we are using prepaid cards which eliminates the complications which were present in coin operated vending machine. By
implementing water vending machine we eliminate the waste of water and provide good quality of water at low cost
using digital payment. For this entire system we are using renewable energy source that is solar energy for power
supply. The heart of the system is PIC16F877A micro controller and to read the prepaid cards there is RFID reader.
This system is applicable in railway stations, bus stops and crowded places.
