Paper Details

In India there is problem of safe drinking water therefore we are going to provide mineral water. Water hasbecome the most commercial products of the century. This may sound bizarre, but true. The stress on the multiple waterresources is a result of a multitude of factors. On the one hand, the rapidly rising population and changing lifestyles haveincreased the need for fresh water. If opportunity costs were taken into account, it would be clear that in most ruralareas, households are paying far more for water supply than the often-normal rates charged in urban areas. Also, if thiscost of fetching water which is almost equivalent. Water is the most important aspect of our life but what happens in thereal world is there is lot of wastage in water. So now we are proposing a system named "Water vending machine usingsolar energy" which provides mineral water in prescribed amount of litres for very low cost. In this system for paymentwe are using prepaid cards which eliminates the complications which were present in coin operated vending machine. Byimplementing water vending machine we eliminate the waste of water and provide good quality of water at low costusing digital payment. For this entire system we are using renewable energy source that is solar energy for powersupply. 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.
