Coin Based Water Dispenser System

Presentation
Coin Based Water filler System venture is produced for the clients to utilize coin worked mineral water framework. It comprises of a Coin box, coin sensor, water sensor, Micro-controller unit, Mineral water tank, pump engine and so on. The client can utilize Mineral water by embedding coins in the coin box. A coin sensor is associated in the coin box. As per the coin dropped in the coin box, the sensor sends flag to the small scale controller unit. 

Water Dispenser System

The miniaturized scale controller examinations the quantity of coins dropped in the coin box and appropriately it works the pump engine. The pump engine conveys the mineral water from the tank as per the legitimacy of the coin. In the event that the water in the water tank achieves least level, the miniaturized scale controller works a signal. In this way the tank can be filled promptly. The Micro-controller projects are composed in low level computing construct. The smaller scale controller utilized is AT-MEGA 328. This will be exceptionally helpful in ventures, houses, foundations and so forth.


Our framework chips away at the standard of coin discovery. When we embed the coin in the opening, it wills camera get the picture and think about by utilizing mat lab hear utilized the picture preparing by coin discovery. With a picture preparing get the coin picture utilizing cam period and look at utilizing mat lab. At the point when coin is gone through the space camera get picture and look at utilizing mat lab, heartbeats are created at the yield of picture preparing. 

It will pass yield flag to the controller ARM7 and as indicated by the yield flag controller begin for working. To begin with it will check coin what's more, distinguish, if there are think about the coin picture implies precise coin is embedded. Controller show "put glass "message on LCD. When we are put the glass under valve Then it will IR sensor actuate it will be passed flag to controller once more controller to pump, it will be exchanged on water pump. Furthermore, water will fall in glass.

Time is set for water pump. At the point when set time is over pump is exchanged of consequently. After that it will show message on LCD. T hen counter will increase for another coin. At the point when counter is flood and water level is low it will indicate coin box is full and level is low in plain view and, reset counter. Message goes to approved number by utilizing GSM.

WORKING
Coin based water filler takes a shot at the guideline of coin recognition. When we embed the coin in the opening, it will distinguish by the sensor we utilized. Here we utilized IR based opto-coupler for the coin sensor. With an opto-coupler, the main contact between the info and yield is a light emission. At the point when coin is gone through the opening Infrared light shaft is intruded on, heartbeats are created at the yield of coupler . It will passes yield flag to the miniaturized scale controller and as indicated by the yield flag smaller scale controller begin for working.

To begin with it will check intrude, if there are hinder on flag it implies coin is embedded. Microcontroller show " put glass "message on LCD. At that point it will exchanged on water pump. What's more, water will fall in glass. Time is set for water pump. At the point when set time is over pump is turned off consequently. After that it will show "much appreciated" message on LCD. At that point counter will increase for another coin. At the point when counter is flood it will indicate coin box is full, reset counter.
