Automatic Liquid Dispenser Vending Machine

Download Project Document/Synopsis



A vending machine is a machine mainly used for business, which dispenses certain products to the customers when they insert currency or coin inside the machine. Automated vending machines are in demand these days that make numerous tasks and activities easier and efficient. Such machines need minimal human intervention to do this job. In this project we demonstrate a Coin based Soap dispenser vending machine. Coin based soap dispenser is a liquid soap vending machine, basically the system consists of a coin acceptor module, a load cell assembly which is used to measure the weight of the container, whenever we insert a coin, the counter on LCD increases by 1 and depending upon how much quantity is to be dispensed we press the corresponding button (i.e. the 500ml and 1 litre) after which the water starts dispensing , the weight of the water is continuously monitored at once it is equal to weight corresponding liters then the pumps are stopped and the process is complete.
