Product Description


What is the project?

An automated coin based water dispenser system is proposed which is used to dispense juice or water using motor and sensors. This system is also equipped with sensors to detect the presence of a glass to avoid wastage of the liquid dispensed from the machine.

How it works?

IR sensors attached to the microcontroller detects the presence of the glass to initiate the process. The microcontroller helps detect if the glass is present, a coin detector present detects the insertion of coins and sends the necessary information to the microcontroller. So, when a coin is inserted, the microcontroller sends the signal to the detector to detect the presence of the glass to dispense the water or juice. If the glass is removed while dispensing, the water flow will stop till the glass is detected again. This smart water dispensing system is the solution in water conservation.
