SMART GROCER

Mechanical Engineering

This project focuses on design and implementation of Smart Grocer. It is a machine that dispenses bulk food items like pulses, nuts, rice, cereals, fluid etc to customers automatically. Large scale retailing is possible through this machines by placing the machine at convenient locations like bakery and public distribution shops etc. This reduces usage of plastics and malpractices at grocery shops. Machine contains three systems payment system, delivery system and storage systems. Separate bins are used as storage units. Payment systems contain cash mode and cashless are commonly used .Here cashless payment like RFID systems is used as payment option. LCD is used as displaying unit. In this machine there are different chambers for dispensing the items. Each chamber has one continuous rotation DC motor attached under it, when someone insert RFID card on machine and presses the button, then corresponding DC motor rotates and dispenses the items .it measures the quantity itself by the predefined value and the items is dispensed as per amount entered .Adruno uno is the used as microcontroller. It is the brain of the systems which controls all subsystems like sensor modules and data base systems that connected across it. This machine provides several advantages like plastic reduction saves human effort, money and time. It is more reliable .the system will bring more improvements in the future.
