Smart lock system for refrigerator

A project is to develop an APP operated automated refrigerator which has a smart lock and weighing sensors for 5 shelves (total 10 sensors). The idea is user will use his APP ( iOS and Android) to open the refrigerator lock by scanning QR code on the door. The scope of work is to complete the electronic hardware programming and integration and should be able to demonstrate its functionalities with iOS and Android APP. Mobile APP should have possibility to implement user registration User wallet will be charged based on input from Rasberry Pi, the raspberry pi will inform a database that at particular shelf weighs is reduced by XX grams which means the user has picked up YY product and it should be updated in Database and hence to User APP. More details will be given after first two milestones are completed. This project is only forcused on Electronic hardware and its circuitary and communication with computer. In another project APP work will be developed. Milestone 1: 1. Use of Raspberry PI recent version 2. Use of smart Lock 3. Use of 5/10 weighing sensors (load cell bridge) 4. Enclosure box for Rasberry Pi, 5. Project should consider the following hardware to be used: Refer Alibaba Website for those boughtouts and technical details 1. KERONG Smart storage Locker pcb control board for lock Model KR-CU 2. KERONG TCP/IP Centralized Control Board For Vending Machine Express Delivery Lockers Lock Control System Model KR-BU 3. KERONG Automatic Closing Electronic Fridge Locker Lock model KR-S98A 6. Programming of raspberry pi 7. Getting circuit done 8. Integration of 5/10 load cell bridge, smart lock, 9. Integration of Description of KR-CU see attached document. 10. Communication with PC in order to run the sequence. 11. Training to be done so i can run the same sequence with hardware in hand.
