Vending Machine Telemetry project to extract machine data (DEX, MDB, EVA-DTS) - specifically vending machine selection and successful dispensing information (additional payment information will be good but not absolutely required), and upload them via GSM shield to a FTP. Data transmission about general sales counters, cash counter, general test counter, selections tests counters, selections prices, and other sales informations;
events / errors on vending machine with code and generate time;
upload them via GSM shield to a FTP or HTTP.
Electronic button for filler in order to confirm full load of the machine at current date and hour.
Integrated display LCD with minimum 4 lines X 20 characters in order to see status of telemetry device (initialization / receiving data / transmiting data / full load confirmation OK )
Work offline capabilities are needed for entire system in the situation of no SIM signal. Other technical functions need to meet auto erase old files from SD card once storage capacities is reached and old files are confirmed to already exist in the server.
Detailed schematics with Arduino, GSM shield (or similar), hardware interface with vending machine (including drawing power from vending machine), and all other required associated components (with part number) needs to be detailed and provided, together with Arduino firmware code. All other required components or codes to make the project well functioning shall be provided as well.
The milestones shall include (1) schematics and code and (2) full payment will be released after the project is successfully tested and accepted as functional.
