Overview

Module for retrofitting existing coffee vending machines to add remote monitoring capabilities. It was designed to monitor key parameters such as ingredient levels (coffee, sugar, cups), machine status, and error conditions. The module communicated these parameters to a central backend server via GSM connectivity, enabling real-time monitoring and alerts for maintenance personnel. This allowed proactive servicing of machines, reducing downtime and ensuring consistent availability of coffee vending services.

Technologies Used

• C / ASM
• GSM module
• PHP for backend
