Abstract—Vending machines play an important role in selling goods because they do not require a salesperson to service or track sales and can sell indefinitely until the goods run out.  To report the number of items sold and left in the vending machine, it is important to make the trip to the machine and print the report, and it is inconvenient for the vending machine administrator. Therefore, the present study makes use of IoT technologies to track inventory and sales data. The system used ESP32 microcontroller as a main controller and UC-15 module was used as the Internet connection. The system was tested for seven days with ten vending machines that had IoT-based sales reporting devices installed. Throughout the test, all data was transferred to a central server every two minutes, totaling 720 times each day.  From the results of the experiment, it was found that the data can be sent to the server with a success rate of 98.04%.  Twenty employees of Asia Vending Machine Operations Thailand were selected for the satisfaction study, and they were extremely satisfied with the sales report device.

Index Terms—IoT, reporting device, vending device.
