Diseño e implementación de un dispositivo IoT y plataforma web para dispenso y gestión en máquina de bebidas calientes en establecimientos comerciales : Dispositivo IoT para medida del flujo de bebidas dispensadas.

Abstract

The commercial food and beverage services sector has been experiencing remarkable growth and a relevant digital transformation in recent years, following the end of the health pandemic that affected us. This is reflected in the growing demand for the consumption of hot beverages (such as coffee, tea, milk and their different commercial variants) in commercial premises; the measurement of consumption of these beverages is carried out manually, dispensing quantities established by the containers and charging according to the volume dispensed. In this context, this project presents an innovative solution to optimize the dispensing process and the recording of the amount of beverage that the customer consumes. The solution is carried out through the implementation of an IoT device intended to record consumption measurements of popular hot beverages such as coffee, tea and milk in commercial self-services. The development of the project followed a user-centered design methodology, which included contextual analysis, definition of requirements, design and implementation of the IoT device, and its evaluation in a simulated environment. The design and implementation of the IoT device includes the selection of the IoT architecture, the hardware configuration (flow sensor, RFID sensor and ESP8266 NodeMCU boards), the development of the code necessary for its integration, the configuration of a Wi-Fi wireless network and the configuration of an MQTT broker for data management. To verify the results of the measurement of hot drinks made by the IoT device, this was done by simulating a self-service drinks counter in a controlled environment."
