Diseño de un caracterizador de medios isotermos basado en ESP32 y DS18B20 en el entorno de programación de Arduino

Abstract

This work presents the design of a low-cost device, suitable for the scope of the determinations that are carried out in the Facultad de Química of the Universidad de la República and the Instituto Polo Tecnológico de Pando allowing the qualification of isothermal media, with low-cost microcontroller boards based on the Arduino development environment. The device also allowed the simultaneous temperature readings at 9 points, and by connecting to the internet through its integrated Wi-Fi, the results were transmitted to Facultad de Química servers, where the telemetry is recorded and can later be downloaded for analysis. Simultaneously the data were sent to a dashboard that allows the reading of the measurements in real time. Being connected to the power supply and with a stable Wi-Fi connection, measurements can be taken 24/7 remotely. The device allowed the qualification of several isothermal media, reporting some representative values of the potential of this type of development.
