Dispositivo de aquisição e acompanhamento de dados modular

Abstract

In the era of technological development, every connection is an opportunity to transform a process, uniting technology and innovation to create intelligent solutions. This work presents the development of a data acquisition device with the ability to read multiple sensors in a modular way. Focused on data collection, the project uses the ESP32 microcontroller with FreeRTOS, featuring a main module that displays data to the user and secondary modules that collect data via a custom protocol. The main device uses an ESP32, an LCD screen, generation of a web page and an SD card integration to externalize data received from secondary devices that have an ESP32 and various sensors. All hardware is integrated with the use of circuit boards and receive a 3D case with easy coupling capability between devices. Tests were conducted to validate the concepts employed in the development of this project, where the modules remained connected for some days, collecting various data through their sensors. Additionally, the data visualization formats on screen, web page, and extraction via SD card were validated, confirming the concepts.
