The network interface solution developed in this work proposes a generic IoT case study focusing on transmitting collected data to the cloud solving the local storage problem due to hostile microcontroller conditions in the field and loss of data while storing to an SD card. Aiming for a low-cost solution compared to ready-made solutions such as commercial datalogger modules, which are imported, costly and with data control and storage done via proprietary software. This commercial solution features low sensor scalability, low expansion flexibility, maintenance is restricted to the manufacturer and long cable distance needed for internet communication. The solution developed in this work focuses on a communication interface for the server which is based on an open source solution. It is also a free online solution with wireless communication to a cloud server via WiFi, highly scalable in regards to pluggable microcontrollers and sensors. Additionally, since it is a solution for the web end user, it is cross-platform (Linux, Windows, MAC OSX and Android) which allows easier end-user access to report queries, real-time data tracking and creation of triggers for the monitoring sensors. This proposal allowed for the configuration of a server on a Raspberry Pi using open source solutions like MQTT, InfluxDB and Grafana, in addition to carrying out the programming of microcontrollers responsible for the data transmission to the internet or ESP32. As a result, it was possible to carry out data collection from sensors and send data via ESP32 which validated the proposed solution.
