Comparison between NodeMCU ESP8266 and Uno R3 for Software Development using Ubidots

Abstract

The Internet of Things (IoT) refers to devices with the capability to collect, analyze, and communicate sensed data to users. This technology streamlines user observation and control of water quality, aiming to enhance measurement precision and overall water conditions through the integration of Ubidots. The motivation behind this project is to monitor water quality, comparing the effectiveness of the NodeMCU ESP8266 and Uno R3 systems. This project was into hardware and software development. In the hardware development, first part the sensor such as Total Dissolved Oxygen (TDS) value attached with Uno R3 and second part TDS sensor attached with NodeMCU ESP8266 was integrated. For software development, Arduino IDE programming is used to program the operation of water quality monitoring system. Furthermore, Ubidots software to ensure the real-time update of data collection from water quality monitoring system (WQMS). Finally, the recorded data will be uploaded simultaneously to be an analyzed and compared on the IoT platform. The result shows that the WQMS can fully function in different conditions of water and software development using Ubidots.
