Design and Evaluation of a Universal IoT Datalogger

Currently, monitoring systems in various fields rely on commercial technologies that can be costly and, more critically, lack integration with remote management solutions. These systems often present accessibility challenges for researchers and professionals who require data collection for in-depth analysis. In addition, the deployment of sensing devices within more complex networks can be difficult, hindering the scalability and effectiveness of these technologies. This work presents a flexible smart multitechnological datalogger based on an Internet of Things (IoT) structure that utilizes numerous Low Power Wide Area Network solutions, allowing remote analysis of the phenomenon and reducing the installation and management complexity. The designed system was developed at a lower cost than state-of-the-art dataloggers and tested in the hydric monitoring scenario. The results indicate that the system can sustain remote monitoring operations for a significant duration without frequent battery replacements, making it suitable for applications that require extended autonomous deployments.
