LoRa-based Measurement Station for Water Quality Monitoring: Case of Botanical Garden Pool

The advent of Internet of Things (IoT) has made easier to build number of applications. In fact, the remote monitoring or sensing has been facilitated by the IoT. A number of sensor nodes with a networking capability can be deployed in order to have an ad hoc or continuous monitoring system. However, physicists at UCAD's Faculty of Science still use traditional means to collect their water quality data from a pool in the faculty's Botanical Garden with on-site measurements. This pool is used for aquaculture and to study some aquatic species. In this paper, we present a water quality monitoring system through LoRa transmission. It's a low cost infrastructure composed of a remote station for real-time data collection and a web platform for visualization and exploitation. To evaluate the reliability and efficiency of the system, we perform some performance tests and the results are also presented.
