Résumé : As the main freshwater reserve in Senegal, Guiers lake is facing socio-economic and ecological challenges. For several years, Guiers lake has been threatened by various sources of pollution, particularly related to industrial, domestic, agricultural, and shing activities. Industrial activity results in the release of pollutants into the water which have detrimental effects on the environment and human health. One of the major challenges in water resource management is quality control, which involves acquiring some informations about water, such as temperature, turbidity, conductivity, pH, and many other parameters. the level of presence of these parameters in the water can give information about the type and intensity of the pollution. Many approaches have been developed to address the problem of water quality monitoring through the Internet of Things. The application of these different projects in a local context (Senegal) is di cult due to the logistics (internet coverage, etc.) and the cost of certain components. Looking at the Senegalese context, this work is identified as a case study of the application of IoT technologies and low-energy LPWAN transmission in water quality monitoring. In particular, we will be using LoRa transmission technology in the access layer because of the many advantages of spread spectrum modulation. The aim of this work is not only to clarify the potential application of IoT in the Lac de Guiers area, but also to answer an important question about the accuracy of IoT systems in measuring the physical and chemical variables of water.
