An IoT Prototype for Water Quality Monitoring System with Case Study in NPIC Campus

Water is one of the natural resources that may be found in the environment. It is the most essential element of life. All living things, including humans, depend on water to survive, as do other species. Regretfully, water contamination has become a significant worldwide issue because of industrialization and irresponsible consumption. Moreover, low-quality water is poisonous to entire ecosystems due to its hazardous chemical and microbial contents. The issue is made much more dangerous by the lack of accessible tools for monitoring water quality other than costly laboratory tests. In this study, we developed an integrated system to measure water quality using the Internet of Things. Among the sensors, the system makes use of are Turbidity, pH (potential of hydrogen), TDS (Total Dissolved Solids), and water temperature. The embedded system is involved in this project as well. It will help with the establishment of wireless data transmission and sensor device detection. We employed LoRa technology alongside a cellular network ensuring effective communication. Firebase was utilized as the backend platform to securely store and manage the sensor data. The information can be tracked via a mobile or online application. Based on the sensor data, the water environment's quality was assessed and problems with the water's quality were anticipated to prevent the spread of contamination.
