Review of the Goals and Benefits of Monitoring Water Quality

Water quality is one of the most important variables affecting human life. Tests of the water’s purity must normally be done on the spot. If the area 
to be explored is large, it will be necessary to conduct tests at various sites. Repeated evaluations of the water quality will be challenging and time-
consuming. Therefore, a real-time monitoring system is required to protect the water and monitor its state in order to prevent contamination. The 
water quality is monitored and shown using environmental sensors, LoRa technology (Long Range) refers to a group of wide-area communication 
technologies that have better obstacle occlusion and longer signal propagation distances, and the Node-RED application. It entails the monitoring 
and collection of information on elements that have an impact on water quality, including climate, conductivity of electricity, pH, air pollution, and 
turbidity. The microcontroller utilized in the study processes the sensor data before sending it wirelessly to the database structure, where it can 
be seen on the Node-RED display the Node-RED dashboard and real-time water quality monitoring are both features of the IoT-based monitoring 
system.
