| Summary: | The traditional method of water quality monitoring is time-consuming and expensive because it involves collecting water samples from various locations, transporting them to a laboratory, and analysing the samples. To address these limitations, a new system was proposed that used a LoRa (Long Range) sensor node to collect real-time water quality data. The data was then routed to a remote server via a LoRa Gateway. The remote server was built on a Raspberry Pi, and the user interface was designed with Grafana software. The system was capable of measuring pH (potential hydrogen), temperature, and total dissolved substance (TDS) and recording the data in a database that can be accessed via the internet. The system can last up to 3 to 5 days with the backup battery supplies. From our study, it is found that the developed system provides a dependable, real-time solution for water quality monitoring that can be employed in remote places and removes the requirement for manual water sample collecting and laboratory analysis.
