Abstract
Water pollution is a major global problem and the deterioration of water quality in rivers in many situations is becoming more widespread day by day, this causes a serious threat to all living beings and is eventually leading to the extinction of many aquatic species and others that depend on them. Therefore, with the advancement of Internet of Things (IoT) and Wireless Sensor Networks (WSN), monitoring the state of river water, for taking quick action to safeguard rivers becomes a pressing need, and is the main objective. An investigation was made into some existing IoT technologies and other related work to help achieve the objective of this project. In this paper we develop a low-cost solution based on Long Range (LoRa) to check in real-time, with specific sensors, some water parameters such as temperature, pH, conductivity, and turbidity. The data collected in a sensor node is sent via LoRa modulation to a gateway, where it is processed, forwarded to a local Message Queuing Telemetry Transport (MQTT) server, displayed on a local Node-RED dashboard, and alternatively it can be sent to the Internet. The developed prototype system is tested in a real scenario and proves that it can reliably monitor the water quality of a river in a reasonably sized area.
