IoT-based Smart Water Management Systems

Abstract

Water is of major interest and especially nowadays, due to increasing pollution, the problem of its quality is becoming more and more important. One of the main areas affected by the low water quality are the agricultural crops which represent the beginning of the supply chain. This paper aims to create a monitoring system based on IoT technology that can assess water quality in real time. Thus, the data will be taken with the help of sensors located in the water basins as well as on agricultural land. Devices will have Wi-Fi connectivity and the data received from the sensors will be sent via the MQTT protocol (using TCP/IP) to a Cloud database where they will be stored and processed. The main application for this station will be based on the SWAM project which aims to make a robust, scalable and flexible platform through which farmers can see the causes of weak crops due to poor water quality. The novelty of the paper resides in the types of sensors employed and collected data, in the integration of blockchain technology and in the scalability feature that allows the communication between more such SWAM systems.
