Real-time Water Quality Monitoring of Lakes using IoT based Remotely Operated Underwater Vehicle

Water degradation has become a critical theme of concern in recent years. Water is necessary for biological species survival and living activity is strikingly dependent on the quality of the water (i.e., physical, chemical, and biological aspects of water). The aim of the paper is to develop Internet-based Water Quality Monitoring System to determine the water quality parameters namely turbidity, PH, temperature etc. The developed model encompasses ESP32 Wi-Fi & Bluetooth Microcontroller with appropriate sensors and communication circuitry. The paper proposes a cost effective Remote Operated Underwater Vehicle which can monitor the parameters successively for prolonged period. The developed model is tested for three different cases and the parameters inferred are communicated through Thing Speak analytics platform
