Abstract
Water quality monitoring is an important aspect of water resource management, especially in remote areas where water resources are vulnerable to pollution and contamination. In recent years, solar power has emerged as a viable option for powering water quality monitoring systems in remote areas. This thesis presents the design and development of a solar power water quality monitoring system that utilizes TDS and temperature sensors, an ESP8266 microcontroller, and a 6V solar panel with a TP4056 module to charge a Li-Ion battery. The system is capable of transmitting data wirelessly to a remote monitoring station using the Blynk app, and the data is also displayed in real-time on an LCD. The first phase of the study involves the selection of components and design of the system. The TDS and temperature sensors are chosen based on their accuracy, range, and ease of integration. The 6V solar panel and TP4056 module are selected to provide power to the system during low light conditions. The second phase involves the integration of the components into a functional system. The TDS and temperature sensors are connected to the ESP8266 microcontroller, which processes the sensor data and transmits it wirelessly to a remote monitoring station. The solar panel and TP4056 module are connected to the Li-Ion battery, which powers the system. The third phase involves testing and calibration of the system to ensure its proper functioning. The TDS and temperature sensors are calibrated to ensure accurate readings. The fourth phase involves field testing of the system, which is deployed in a water body to collect water quality data continuously. The final phase of the study involves data analysis and visualization. The data collected by the system is analysed to identify any trends or patterns in water quality, and the results are displayed in an easy-to-read format on a dashboard. The system's output is also displayed in real-time on an LCD, providing instant feedback on water quality to the user. The Blynk app provides a user-friendly interface for remote monitoring of the system and access to the data collected. The system's use of solar power makes it a cost-effective and environmentally friendly option for water resource management. The system's ability to transmit data wirelessly and provide real-time monitoring through the Blynk app and LCD makes it an efficient and user-friendly option for water quality monitoring.
