GSM Based Advanced Water Quality Monitoring System Powered by Solar Photovoltaic System

Due to growing environmental and water challenges, sustained availability of clean water is very important. For accurate monitoring of its drinking quality water, low-cost measuring system is required. In this work we propose one such solar PV based system utilizing Wireless Sensor Networks (WSN) technology for accurate water quality monitoring. Three sensors: (a) pH Sensor (SKU: SEN0169), (b) Turbidity sensor (SKU: SEN0189) and (c) Temperature sensor (DS18B20) are employed in the system hardware. These sensors are connected with Arduino, Global System for Mobile (GSM), and liquid crystal display (LCD) for the purpose of communication and monitoring respectively. These sensors measure the required parameters (pH, turbidity, and temperature) and forward it to Arduino which are then displayed on the LCD. The measured values are transmitted through the GSM for monitoring purposes. A solar panel is used power-up the system and autonomy is provided through a lead-acid battery This allows application of system in remote areas where grid is unavailable. The system can also have other applications in the agriculture systems, aquaculture systems, domestic systems and in small industrial setups.
