A lot of water bodies around the world are suffering from severe contamination which poses problems to the marine life as well as to all those living around them. Such problem could be brought down by just monitoring the water body. So, this paper mainly aims on the development of a microcontroller-based water quality monitoring system by measuring various decisive parameters like pH and temperature. The performance of the device has been corroborated by considering various water samples like mixture of lemon juice and water, soda, bottled water, tap water and mixture of laundry detergent. The developed system is being observed to efficiently measure pH and temperature with a maximum relative error of 3.75% and 2.65%, respectively. The accuracy and robustness of the proposed system coupled with its inherent simplicity and ability to display real-time results on a self-designed website establish itself as a potent tool for water quality monitoring purpose.
