IoT Based Water Quality Monitoring System

Technologies in various fields are developing and growing rapidly as science is getting better and more optimized. Most of this development are introduced to make the human life better and modernized with the cost of more environmental problems. Water pollution is one of the most alarming factors among various environmental pollutions. Fresh and clean water supply is the basing need for all of the living organisms in this planet. So, monitoring various water parameters in real-time like turbidity, pH, temperature, dissolved oxygen (DO) level, conductivity, etc. is becoming more and more important. In this paper, a modular and cost-effective real-time water parameter monitor system has been proposed. This system is equipped with various sensor nodes to monitor various physical and chemical parameters of water. And then the measured data will be sent to a secure IoT cloud server autonomously to be viewed on the internet using a web page. Also cloud computing method will be used which will compare gathered data with set-threshold value and result will be displayed to the user. Depending on this result a water-supply valve can be de controlled.
