Design and Development of IoT Based Water Quality Measurement System

Water is an essential need for human survival and the quality of the water always affects human health. If water is contaminated its leads to severe diseases. For the same reason, we must monitor the quality of the water. We can determine the quality of the water by measuring its parameters like pH, Conductivity and Turbidity. This paper presents the idea about low-cost IOT based portable approach for water quality measurements system. Because of its low-cost approach, everyone can afford to use it to determine quality of water. Due to IOT (internet of things), remote measurement is possible. The signal conditioning of all three sensors uses the LMC 6001 IC in a different configuration and STM32F411RE microcontroller for the data acquisition and scaling of the data. SN8200 Wi-Fi module is interfaced with a microcontroller to send data on the cloud server. While doing the experiments all three sensors are calibrated against standard solution and relationship between temperature and pH is studied. All measured data stored on the cloud database and used for further analysis of water quality.
