For the issue of water pollution we need a critical implementation i.e., water pollution monitoring system by using IoT with the increase in the development of technology. The system monitors the parameter through processing, storing the data, and transmission. This system uses an Arduino board with few sensors, a Wi-Fi system, and a PC. The proposed system monitoring with sensor interfacing device using IoT and programmed with high speed embedded C programming language. Finally, the various sensors monitor the data and send it to the cloud can be viewed in the IoT platform using the Wi-Fi system.
