IoT Interface Device for Sensing Arsenic in Contaminated Water

Water pollution is a serious problem in different parts of the world. In addition, water quality must be monitored to ensure that the water is provided safely for drinking and other purposes. Too high a concentration of Arsenic ions in drinking water is the cause of many health problems, including heart problems, neurological problems, etc. Water sampling and laboratory analysis are required for traditional water quality monitoring. In this paper, we discussed an IoT-based interfacing sensor device for sensing arsenic contaminants in water where IoT cloud computing networks enable the integration of a variety range of mechanical and electronic devices. A Node MCU device is used for data transmission which emphasizes on Wi-Fi-controlled interface devices and IoT-enabled communication protocol for the detection of water contaminants. This system is connected to an IoT cloud platform to store the data for analyzing purposes where Red-Green-Blue (RGB) color detection occurs by identifying the wavelength of contaminants. The system makes use of IoT to display the output in real-time for on-site and off-site monitoring via mobile phone. The system makes use of IoT to display the output in real-time for on-site and off-site monitoring via mobile phone, The major advantage of IoT technology is that it easily connects devices and stores the generated data in the cloud. With the help of command control systems, data can be used for appropriate applications to make human life easier and safer while considering Industry's impact. The acceptable limits set by WHO and the Bureau of Indian Standards for Arsenic are 0.05 mg/litres and 0.01 mg/l respectively. Therefore, a smart and intelligent device that can be used for measuring Arsenic content which is very necessary today to ensure the health of human life in society.
