Smart Water Quality Monitoring System using IoT

Abstract

Abstract: The normal method of testing or analyzing water is by collecting water samples manually and sending them to lab tests where they are tested for various chemical compounds consuming much time and manpower. This challenge can be overcome by using Internet of Things (IoT). In the proposed method, Temperature, pH value, Conductivity, Chemical Oxygen Demand (COD) and Total Dissolved Solids (TDS) of water samples are collected using respective sensors. A Microcontroller is interfaced with the sensors and data is forwarded to a Personal Computer (PC) for processing. The data is also stored on the Cloud using IoT based ThingSpeak. The resources involved in water quality monitoring are greatly reduced and the parameters are analyzed in real-time. The information is also sent to a smartphone or laptop/PC. This quick process is beneficial as it aids in analyzing and saving water bodies that are at the verge of becoming completely unusable.
