Water is an important natural resource for all living organisms. Due to increase in population, industrial magnification and urbanisation, water gets contaminated these days. The aim of present study is to design a low cost and reliable system for the monitoring of real time water quality. This study includes monitoring of physiochemical parameters such as pH, Temperature, Turbidity and Total Dissolved Solids (TDS). Microcontroller based multi sensor system can measure the said parameters for detecting water contamination and incorporates communication technology for further processing and alerts. Data communication module can transmit the data received from system to intended user for making alerts regarding water quality. User can check the water quality information perpetually even from far away and he or she can take several safety measures to prevent health hazards. Facile design and low cost make this system captivating enough for large scale deployment.
