Development of pH value detection sensor for water to detect and automate water neutralization process

Abstract

Water pollution is one of the severe problems that have crippling effect on public hygiene. This paper proposes a suitable method to detect and perform corrective measures using sensing components to aid maintenance of water quality. In the money conservative market like India, less importance is given for public hygiene and there is a general myth that any quality monitoring system would be costly and complex in its operation. Water is a universal solvent and in nature, it is never totally pure. No matter how for isolated, it is from sources of contamination, it will always have some chemicals. Gases or minerals in the air, soil, or rock are dissolved by the water. Some dissolved materials give water its characteristic taste, and “pure water” is generally considered to be flat and tasteless. Our main purpose is to identify and treat to remove unwanted constituents in the water and to make it safe or fit for a specific purpose in industry or domestic applications. We are making our system portable and compact, to process only upto a certain limit as it is a prototype. The development of pH electrode plays a major role for this research. Resistance is measured for various levels of water, where non-linear resistance identifies the pH value. Each individual liquid has a different resistance level for the pH. As resistivity is directly proportional to the current & voltage. The methodology presents a self-developed pH level indicator that measures pH level of the water. The end process gives quality water for people usage and indicates the same with its auto monitoring system.
