Design and development of electro-chemical water quality sensor


It is essential to find out the concentration of impurities present in the contaminated water quantitatively to distinguish the different water samples. The principle goal of this research work is to develop and demonstrate the efficiency and capability of an electrochemical water quality monitoring sensor using cyclic voltammetric technique implemented with PIC16f877 microcontroller. To develop this advanced electro-chemical impurities sensing technique, a detailed analysis need to be carried out on different water samples. The experiment has been conducted on different water samples using the newly developed sensor and it could able to distinguish the water samples based on their corresponding voltammograms. The VIT tap water has got the highest current response of 0.04Amps for a voltage sweep of +/-2Volts indicating higher contamination level when compared to all other water samples.
Keywords: Electro-chemical sensor, cyclic voltammetry, voltammogram, potentiostat, water contamination.
