A REVIEW ON THE SENSORS FOR WATER QUALITY

  • Dr. Ezhilarasan G

Abstract

Terrestrial life can be carbon-based, but water makes up much of its mass. Every organism for saving life need access to clean water. The pressure on the water supply of our world has risen dramatically, demanding intervention in the control and purification of water, primarily due to human activities. In order to measure the issue and verify the effectiveness of remedial intervention, water quality sensors are necessary. This study summarises the most common criteria of chemical water quality and latest sensor application advances available for tracking. Special focus is put on technology that make reagent-free, low-maintenance, autonomous and continuous monitoring possible.In specific, chemical resistors and other electrical sensors are mentioned here, although there is also discussion of mechanical, optical and electrochemical sensors. The dynamics of chemical signal transduction in sensor components, which are in direct contact with the analyte, is also the subject here. The aim is to demonstrate the success and remaining obstacles for an audience of physicists and materials scientists in the production of sensor materials and designs.
