Innovative Water Pen for Monitoring Water Quality

A water pen for free chlorine, PH & TDS Sensing

Objective

• The major objective of this project is to develop a device modelled in the shape of a pen for the electro-chemical testing of water quality. This water pen will help users to measure pH, TDS and the residual chlorine content in the water samples.

Description

• Most of the current electrochemical sensing solutions in the market rely on the usage of junction-based reference electrodes. This usage of reference electrodes reduces its lifespan when it gets exposed to the various contaminants in water. To solve this issue, we have designed a solution in the form of electrode which uses only two metal sensing elements. The POC sensing elements have been fabricated with lab level techniques and we are working towards further improvements for the same. The proposed model for the water pen is based on the data obtained from the first version of the sensing elements. We have filed a patent for this technology which will ensure that we will be the pioneers in this area to resolve this crucial problem.

Impact

• The data recorded with the water pen will be crucial to monitor fluctuations in the water quality. This pivotal data can be further used to train AI to make predictions based on water quality on the basis of region. The proposed water pen can also be exported or deployed with the help of international collaborators and will become a feather in our country's cap.
