When I moved to bangalore I faced skin itches and hairfall . After researching I found out in high chlorine in water was the reason these problems. So I created a web app to find Ph level of water with ardunio board , Wifi adopter and Ph sensor. With Ph level we can know is the water safe to drink or bath.Future idea of our product is to have website where people can review and rate the various food products and mentioning toxicity level in food .
