Salinity Level Indicator using IoT

Abstract

In recent years the groundwater has been contaminated with a lot of unwanted salts.So people started using purifiers which purifies the water which is sent to the water tank by using REVERSE OSMOSIS method.Reverse osmosis is a method in which a membrane will be present in the filter which will remove the unwanted salts present and reduce the hardness of water.This project is to check the level of TDS (using SENSORS) in the water which is going into the water tank and notify the resident with the level of TDS.If the level of TDS increases more than the normal level then the resident will be getting a notification on his or her mobile to change the filter which is being used in the water purifier.Till the filter in the water purifier is changed chlorine will be poured according to the pH level of the water present in the tank.The pH LEVEL is checked using the pH sensor. This entire process is done by using ARDUINO or Raspberry pi3.
