The raw water from rain water, ground water, bore well water, lakes, river, is filtered and fed into water tank using pre-filter and make it use for drinking purpose. In this paper, it has been mainly focused to measure and maintain the TDS value, pH value range between 30 to 400 ppm and neutral respectively in water quality improvement and also it is used to make it suitable for drinking water purpose. The whole process is monitored by using an open source Internet of Thing (IoT) application. It works via internet or via local area network. To measure TDS value and pH value in the water, required sensors are connected with node MCU controller, depending upon sensor output the antiscalant liquid is injected using submersible pump to maintain the essential parameters in the drinking water. Through the android device the information is send to the cloud which is used to monitoring the values. The values are automatically updated for every 15 seconds by IoT application by representing the date and time of occurrence of the value of TDS and pH of drinking water.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
