IoT based remote monitoring of water quality in tanks: Case of WASAC

Abstract

Water is considered as a basic need for human in their daily life. It is needed in different situations including, at home, in agriculture, in industry and manufactures, in hospital etc. To survive in a good life the quality of water should be monitored on highly level frequently and efficiently. Water pollution can be caused by different factors including large number of people who move from rural environment to urban (as long as the city get more rising number of people the waste management become an issue therefore these can provoke pollution in environment), more industries that provide different kind of waste, erosion etc. Unsafe water could lead to different diseases such as diarrhea, cholera, cancer. Generally, the quality of fresh water is described by chemical, biological and physical content and methods used in monitoring the quality of water usually were Water Sampling, Test Sampling and Investigative Analysis. But these methods are performed by the scientists in laboratories, and are found that they are slow. In this project we proposed an affordable system design for monitoring the quality of water remotely in tanks of WASAC by using technology known as Internet of Things (IOT) and this technology provides the required results in real time. A prototype was designed and developed with the use of hardware component together with the software program for implementing this project. The implementation of this project will carry a greater contribution to WASAC (Water and Sanitation Corporation) which is an organization company in the government of Rwanda (GoR). WASAC has different department but this project is applicable only on the side of water quality monitoring department. The system is built in a way that the technician can automatically receive a message through email about the state of water without going to the site.
