Design and Development of Smart Water Purification Level Tester For Visually Impaired Person

Abstract

In this project we introduce a smart device for visually impaired persons, which will helps them to determine the purification level of drinking water. Without water lives wont exists means that water is life. The lifestyles of visually impaired person or blind people are too much challenging compared to normal people. We cannot say that, nobody can find a trouble-ness day for them. Due to their blindness they are facing huge troubles throughout their life. Smart and mobile devices are always trying to reduce their trouble-ness. In this paper we present a smart device for them for determining the purity level of drinking water based on conductivity properties. With conductivity our device can measure the TDS (Total Dissolved Solids) value that can determine water purity level. For visually impaired people proper audio message incorporate to TDS value will be transmitted.
