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.
