sensor to detect water

[hasan_tech]

can anyone give any idea how to develop a sensor to detect type of water

a sensor to detect type of water

How many types of water are there?

Which ones do you want to detect?

Ocean water is salty and conducts a lot of electricity. My tap water conducts a little electricity. Distilled (pure) water does not conduct.

One method is to use test strips. (I know, not what you want)

to detect water

Hay, some one put water in my whisky!

tq to all members.. actually my project is development capacitive sensor to detect existing liquid, for example detect oil, detect water, detect sea. When sensor detect liquid, it will give data output at LCD

Which is not what you said in your first post:

When sensor detect liquid, it will give data output at LCD

What data will it give to the LCD?

Have a look here for a bit of discussion on oil/water detection using a capacitive probe.
