You can make your own rain sensor using a small piece of stripboard as link attached:

Thanks for the suggestion, i try before this water sensor but it need some amount of water to detect as i consider one element which is when there is rain but not raining cat and dog but with small rain sometimes it cant detect. Is there any suggestion for more sensitive sensor?

i think u will need combination of sensors output to determine whether it is real rain or not. sometime, its raining but the sky still seems to be very clear.

Maybe this is the same project.
I used large strip board to detect really rain. :idea:
