IC555 can also be used in monostable configuration for this purpose.

its very sensitive.

just tie IC555 trigger input to 5 V supply through 1K resistor.

then make close gap between trigger input pin and grond connection. you can make cross hatch pattern (like found in calculator keypads)

to gnd     to trig input

 

when rain drop falls on such pattern IC555 gets trigger and its output becomes high
