gawa ka ng panel  [cone] na may diameter na 12 inches, tapos sa dulo kahit pass sensor[PIR sensor] ang ilagay mo, mabibili mo yan sa e-gizmo.. okay na yan... kapag may dumaloy na tubig ibig sabihin umulan na.. except lang kung may umihi sa panel mo.. hehehehe

or

use electrodes para madetect mo ang pagpatak mismo ng tubig sa rod, current on the rod changes when there is water in it...

Kung gusto mo makuha yung exact value nung rain pwede ka gumamit ng load cell para malaman mo yung weight nung water, or pwede ka mag-submerged ng dalawang plate sa loob ng container mo ( capacitive sensing ). Kapag nalagyan ng water yung container, tataas yung capacitance mo at dun mo malalaman na umulan nga at kung gaano kalakas ang ulan.

May problem sa capacitive sensing, kinakain yung isa mong electrode habang tumatagal.
