Rain detector electronic circuit project


Posted on Feb 7, 2014

This rain detector electronic circuit project is an very simple alarm circuit, that will start an audio warning, if the liquid is present on the sense pad. This rain detector electronic circuit diagram is based on two transistors. When the sense pads conducts, Tr1 and Tr2 from an audio oscillatory circuit that will generate a pitch sound. Th
