The circuit is as shown. It is composed of resistor type dew condensation sensor, electronic switch, relay control discharge fan circuit, birdsong phonation circuit, audio power amplifier circuit and AC depressurization rectifier circuit. RH is a resistor type dew condensation sensor, it is sensitive to the high humidity air, and it can detect whether the steam in the air will be dew condensation.
