A portable device for detecting when undergarments are wet with urine comprises electronic disposable sensor means in contact with said undergarment, an electronic detector means activated by said sensor means, and an alarm means activated by the detector means, all chosen and constructed such that there is no energization of any part of the system until a wet condition is detected and such that there is no possibility of more than 9 volts of electric potential in contact with the human body, with the current generated by said potential not to exceed 10 microamperes.
