The invention relates to a sensor unit for detecting the wetting of a diaper. Signals from the condensation sensor are used to control an audible alarm and/or musical chime unit. The signals of the moisture sensor, on the contrary, are used to control the ground connection of a musical chip. A sensor unit, which comprises two contacts, mounted on a circular housing base is placed on the interior of the diaper. In a preferred variant, both contacts are coupled to a common switchable evaluation unit, which utilizes the conductivity of moisture to complete a ground to the musical alarm. In an improvement of the invention, both contacts are integrated into a plastic waterproof sensor module.
