Abstract
A detector unit (1) which, in the presence of moisture, operates a remote alarm via a wire-less link is contained within a sealed liquid-impermeable housing (2). The unit is powered by electrical charge stored in a capacitor, which may be rapidly recharged by inductive coupling. Remote sensing electrodes (69, 70) are formed by depositing an electrically conductive ink onto a disposable moisture-absorbent tail (65).
