Abstract
A moisture presence alarm system has a sensor system which extends over an area to monitored and a detector device which receives signals from the sensor system. This has spatially separated conductors in contact with a moisture absorbent material. The position of the leak is determined by selective interrogation of pairs of conductors. The conductors may be in an orthogonal matrix (A1 . . . X1 . . . A2 . . . X2), each conductor (10,11) being associated with a moisture absorbent strip (12,13).
