Abstract
The pad comprises a sheet of flexible insulating material carrying an array of conductive sensor strips on one surface. On the opposite surface of the insulating sheet are provided four conductive pickup strips, two at each end. One pickup strip at each end is connected through the sheet by metallic staples to the odd-numbered sensor strips, and the other two pickup strips are connected by staples to the even-numbered sensor strips. Thus, two sets of sensor strips are provided, and two connections are made to each strip in each set, and these connections are used to couple the pad into an alarm circuit. In a second arrangement, conductive tapes are used to connect together sensor strips and pickup strips. In use, the moisture being sensed makes an electrical connection between the two sets of sensing strips, thus activating the alarm circuit.
