ABSTRACT:
A device for sensing the presence of liquids or other substances and warning of potential hazards. The device includes a mat which is constructed of metallized sheets. This mat may be cut to any size or shape on site. A monitor device is electrically connected to the mat and monitors a change in capacitance or resistance of the mat. Such a change is an indication of the presence of unwanted substace. The monitoring device may then either activate an alarm or turn off any electrical device as deemed necessary.
