1. A system for detecting spills comprising:
- a plurality of electrodes disposed within a portion of a surface;
a resistance meter in communication with the plurality of rows of electrodes; and
a spill detection module executed by a processor in a processing device and in communication with a database, the spill detection module configured to;
detect a spill based on a change in a resistance value between at least two electrodes among the plurality of electrodes, the change detected by the resistance meter;
determine a location of the spill based on a known location of each of the plurality of electrodes;
determine a size of the spill based on a number of the at least two electrodes for which a change in resistance value is detected;
retrieve known resistance values from the database corresponding to a plurality of substances;
compare the resistance value detected between the at least two of the plurality of electrodes against the retrieved resistance values corresponding to the plurality of substances; and
identify a type of fluid spilled based on a comparison of the resistance value detected between the at least two of the plurality of electrodes and the retrieved resistance values corresponding to the plurality of substances.

Abstract
A technique for detecting spills is disclosed. A number of electrodes within a portion of a surface are connected to a resistance meter. The resistance meter detects a spill by measuring a change in resistance between two or more electrodes when a fluid is spilled over the two or more of the electrodes. The location of the spill can also be determined based on a known location for each of the electrodes. The size of the spill can further be determined based on a number of electrodes which measured a change in resistance due to the spilled fluid.
