1. A method for detecting and classifying sensor data, comprising: processing data collected from an array of sensors; performing a statistical analysis of the data collected from the array of sensors, to obtain statistically analyzed sensor data; determining, based on the statistically analyzed sensor data, whether or not there a response signal has been generated from the array of sensors; and performing, if a response signal is determined to have been generated, a numerical pattern recognition on the data collected from the array of sensors, in order to categorize the data.
