Abstract
Information may be extracted from an array of relatively low sensitivity hazardous material sensors deployed, for example within a population center, by collecting identification information, such as video data, RFID data, proximity data, and IR data along with the hazardous material sensor reading. The identification information may then be used to identify objects in the vicinity of the hazardous material sensor at the time the reading was taken. By using identification data to identify an object, and then correlating sensor data readings for that object with other sensor data readings for the same object, as identified using previously collected identification information, a statistically more significant reading may be obtained for that particular object than would be obtainable by any one particular hazardous material sensor. Optionally the proximity of the object to the sensors may be used to weight the readings from the sensors.
