SENSOR NETWORK SYSTEM

摘要

A sensor network system that includes a sensor array having a plurality of sensor units that include a plurality of sensor elements, each sensor element configured to generate an electrical signal in response to a chemical environment in the vicinity of the sensor unit. The set of electrical signals generated by the sensor elements of the sensor unit represents a measured signature of the environment in the vicinity of the sensor unit. An analyzer is configured to extract the measured signatures of each sensor unit from sensor unit information signals and to detect a presence and concentration of one or more of the gases of interest based on the measured signatures.

1. A sensor network system, comprising:
a sensor array, the sensor array comprising a plurality of sensor units, each sensor unit comprising:
a plurality of sensor elements, at least some of the sensor elements in the sensor unit sensitive to at least one gas of interest and being different in some functional respect from other sensor elements sensitive to the gas of interest, each sensor element configured to generate an electrical signal in response to a chemical environment in the vicinity of the sensor unit, the set of electrical signals generated by the sensor elements of the sensor unit representing a measured signature of the environment in the vicinity of the sensor unit;aggregation circuitry configured to aggregate the electrical signals of the sensor elements into a sensor unit information signal; andcommunication circuitry configured to wirelessly transmit the sensor unit information signal to an external receiver; at least one base station communicatively coupled to the sensor array and configured to receive sensor unit information signals from each of the sensor units of the sensor array; and an analyzer configured to extract the measured signatures of each sensor unit from the sensor unit information signals and to detect presence and concentration of one or more of the gases of interest based on the measured signatures.
