Abstract
A gas sensor device to detect an analyte gas in an ambient environment includes a housing including an inner chamber and a port, a porous member through which the analyte gas transports in operative connection with the port to separate the inner chamber from the ambient environment, a sensor responsive to the analyte positioned within the inner chamber, a source of pressure waves positioned within the inner chamber, a sensor responsive to pressure waves positioned within the inner chamber; and circuitry in operative connection with the sensor responsive to pressure waves to relate a response of the sensor responsive to pressure waves to a state of blockage in the porous member.
