Abstract: A gas sensor device includes a sensing element including a heating element and electronic circuitry in connection with the heating element. The sensing element forms a resistive element in a circuit of the electronic circuitry. The electronic circuity operates the sensing element in a trigger mode via a pulsed energy input to the heating element at a first duty cycle and in a primary mode via a pulsed energy input to the heating element at a second duty cycle, which is greater than the first duty cycle. The electronic circuitry is further configured to measure a response of the sensing element over time during each pulse of a plurality of pulses of the pulsed energy input. The primary mode is entered upon measurement of a value of a response at or above a threshold value in the trigger mode of operation.

Abstract: A gas detection device for detection of one or more gas analytes in an environment includes a housing including an inlet via which gas to be sampled from the environment enters the housing, a control system within the housing comprising a processor system and a memory system in communicative connection with the processor system, and one or more gas sensors within the housing in fluid connection with the inlet and in communicative connection with the control system. Each of the one or more gas sensors is independently responsive to one of the one or more gas analytes. The control system is configured to control flow rate of gas from the environment through an accessory device assembly including one or more accessory devices in fluid connection with the inlet on the basis of data for the accessory device assembly in fluid connection with the inlet.

Abstract: A method of detecting at least a partial blockage in a porous member separating a first volume from a second volume or inner chamber of a device includes emitting pressure waves within the inner chamber by changing a volume of the inner chamber, measuring a response via a pressure sensor responsive to pressure waves positioned within the inner chamber, and determining if at least a partial blockage is present in the porous member based upon the response of the pressure sensor.

Abstract: A system for detecting an analyte gas in an environment includes a first gas sensor, a first contaminant sensor separate and spaced from the first gas sensor, and electronic circuitry in electrical connection with the first gas sensor to determine if the analyte gas is present based on a response of the first gas sensor. The electronic circuitry is further in electrical connection with the first contaminant sensor to measure a response of the first contaminant sensor over time. The measured response of the first contaminant sensor varies with an amount of one or more contaminants to which the system has been exposed in the environment over time.

Abstract: A combustible gas sensor for detecting an analyte gas includes a first element including a first electric heating element, a first support structure on the first electric heating element and a first catalyst supported on the first support structure and electronic circuitry in electrical connection with the first element. The electronic circuitry is configured to provide energy to the first element to heat the first element to at least a first temperature at which the first catalyst catalyzes combustion of the analyte gas and to determine if the analyte gas is present based on a response of the first element to being heated to at least the first temperature. The electronic circuitry is further configured to apply an interrogation pulse to the first element in which energy to the first element is increased or decreased to induce an associated response from the first element.
