  "textContent": "A pressure sensor module includes a pressure sensor configured to periodically measure an internal air pressure within an enclosure and generate a sensor signal having plurality of sensor values; a signal processing chain for conditioning the sensor signal to generate a plurality of conditioned sensor values; a memory configured to store each of the plurality of conditioned sensor values; and a processing circuit coupled to the pressure sensor via the signal processing chain for receiving a current conditioned sensor value and coupled to the memory for receiving a previous conditioned sensor value. The processing circuit is configured monitor for a fault, including calculating a delta pressure value between the current and previous conditioned sensor values, comparing the delta pressure value to a pressure threshold value, and triggering a diagnostic of the signal processing chain if the delta pressure value is greater than the pressure threshold value.",
