Comprised of many thermocouple elements, the SleepSense Disposable Thermal Flow Sensors produce a signal that is proportional to respiratory air temperature changes.  The signal generated provides a clear, reliable indication of respiratory airflow.

Internal battery and filtering circuits provide clean and reliable respiration signals to the system. The battery within 1415v2 should last at least two years of continuous use. The output may be connected to any AC channel on the recorder or the thermal-flow channel.
