Using a piezo-electric crystal, the respiration sensor converts chest or abdominal respiration motions to a small analog voltage that provides a clear, reliable indication of respiration waveforms. The beltless effort sensor for small children is designed especially small and sensitive to higher frequency respiration movements and monitors respiration movements. The sensor does not require a battery or interface; it is easily activated by plugging the Safety DIN Connectors into any AC channel on the recorder.
