PASPORT Respiration Rate Sensor - PS-2133



Our Respiration Rate Sensor provides excellent data before and after exercise. Combining our Relative Pressure Sensor with a Respiration Belt, this sensor measures the change in pressure that occurs as the chest cavity expands and contracts during breathing. The Respiration Belt is wrapped around the chest and the rubber bladder inside the belt is inflated using the attached squeeze bulb.

Typical Applications

  • Conduct comparisons before and after exercise
  • Calculate possible correlations between respiration rate and heart rate
  • Determine the effects of altitude variation on respiration
