  • Measuring breathing rates
  • Changes of the body in exercise

The Wireless Pressure Sensor & Breathing Rate Belt Pack combines a ±25kPa Differential Gas Pressure Sensor and a Breathing Rate belt to measure the expansion and contraction of a person’s chest while they breathe.

When used as part of a data logging experiment students can begin to explore breathing patterns.

​The Breathing Rate Belt is wrapped around a person’s chest region. Fitted inside the Belt is an inflatable air bladder, which is moulded to two rubber tubes. One of these tubes finishes with a hand pump bulb that is used to inflate the air bladder. The other tube is attached to the Gas Pressure Sensor which monitors the change in pressure during breathing.

Works with the following Dataloggers:

VHub4 and VHub8
