The breathing rate belt and pressure sensor pack combines a ±10kPa differential gas pressure sensor and a breathing rate belt to measure the expansion and contraction of a person’s chest while they breathe.
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 has 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.
