Breathing Rate Belt Pack

Wireless Pressure Sensor & Breathing Rate Belt Pack

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.

How does it work?

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 used attached to the Differential Gas Pressure Sensor to monitor the change in pressure as the test subjects chest expands and contracts during breathing.

Breathing patterns

The Breathing belt is placed around the lower chest.

The bladder in the belt is connected to a Pressure sensor and lightly pressurised.

Changes in chest size due to breathing will create a change in pressure in the bladder, which in turn will be recorded by the sensor.


Our latest cross-platform software makes capturing your science experiments a breeze, designed for teacher's and students alike, the new EasySense2 software bring class collaboration to life.
