The Spirometer enables measuring the volume of our lungs. The sensor includes a tube through which it measures the air flow that passes through it. The volume (in liters) is calculated by the software area calculation function.
The tube has a narrow part in its center and it measures the flow rate by measuring the pressure difference between the two parts of the tube.
As with all Edu-Logger Sensors this must be used with the Edulogger USB module or the Wi-Fi module
