Description
The spirometer sensor is equipped with an OLED color display which shows sensor information and the measured values. This makes the sensor suitable to use as a standalone measuring instrument.
The spirometer can be used wirelessly via Bluetooth or wired via USB with the Coach 7 or Coach 7 lite programs/apps on computers (Windows and Mac), Chromebooks and mobile devices (Android and iOS).

All specifications of the sensor are described it its Product manual, see downloads.
Suggested biology experiments:
- Record breathing patterns before, during, and after exercise
- Investigate the effect of smoking on lung capacity
- Investigate whether there is a difference in lung capacity between students who participate in sports and non-athletes
- Measuring important lung capacities, such as:
- Forced Expiratory Volume (FEV) – the amount of air exhaled after a short period of sustained exercise. When this test is performed at one-second intervals, it is known as FEV1
- Forced Vital Capacity (FVC) – the total amount of air exhaled during a forced maximal exhalation after a full inhalation
- Tidal Volume (TI) – the amount of air inhaled and exhaled at rest
