Design of Spirometer using Arduino Nano

Spirometers are used to diagnose numerous respiratory conditions including habitual respiratory conditions that affect peoples in worldwide. Most of these people don’t have access to a spirometer because current models are more precious and the trained technician must bear to done the process. The purpose of this design is to develop a low- cost spirometer which would be suitable to use without the help of a trained technician. The design includes the physical design of the spirometer, software development to display and assay results. It also uses the Arduino nano as the micro-controller and pressure detector to measure the volume.
