Calibration unit for spirometer
Burian, Tomáš ; Máca, Josef (referee) ; Vyroubal, Petr (advisor)
The task of the semester project was to become acquainted with methods of calibrating the spirometer and creating a calibration unit. Calibration unit must be able to calibrate both by volume and by speed. Because of that, the manual calibration of calibration cylinder is provided with a stepper motor mounted to the cylinder piston. The designed PCB will also be controlled by a program to control a stepper motor. The control system will contain 16 different options of selecting the speed of the piston
