Hardwarová instrumentace pro kalibraci elektrochemických senzorů v laboratorních podmínkách

Abstract

This bachelor thesis focuses on the design and implementation of a device for laboratory calibration of electrochemical gas sensors. The primary emphasis is placed on the calibration of sensors for carbon monoxide (CO) and ammonia (NH₃) using precisely controlled gas mixing and measurement of the output voltage of individual electrodes. The work includes the design of a measuring setup based on the Raspberry Pi 5 platform, evaluation of collected data, and verification of sensor linearity in relation to the reference gas concentration. The final results present measurement data, linear regression, and an assessment of system accuracy.
