Paper Abstract

In the present work, automation of a dynamic system to measure response of gas sensors based on quartz crystal microbalance (QCM) is presented. Automation was used to study transient response, which is necessary for sensor characterization. A valves system, which controls the gas flow towards the sensor, was implemented to generate the step function. The system was fully automated by using a PIC16F877 microcontroller. Results of sensor response measurements are presented.
