THE INFLUENCE OF WATER VAPOR ON THE GAS-SENSING PHENOMENON OF TIN DIOXIDE–BASED GAS SENSORS

R. G. Pavelko

1. INTRODUCTION

Nowadays compact and cheap sensors fabricated on the basis of semiconducting metal oxides are increasingly used for domestic and industrial applications. After gas-leak detectors, the most promising market according to several manufacturers in Europe lies in the supply of air quality modules, which can not only monitor the contamination level of air, but also control and optimize ventilation systems. Such modules are already being integrated into cars, households, offices, and even in toilets all over the world. ...
