Abstract
Resistive gas sensors are very popular and are commonly used to detect various gases and their mixtures. Theeir main disadvantage is very limited selectivity. Practical use of gas sensors in environenmental applications requires determination of concentration of a few mixed gases at the same time. We would like to present recent results of gas detection improvement by utilizing a single gas sensor and additional measurements to get more information about the sensor ambient atmosphere. The measurements utilize fluctuactions enhanced sensing and temperature modulation to gather more data and therefore assure better selectivity. Various algorithms will be considered to detect gas mixtures. The considered methods can be applied in cheap portable systems or in more advanced devices due to more complex computations. Finally, the new method of gas sensors parameters modulations by UV irradiation will be mentioned as well.
