Gas sensing behavior of a single tin dioxide sensor under dynamic temperature modulation

The gas sensing behavior of a single SnO 2 gas sensor was investigated based on a dynamic measurement method in which temperature was modulated by heating waveform and frequency, and the results were compared with those of static measurement. The heating waveforms studied were rectangular, sinusoida...

More Information
Summary:The gas sensing behavior of a single SnO 2 gas sensor was investigated based on a dynamic measurement method in which temperature was modulated by heating waveform and frequency, and the results were compared with those of static measurement. The heating waveforms studied were rectangular, sinusoidal, triangular, saw-tooth, pulse, trapezoidal, and etc. However, the most essential factor was the modulated temperature itself, because any change in heating waveform and frequency resulted in the changes in surface temperature of the sensor element.
