Optimization of the gas sensor parameters, for example
grain size, band gap, crystal quality and thickness greatly
influences the response and recovery of the sensors. It was
shown that deposition parameter control, post deposition
treatments, and impurity doping affect physical parameters
of the metal oxides. In the case of SnO2, an increase in
pyrolysis temperature during deposition reduces the influence
of water vapor on the conductivity of the sensors and,
therefore, the influence on the sensor response [7,8].
