 +Metal oxide sensors generally show temperature dependence and cross-sensitivity to other trace gasses. Apparently, they are less sensitive in fluctuations of relative humidity.
 +
 +Sensor readings tend to drift over time, and can become at the order of the measured signal. Regular recalibration is essential.
