Metal oxide Sensors

Operating principle of metal oxide gas sensors by Figaro.

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.
