Abstract
A method of compensating a MOS gas sensor is described and which includes using a MOS gas sensor to provide a signal indicative of gas concentration of a target gas in an ambient; providing a signal representative of dew point of the ambient; and modifying the signal from the MOS gas sensor using the signal representative of dew point to simultaneously compensate for the effects of both temperature and relative humidity on the MOS gas sensor.
