Davide Gironi: MQ gas sensor correlation function against ...

Jul 02, 2017· We get the a and b coefficients for the correlation function ppm=a* (Rs/Ro)^b from the sensitivity characteristics curve. To estimate the Ro, we read the sensor resistance at temperature T1 and humidity H1 ( Rs_T1CH1%) given a know amount of gas to estimate. We are trying to estimate Ro at 100ppm of NH3, at temperature 20C and humidity 65% ( Ro ...

Measurement of NH3 Concentrations in Stack Flue Gas Using ...

The ammonia (NH3) gas is injected to remove the NOx and thus reduce the NOx concentration in the stack flue gas. With conventional NH3 analyzers that perform measurements indirectly, NH3 concentrations are obtained through a sampling system. Therefore, there are problems with the maintenance and running costs of the sampling system, and time delays in measurement.
