AS-MLV-P2 − Detailed Description

Cross Sensitivities

Due to the basic operation principle of MOS gas sensors, the

AS-MLV-P2 sensor component does have a cross sensitivity to

humidity changes. This effect provides additional information

and widens the application range for the sensor. This feature

especially supports applications in environments where the

detection of significant humidity changes is supporting the

functionality, such as bathroom and kitchen environments.

Figure 7 shows the dependency of humidity using the example

of CO signals to get a visualized feeling for the effect. Please

note that this dataset is just meant to be an example and the

values may vary from sensor to sensor.

to be a visualization of the influence of humidity and will vary slightly from sensor to sensor.
