Humidity Transients signal correction model advice

Hi

I am working with some electronic chemical no2 sensor.

These sensor are effected by both temperture and humdity, Temperture is fairly simple to correct as its linear, but humdity introduce transients spikes, as shown in the extract from any application note. Has anyone worked on anything similar to correct a signal?

Thanks

Hello Dharmesh,

As per my understanding you would like to remove/correct the spikes from the humidity signal obtained from sensors.

For removing spikes, you can try using the “medfilt1” function in MATLAB which is 1 Dimensional median filtering of a signal.

It replaces values of a signal at a point with the median of the signal values in the neighbouring points. The number of neighbouring points to be considered can be given as an input.

Please refer to the following documentation to know about “medfilt1” and removing spikes from a signal:

I hope this resolves the issue you were facing.
