SDI12 array dimensioned to 3 sets of data from the same Device


Shanks.J Apr 23, 2020 08:54 PM

I am measuring 3 variable within a soil probe.
the probe has 8 sensors, which means there are 3 sets of 8 values to pull.
soil moisture , soil salinity and soil temperature.

I am trying to make the array dimensioned to 24 & define the start variable position in the array
by defining the start variable position in the array ie moisture 1-8 , salinity 9 - 16, temperature 16 - 24.  

So far i am not having luck. and getting NANs accross al varible, is this because of the set up of th alias?
please see below.

Use a positive number in the FillNan parameter of SDI12Recorder(). See my response to your other post.

Thanks JDavis,
where is the fill nan?
