I'm trying to use a Soil moisture sensor with a Samr21-xpro and RIOT os.
The sensor used is as follows :
I have *4 soil jars (with different moisture concentrations)* that i'm
gonna use for testing, i've already tried to get moisture values with *Arduino
Uno* and they seem to be acceptable.
*For both, i used the built in ADC with 10 bits of resolution.*
But when i try to use the samr21, it gets me always 330 as value (10 bits
For the SAMR21* i used the default parameters for ADC_0*.
There is a way to rectify the readings, or some kind of calibration to do?
Thanks a lot,
*best regards, *
