PmodIA Arduino Water Conductivity Kohm/cm

[Mesh]

Hi ,

I have PmodIA module which im trying to use it to measure water conductivity with arduino uno .

I tried to use the example code available IA_Wire but its seems not working for my application . i just need to read the Real Value nothing else .

The value im looking to measure is between 100 ohm to 100Kohm .  I tried to calibrate the module by using Zcal 100 ohm but had no luck the value is away from what im looking for .

Im not sure if im following the right calibration steps which its available on the datasheet. If you could help on easy way to do please post .

The code im using is attached for your review .

 

Thank you ,

Hi Meshal,

I know right now the PmodIA library doesn't fully support all of the features of the AD5933, so from my understanding our applications team is taking a look into getting the library better supported, especially in terms of adjusting the output gain factors.

Thanks,

Dear JColvin,

I am facing the same problem have to sorted out the problem with the library of PModIA as i am unable to use it with my arduino micro controller.

Hi @Zill,

Unfortunately our library is still not complete. Here is a forum thread were a forum member was able to get the PmodIA fulling working with code and tips on how to use(unverified). Hope this helps. 

cheers,
