Hello,
I am trying to use a CMP11 Pyranometer (see https://www.kippzonen.com/Product/13/CMP11-Pyranometer) with Lan Controller 3.8. The sensor supplies a low voltage of 0 to 20 mV in relation to the amount of incoming sun radiation. I have connected the two wire sensor to analog input 1 and I have set up the input at 5v but the value was not as expected (something like 25 (left) with 0.02 (right)). I wonder if I can read precisely such small voltages, under 20mV, with the Lan Controller's analog inputs.
Thank you.
