Hello Arduino Fellas,
a) Apart from using a 1.5v dry battery with a (huge?) voltage divider, there is another way to simulate the microvolt/milivolt signal level for the INA input? (I want to test the device by comparing the input Vs the voltage output using a Oscilloscope and/or millivoltmeter).
b) Should I use a Low-Pass filter (cut-off freq around 40 Hz or less, to leave out the 50/60 Hz AC Hum) after the INA-amp or between the Pyranometer and the INA-amp?
Thanks in Advance.
