Measuring Solar Radiation based on Photovoltaic Cells

(22-01-2016, 14:11)laulau Wrote:  I'm using a LM358 instead of the AD822 for the moment.
Does someone have an explanation from what those spikes could

I never tested the circuit with an LM358, so I don't know if it makes any difference, but most likely the spikes you describe are due to some noise induced on the cable, between the solar / UV interface and the input of the ADC in the TX unit.
(Cable between de solar cell and the OP should always be very short, 20cm máx).

To eliminate the possibility of low spikes, the software on the RX rejects any reading below 4 Wm2, but if you are getting spikes above this threshold, better than raise this threshold is check the effect of the cable length in this behaviour.
