I have problem with UV/solar board...
Normally all working, but in an absolutely unidentified moment is on the ADC0 output (from solar) 5mV... This is a manual error status
I dont know why, test more capacitors on input, on power suply and etc, but not solved... After any time working normally...
Any idea? I have two PCB, both make this problem and just on channel for solar...
Tnx
Dear Josef,
Have you tried to move the operating amplifier directly to the sensor envelope? We work with extremely low voltage and anything can
be induced in the lead wires, even if we work almost short-circuit ...
Good luck!
