Hi Werk
Thank you for your reply. Just to clarify, I have not chanced any weather sensors, only the transmitter circuit board and the software it runs.
I have done some checks on the system during the day today. By covering the solar sensor to simulate night, I measured exactly 0W/m2 in total darkness. Both times I did this (once in the morning and once in the afternoon) they gave the same, expected result of 0W/m2.
I can confirm I have a 10uF/16V Tantalum capacitor in C7 in the Transmitter board 3.12. This made me question what I had in my original Transmitter board, 3.11 and guess what I spotted that I had used: Electrolytic capacitors in C7 and C8. Maybe by using the correct type or capacitor, it has simply made the system more sensitive if these capacitors have an effect on this part of the circuit?
So, I have done nothing for today. I have left it alone without modification to see what happens tonight. But tonight I will try turning off the outside spotlight used so the webcam can see the weather station by night. I do doubt that this is what it is picking up however.
Thank you for your help once again. I will let you know how I get on; if the same problems occur tonight, I will try replacing the Arduno Nano micro controller.
