I power it with 12V at the moment... I forgot why I removed the 9V regulator...![]()
Must put on a 9V regulator again...
I suspect of it, the temperature on the 3.3V regulator will lower a bit with the 9V regulator(24-06-2021, 20:28)edr1924 Wrote: The board was used to send rain and wind data but this week I separated the two.
I had many problems with strange wind and rain values when it was windy and raining at the same time. So this week I made a arduino Uno shield with another transmitter for Rain data.
Also I had trouble with the chinese Arduino Nano on this board. Maybe it couldn't handle the 2 interrupts simultaneously, hence the strange values?? This week I couldn't upload any more so as you can see I used a normal Arduino Uno with a genuine Atmega chip.
Whatever the issue, don't think the problem is handle the 2 interrupts simultaneously. Long time ago I experienced a similar issue, but just with the wind, found out that it was caused by a very long cable between the anemometer and the TX unit.
