Hello
I am working on a weather station project, and my components are Arduino Mega + Ethernet Shield + RTC3231 + Weather Shield. To the Weather Shield, I have connected Weather Meters, and used code from this tutorial:
https://learn.sparkfun.com/tutorials/we ... nderground
I am loging total rainfall and maximum wind speed to SD card. This all works well. The problem is, that I get a random count for rain and wind speed, even if there is no rainfall or no rotation of anemometer.
What could be causing this random count of interrupt input? At this time I have the board connected via the USB wall addapter, could it be that there is to much power consumption and the voltage drops now and then?
I will try with 9VDC power supply, when it arrives.
Has anyone else got this problem?
