Hi there community. I am building a weather station and I cannot get the data to log to the SD card. The content is written to the card except all the readings show 0 (zero), except for the voltage and time/date (please see attached screenshot). The current build is taking 84% of dynamic memory so I not sure if this may cause the problem. I removed the serial information as I don't need to display the information, I only need it to log the data to an SD card.
Im using the following components if it may help: Arduino Uno, Sparkfun weather shield, weather station, SD card shield v3, RTC DS1307, Sparkfun solar lipo charger.
I tested the serial data and everything seems fine except for the temperature that is giving a large negative amount of -999. Have checked everything over and over and think I am missing something basic.
Your help is truly appreciated.
