FAQ & Data
Troubleshooting extraction issues & understanding your CSV.
1. Troubleshooting Extraction
My GPS is returning 0.000 for Lat/Lon?
GPS antennas cannot penetrate concrete ceilings. You must have a clear, outside line of sight to connect to satellites. Go outside and wait 1-3 minutes for a solid satellite lock before gathering data.
My CSV columns are showing 'NaN'?
'NaN' stands for Not-a-Number. This occurs when the board attempts to read a sensor on a specific port (e.g., A0), but the sensor is plugged into the wrong physical port (e.g., D2) or disconnected entirely. Double-check your setup against the Board Layout.
My exported CSV file is completely empty?
The Seeeduino writes data to an embedded volatile storage when deployed. If you disconnect the battery before extracting the data via USB, all volatile data is instantly erased. Maintain power until extraction is complete.

Values Reference
Analog Sensors (Light, Sound, Rotary): Output is a percentage (0.0 to 100.0), where 0 is minimum (dark/quiet) and 100 is maximum.
Temperature: Output is in degrees Celsius.
Ultrasonic Distance: Output is in centimeters (cm).
GPS: Latitude and Longitude are in decimal degrees. Time_UTC is in Coordinated Universal Time.
