GEMINI Weather Station Usage

The file RH_Temp_Logger.ino is used to operate the weather station and must be uploaded to the Arduino before use.
Install the Arduino IDE software and open RH_Temp_Logger.ino in the IDE.
In the built-in library manager, search for and install: SD, RTClib, DHT sensor library, MAX6675 library, and MAX6675 with hardware SPI.
Connect the Arduino's USB cable to the computer and select the correct board / port in the IDE.
Click "Upload" (Ctrl+U) to upload the sketch to the Arduino. The station is now ready for use with the GEMINI sensing app.
To verify everything is working properly, the serial monitor in the Arduino IDE can be used.

Expected Output

Connect the USB cable from the Arduino to a 5V power supply.
To update the weather station's RTC clock (GMT-0 time zone), turn on the GEMINI app prior to powering the weather station.
Depending on your use case, you may either place the weather station in the field to take measurements or attach the unit to the rover.
Data from the weather station is stored in the SD Card on the datalogger. The data is logged in a CSV format in a file titled YYYYMMDD.CSV based on the current date.
