+Intro & Background Presentation (June 10th, 2025):
+Michael's Presentation IREC REU 2025: [[http://www.openscienceassociates.com/delene/REU2025_OverviewPresentation.pdf]]
+Goals:
+__June 11th__: Determined to use CozIR®-A 5,000 ppm CO2 Sensor for ballon sensors for carbon dioxide [[https://www.co2meter.com/collections/1-percent-co2-sensor/products/cozir-ambient-5000-ppm-co2-sensor?variant=839970488340]]
+__June 12th-13th__:
+  - Work on Wiring construction
+  - Understand ADPAA & Installation
+  - Decide which logging program to use for the weather balloon
+__June 16th-17th__:
+  - Finish the previous week work if not finished
+  - Test sensors with new cord
+  - Spot tracker determination
+  - Once Co2 sensor arrives, test and code
+Accomplished: Install ADPAA (aplot), discussed spot tracker with SOG (They will have a spot tracker, so might not need two), understand aplot (help handle raw data), created own 3d-paw wire compatible with H, T, and P sensors (Humidity, Temperature, and Pressure sensors).
+__Troubleshoot ADPAA__:
+  - Install ADPAA from the wiki page [[https://aerosol.atmos.und.edu/ADPAA/index.html]]
+  - Be sure everything is up to date (In terminal: sudo apt update), if not, then upgrade needed software(IN terminal: sudo apt upgrade)
+  - Ensure you have a Python environment and other needed tools installed in the terminal: sudo apt install python3 python3-pip csh tcsh gfortran git
+  - Encountered the problem of trying to find ADPAA (It was in downloads: cd ~/Downloads), CoPAS
+  - In terminal: ls *.tar.gz (To find the download of ADPAA since it will be an .tar.gz file
+  - When trying to install and open wget was not installed, if it is not in terminal: pip3 install wget
+  - Install ADPAA in terminal: ./CoPAS.py ADPAA
+  - If you encounter "git" not defined error download the package in terminal: pip3 install gitpython
+  - Follow the other steps of [[https://aerosol.atmos.und.edu/DataProcessingGuide.pdf]]
+  - To test type aplot in terminal (Aplot is an open source software for processing and analyzing raw data.
+__Guideline to wiring for 3D-PAWS__:
+  * Color does not matter but once you assign each wire, they matter
+  * The most important pins: Power (typically 3.3V), Ground (GND), Clock (GP103: SCL1), and Data (GP102: SDA 1)
+  * In reference to the raspberry pi usbs being on the left side the pins start in a number order left being the first: Power 3.3V (1st pin) if 5v power (2nd pin), Ground (6th pin), Clock (5th pin), and Data (3rd pin)
+  * Each sensor will have the code name above to see which wire plugs in where on the sensor
+  * For the BMP280: SCK is Clock pin, SDI is the Data pin
+  * To test if the raspberry pi is detecting any sensors in terminal: sudo i2cdetect -y 1 (It will be a diagram with dashes and numbers should show for each sensor: if you have 3 sensors three different values should be present)
