Plants are essential for thriving in rural areas, especially for agricultural purposes. Carbon dioxide is a greenhouse gas that warms the planet through its ability to hold onto radiation in the atmosphere, which can remain in the atmosphere for centuries. | Plants are essential for thriving in rural areas, especially for agricultural purposes.

+ | __SGP 30: CO< | ||
+ | |||
+ | How does it work? | ||
+ | 1) Uses metal-oxide technology to detect gases like ethanol, hydrogen, and other volatile organic compounds (VOCs) | ||
+ | 2) Sensor uses these readings to estimate what the CO< | ||
+ | |||
+ | Limitations: | ||
+ | |||
+ | __NDIR CO< | ||
+ | |||
+ | __Sensors to consider for use__: | ||
+ | 1) Adafruit MCP9808 QT: Temperature sensor. This sensor gives a high accurate temperature readings as stated on adafruit website the typical accuracy is +/-0.25 Celsius. This to addition to a carbon dioxide sensor could help develop the question and possible answers to how the concentration of carbon dioxide might affect temperature change at different levels of the lower atmosphere. | ||
+ | 2) HTU21DF: Humidity & Temperature sensor. This sensor takes measurements of humidity and temperature | ||
+ | 3) SHT31: Temperature & Humidity sensor. According to adafruit website, this sensor is more accurate with measurements with an accuracy range of +/-0.25 Celsius. | ||
+ | 4) SGP30: MOX Gas Sensor. This sensor would take measurements of eCO< | ||

+ | |||
+ | |||
+ | Goals: | ||
+ | |||
+ | __June 11th__: Determined to use CozIR®-A 5,000 ppm CO2 Sensor for ballon sensors for carbon dioxide [[https:// | ||
+ | |||
+ | __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: | ||
+ | |||
+ | __Troubleshoot ADPAA__: | ||
+ | - Install ADPAA from the wiki page [[https:// | ||
+ | - 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 ~/ | ||
+ | - 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 " | ||
+ | - Follow the other steps of [[https:// | ||
+ | - 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) | ||
