   - **sgp30_logger.py**: Logs carbon dioxide (eCO2) and Total Volatile Organic Compound (TVOC) from the SGP30 sensor into a CSV file automatically. (5-second collection interval)
   - **IMetXQ2_tri.py**: Logs data from IMetXQ2 and measures pressure, altitude, humidity, and temperature, and logs the measurements into a CSV file. For this code, you need to go in and change the USB_port to the correct port. (cd /dev and ls: plug and unplug, and you will see the name that changes. Run the script after cd /dev: ls and plug, then unplug and see which one was removed).
-  - Each sensor has a comment code to add a time stop feature, so the code will automatically stop at a certain hour it reaches. To add it: remove # from the line of code and change "from datetime import datetime" to "import datetime". Remove the lines that have datetime.dateitme(etc....) to a single datetime.(etc...).

+Analysis for future projects:
+  - Larger Parachute: The parachute in the garage is not big enough for a 10 ft height, 12.5 ft length, and 9ft width. The parachute did not deploy correctly on the Summer 2025 balloon launch. When we retrieved the balloon, the string broke off, and the bottom of the knot at the bottom of the package was intact, but the string going through the package looked as if it had been snapped.

+  * Talked about next steps.
+  * Meeting next week same time.
+==== Tasks ====
+  Liz - Draft of paper pitch.
+  Liz - Poster Draft
+  Liz - ERRC connect with them to see what we do.
+  Liz - Look into higher cost CO2 measurements.  How expensive, could we get some to calibrate with.
+  Liz - See if there is a gas dilution (using compressed CO2 tanks) to build a calibration system.
