Project Objective:
This is a 24 hour LED clock that will display the amount of CO2 every hour. Using an air quality sensor, I plan to track the amount of CO2 in the unit of parts per million (ppm) in my local surroundings (home and school) and visualize that data in the form of a light clock. Similar to my prior “Energy” project, I will have the air quality sensor in the same enclosure with a solar panel, which will be placed near a window. The solar panel will provide energy to power the sensor.
In addition, I hope to relate this data collected to the broader picture of global warming. The specifics of how to do that are still not determined.
Rough Sketch: details still being worked out
Determining which sensor to use:
After talking with Jeff, I have decided to try out the Adafruit SGP30 Air Quality Sensor Breakout. We came to this conclusion based on both the price and the eCO2 ppm (parts per million) range.

Notes from speaking with Jeff:
- Interesting to compare the measurements of global CO2 (ppm/ppb) with the data I receive myself. Will the data from sensor track closely to the global aggregate?
- Make a comparison of data from API with data from my own sensor
- Read “Inhabitable Earth” by David Wallace Wells
- Listen to vox podcast with David Wallace Wells.
- Is there any way to create a sense of panic based on the data I provide
- Firey or smog-like visual
- How to connect the CO2 data with a broader concept of global warming
