Adafruit offers three CO2 sensors (SCD30, SCD40 and SCD41) that measure CO2, temperature, and humidity.
This is a simple Pioreactor plugin that returns CO2 readings (or all readings) at a set duration from stemma QT connected Adafruit SCD sensors.
Install with pio install-plugin co2-reading-plugin
from the command line, or in the Pioreactor UI.
Important: after installation, this requires a reboot of your leader Pioreactor
This also adds a chart to your overview page that displays the CO2 readings per Pioreactor.
