An open source CO2/Air Quality sensor: STELLA-AQ #Space #CircuitPython #Feather #STEMMA @NASA
STELLA-AQ is a DIY handheld air quality instrument that combines carbon dioxide (CO2) and particulate matter (PM) monitoring capabilities in a user-friendly device. It requiring no soldering and offering a free build guide, open-source code, and a supportive community forum.
Built on the same platform as STELLA-Q, it allows users to interchange sensors and potentially create other instruments showcasing the STELLA platform’s modularity. It uses Adafruit Feather boards and interconnected sensors via solderless STEMMA QT I2C plugs. It’s programmed in CircuitPython.
STELLA-AQ was created by Paul Mirel and developed with Dr. Nyssa Rayne – Outreach and Communications Coordinator for the Terra mission.
