The MonkMakes CO₂ Dock for BBC micro:bit is a compact docking board that allows students to turn a micro:bit into a stand-alone carbon dioxide (CO₂) monitoring station. Designed to be used with compatible MonkMakes CO₂ sensors, the dock provides a stable base for displaying and logging air-quality data in real-world environments such as classrooms, offices, or shared spaces. By mounting the micro:bit securely, the CO₂ Dock makes projects more practical and presentable, supporting long-term monitoring of indoor air quality and ventilation effectiveness. It is ideal for STEM investigations, environmental science projects, and data-driven coding activities. Students can program the micro:bit using MakeCode or Python to display readings, trigger alerts, or record trends over time. This dock is particularly useful for projects focused on climate awareness, sustainability, and healthy indoor environments, helping students connect coding skills with real-world applications.
