The MonkMakes Air Quality Kit for micro:bit is based around the MonkMakes Air Quality Sensor. This add-on for the BBC micro:bit v1 and v2 measures the quality of the air in a room - how stale the air is. The outputs of the Air Quality Sensor board are analog: one for temperature and one for eCO2 (estimated carbon dioxide). These outputs can be read by a micro:bit and either displayed, for instance, as an air quality meter or logged over a period of time for all sorts of interesting experiments.

Note: this item is discontinued, so only available until current stock runs out.

As well as the Air Quality Sensor itself, the kit also includes a set of alligator clip leads to connect it to the micro:bit, and an amplified Speaker for micro:bit that can be connected to provide a warning of low air quality.

A full-colour 24-page booklet of instructions is also included.

Requires: BBC micro:bit v1 or v2.
