The Kitronik Air Quality Board provides a complete air monitoring and reporting solution for the BBC micro: bit. The wealth of on-board sensors and connection points allow you to collect extensive air quality data that can be stored in on-board memory and displayed on the OLED screen or transferred to a computer for analysis. Kitronik has also produced online MakeCode tutorials that are designed to introduce you to all of the key features of the board, see the 'Resources section below for links. The Air Quality Board is perfect for the classroom. Run short or long-term classroom experiments, such as

An all in one Air Quality monitoring and reporting solution for the BBC micro: bit
Measure temperature, pressure, humidity, air quality index, and eCO2
Pins 0, 1 and 2 are broken out to solder pads for additional I/O
The board features a black and white 128x64 OLED display screen and 3 status ZIP LEDs for visually displaying data
The real-time clock (RTC) and 1Mbit of on-board EEPROM memory enable timestamped data logging and long term data storage
Online MakeCode tutorials that introduce you to all of the boards key features
Run long term monitoring experiments in the classroom throughout the school year
There is an integrated edge connector for the micro: bit to slot into
Kitronik has produced custom MakeCode blocks for convenient and straightforward coding

Alternatively, it would make a great addition to an office/workshop, let science inform you when it's time to open those windows or remind you to ventilate your work area! The board also features a connection point for a solar cell that can be used alongside rechargeable batteries to keep your experiments running for longer. NOTE: Please ensure the correct rechargeable batteries are fitted before charging, they should be NiMh
