The board packs a lot of sensors into a tiny form factor. You can measure temperature, pressure, humidity, eCO2, and calculate an air quality index. The board also features a black and white 128 × 64 OLED display and three status LEDs. You’ll also find a real-time clock module and 1Mb of onboard EPROM memory allowing for long-term storage of the data you collect.
To get up and running, all you need to do is add your own micro:bit and three AA batteries. And if you want to be a little more environmentally friendly, you can add three rechargeable batteries and a solar cell using the onboard connections. The Pimoroni website has links for learning how to use all the sensors and more. Head over to their site for more details!
