De uitdaging, kun je met de MicroBit co2 meten en dat verwerken in een Excel? En nog niet zeker, kun je met je team een leuke prijs winnen ![image.png><](file-guid:0d54da4c-76f2-4d06-a01e-f81681136c85 "image.png" =300x400)\ The challenge, can you measure co2 with the MicroBit and process it in an Excel  Onderstaand is/was een internationaal project. De uitleg exact overgenomen is geplaatst door de leerling zelf op [https://en.vittascience.com/learn/tutorial.php?id=196/datastreamer](https://en.vittascience.com/learn/tutorial.php?id=196/datastreamer) Parts and tutorial here are in English, it was an international project Parts: * [Connector, breadboard en kabels](https://en.vittascience.com/shop/137/kit-de-prototypage-pour-micro:bit) * [SGP30 co2 meter](https://en.vittascience.com/shop/54/capteur-de-co2-et-cov-grove---sgp30)(new) * [SGP30 co2 meter used](https://nl.aliexpress.com/item/4001309985327.html?spm=a2g0s.9042311.0.0.40694c4dvxdwPb) * [Microbit](https://www.microbit.store/product/microbit-club-bundel-10-stuks/) **School project(PWS) by Tony Oelrich, Lieke Montauban van Swijndregt and teacher Eric Redegeld\ [Fonsvitae.nl](http://Fonsvitae.nl)** 2017-2019\ \ Put the Micro: bit with the led to the front into the [GPIO board](https://en.vittascience.com/shop/137/kit-de-prototypage-pour-micro:bit).\ The sensor can be connected in two ways:\ \- standard with the present SDA / SCL / GND / VCC port\ \- or with the pins P20 (SDA), P19 (SCL), 3,3V and GND from the GPIO board (in Red)   De codeer was be done on [VittaScience](https://en.vittascience.com/learn/tutorial.php?id=196/datastreamer) they can use the SGP30 and Makecode cant  Follow these instructions to setup the datastreamer:\ [https://support.microsoft.com/en-us/office/enable-the-data-streamer-add-in-70052b28-3b00-41e7-8ab6-8a9f142dffeb](https://support.microsoft.com/en-us/office/enable-the-data-streamer-add-in-70052b28-3b00-41e7-8ab6-8a9f142dffeb)\ You have a great tool to share data after this, click on the new add-in “Datastreamer” connect your Microbit with code to the computer\  And connect this After this you see the data For this project, I decided to create a 3D-printed box, this is not required but it adds a nice touch to the project:  What makes this project interesting. With the use of and second Microbit, you can use this remote collect remote the the data and receive this on the other MicroBit connected to an computer. And you can share the Excel data real-time!!\ \ So the base code and module is ready, can you expand this with Servo and other tools?
