Matlab Minute: using an SGP-30 eCO2 sensor with an Arduino

Here we use the eCO2 sensor board from Seeed Studio. Here we show how it can be connected to MATLAB. We use it to read an approximate amount of CO2 coming out of my mouth. We assume that the baseline CO2 is 400ppm when the unit initializes. The SGP-30 is found in a number of air quality measurement devices, including ones that contractors like Mike Holmes uses.
It's a good idea to take into account sources of CO2 when setting up your sensor and best practice typically means trying to calibrate it to about 400- 500 ppm CO2 outdoors in an area that is not near industrial settings or sources of combustion.
The driver for this sensor was developed by Mr. Eric Prandovszky in York University's Lassonde School of Engineering. You can find it on the MATLAB File Exchange site here: www.mathworks....
