simple update for illuminance and co2

[scliddle]

This is my first contribution to this project and I was a little impatient.

These simple changes appeared to work for the CO2 sensor and the response to breathing near the sensor is visible.

The illuminance seems to be stuck at 1 and I think it may be a units problem. With this file in place and the raw values enabled, I was able to see a change, see output below. I think the lux was significantly higher than 3, as it was a flashlight directly in the top.
