New Hardware - CO monitor

Would it be possible to switch out temperature/humidity for a CO sensor? Or just add one to the board?

I am looking into adding new sensors to LiV.

I think the best way to do this would be to have additional sensor nodes connecting to LiV over WiFi. The sensor nodes would have their own power supply/battery and would be easy to move around as long as they stay in WiFi range.

When it comes to CO sensors, my main concern is the accuracy and calibration of such sensors. CO is a lethal gas, so any measurement errors could have very severe consequences.

Analog sensors like this one: https://www.sparkfun.com/products/9403 require individual calibration in a controlled environment.  

Ideally, I would like to use factory calibrated sensors (just like the CO2 sensor) but so far I didn't find any supplier so I am trying to figure out ways to reliably calibrate analog sensors.

If I can find a CO sensor that connects over I2C, I could connect that directly to LiV and do some testing before I commit any resources to this project.
