Looking for a robust co2 sensor

[kagadpencil]

I am looking for for a co2 sensor that I can bury 1 feet in a pile of sand. I want to sensor to be robust against the dust problem. Are you aware of any such sensor in the market ? I have done a lot of looking but have not found a sensor that has some sort of shield to guard it against dust. Looking forward to your suggestions.
