Can You Recommend a CO2 sensor for the Raspberry Pi3?

I'm assisting a school in a project where the kids want to measure CO2 around their school. They'll use the Pi3. Can anyone recommend a C02 sensor for use with the Pi3?

Thanks.

Just as an alternative, I've used this Sparkfun breakout which is essentially the same as the Adafruit part that Gene mentioned https://www.sparkfun.com/products/14193.
Very simple to use. Communicates via I2C and can be temperature compensated using an optional thermistor.

The OP should beware that these (Adafruit and Sparkfun parts) are not really CO2 sensors, being affected by many other things as well.
