The CO2 Bricklet 2.0 can be used to extend the features of Bricks with the capability to measure CO2 concentration in the air. The measured CO2 concentration can be read out in ppm. With configurable events it is possible to react on changing CO2 concentration without polling.
The Bricklet also measures temperature and humidity. These are used internally for compensation and can additionally be read out.
It is possible to apply an ambient air pressure value to achieve further compensation and better CO2 concentration measurement.
The CO2 Bricklet 2.0 has a 7 pole Bricklet connector and is connected to a Brick with a 7p-10p Bricklet cable.

* This is the temperature at the exact position of the sensor. If the Bricklet is used inside of an enclosure, the air around the Bricklet may heat up more than the ambient air. The Bricklet does have API to calibrate this kind of offset.
