Calibration of carbon dioxide sensors

To calibrate using outside air, take your sensor to an outside area away from running vehicles, people, animals, and other carbon dioxide sources. Let the sensor carbon dioxide value settle for about 20 minutes. (Since human breathing creates a significant amount of carbon dioxide, for best results leave the sensor during this time.) Then ...
