Accurate work with the wireless carbon dioxide gas sensor

carbon dioxide, CO2, photosynthesis, respiration

For experiments that are going to only have a very small change in the level of carbon dioxide, the following calibration procedure is recommended.

1. Turn on the sensor and collect data for 5 minutes.

2. Calibrate the sensor.

3. Continue collecting data for another 5 minutes.

4. Re-calibrate the sensor.

5. Collect data for another 5 minutes.

6. Re-calibrate the sensor.

You are now ready to conduct experiments with the carbon dioxide sensor that will have expected changes of 500 ppm of carbon dioxide over the course of the experiment.
