Importance of Calibrating CO2 Sensor
The CO2 levels in my structure seemed to be a bit off (below expected values), so I decided to recalibrate soon after adding a new bottle. Well, I was correct, and for some reason my sensor calibration was off causing the reading to be lower than actual levels. While the manufacturer states the calibration should be good for three years growers may want to go through the recalibration process (takes under 10min. to do) a few weeks after everything is established to ensure accurate readings.
The sensor does need to be place in a natural CO2 environment (400ppm) during the calibration process. However, once calibrated (mine took only about 5min.) it was placed back in its original location it read a little over 1000ppm. So the previous setting of 800ppm was in actuality 200ppm lower than the actual. Knowing this I made some adjustments which I will go over in the following postings…
