Hi, recently I've been playing with a little CO2 sensor. It is capable of reading ppm (parts per million) of CO2 from near the sensor up to a max of 10,000 ppm. We have a small apparatus for holding various absorbent chemicals, such as lithium hydroxide, and are controlling the release of CO2 from a small tank with a valve. Readings are tabulated automatically from a small micro-controller every 2 seconds, and later this information if plotted in google sheets. Here is an example: Unfortunately, the sensor's capabilities are beyond our current experimental setup. With even the smallest burst from our supply tank (roughly 60 mL of gas as standard temperature/pressure), the sensor quickly plateaus to its maximum before eventually settling down.again. I was wondering if there was any mathematical technique able to interpolate/estimate the maximum value from the graphs we've been generating. The value does not need to be exact, even 20% accuracy would be fine for our purposes.
