ENGR: Upgrade/calibrate CO2 Sensors #12

Open KCollins opened 5 months ago

KCollins commented 5 months ago

The CO2 sensors at the air input and within the chamber are critical to measuring if and how much CO2 absorption has occurred per cycle. With our first build the product we used was very difficult to calibrate. To address this problem, we anticipate a sensor swap, but also need to design the chamber for more optimal air flow.
