The Kruskal-Wallis rank sum test showed that the sensor was sensitive to varying amounts of NaHCO₃ both in the field (p=2.2e^-16, df=2)  and in the lab (p=2.2e⁹, df=2). Results from the Dunn Test showed that the sensor was sensitive to all concentrations of NaHCO₃, both in the field and in the lab. Lab recordings of CO₂ showed greater peaks (maximum= 16,158ppm) than in field recordings (maximum= 3304). In the field, the addition of 1g of NaHCO₃ showed a continuously rising production of CO₂ in the chamber while 3g and 5g both saturate approximately at 150 seconds and less CO₂ is detected from the sensor over time. In the lab, 1g of NaHCO₃ saturates in producing CO₂ at approximately 125 seconds while 3g and 5g produce peak CO₂ levels much sooner (<100 seconds) but then immediately drop to as little as 0ppm then rise slightly before stabilizing.
