Performance comparison between seed respiratory CO2 detection system with two commonly used CO2 detection methods.
| | Detection limit | RSD | Typical measurement frequency | Reference |
| NDIR CO2 sensor | 30 ppm–50 ppm | 0.03 | 0.1 Hz | [33, 34] | Gas chromatography | 0.8 ppm–1.5 ppm | <1.5 | About 0.001 Hz | [35, 36] | Seed respiratory CO2 detection systema | 1.23 ppm | 0.00046 | About 0.2 Hz | |
