The aim of this study was to develop a cheap, real-time, farm-scale GHG sensor system and to validate it against standard field GHG measurements (GC and static chambers). GHG measurements showed no differences in CO₂ levels recorded between glucose treatments and no difference was found between GC and senor CO₂ recordings. Conversely the sensor did show differences in CO₂ levels across glucose treatments and could detect CO₂ concentrations as low as 1g but strongly over estimated CO₂ concentrations. Results reflect issues in the chamber design but also highlight the importance of using these measurements as a method of validating that static chambers are working effectively. While time was insufficient to develop a sensor system, future studies should consider the costs and data storage space required to achieve such as system on a farm-scale.
