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.
