Measurement of surface respiration: An IoT approach

This study investigates an approach to measuring surface gas fluxes based on the Internet of Things technology. A wireless self-powered, low-cost, lowpower, cloud-connected device is designed to record humidity and carbon dioxide concentrations at multiple points. The manuscript describes the concept and realisation of the device, the hardware chosen and the data communication chain. The manuscript also discusses a preliminary evaluation of the performances of the prototype in a controlled environment, together with major strengths and limitations.
