In the past half-century, the production of crops and livestock is strongly driven by the increased use of irrigation, agriculture machinery, fertilizer, and pesticide. A balanced amount of fertilizer is needed to increase food production and to meet food security requirements by allowing a stable amount of staple food production. However, the amount of fertilizer needs to be limited to prevent unnecessary greenhouse gas emissions such as N2O. However, the measurement of N2O gas in agricultural settings is challenging, generally frequiring complex systems. The development and evaluation of a new nitrous oxide (N2O) gas measurement system for agricultural fields is described. This system consists of an Infra- Red (IR) N2O gas sensors module placed within an acrylic chamber and located in a agricultural field. It is connected to an Internet of Things (IoT) module for recording gas level measurements in the cloud database, thus permitting monitoring of the measurements in realtime using a mobile phone. Firstly, measurements were taken using standard gas to evaluate the characteristic of the sensor module.ETC...
