V. CONCLUSION In this paper, we have presented a connected farm based on IoT systems for smart farming systems. To provide Internet connectivity for the sensors and controllers of the connected farm, we have deployed the &Cube, a standardized (i.e., complying with oneM2M specifications) device software platform for IoT devices. Also, we have used the Mobius, an IoT service platform (also oneM2M-compliant) that provides REST APIs with which the data collected from sensors (e.g., CO2 sensor) can be retrieved, but also the control commands can be sent to controllers (e.g., air conditioner). We have also implemented a smartphone application that allows end users to remotely monitor and control their connected farm, e.g., turn on air conditionerbypushingabuttononthesmartphone.Ourservice scenario with the connected farm shows a promise of building a farm knowledge expert system that encourages people to work in the agricultural industry.
