The SmartSensor is a handheld electronic device and works with an app on a smartphone. The farmer uses the handheld device on-the-spot at the field. After the SmartSensor is connected and communicating with the app,
the farmer is instructed how to do the sampling. On several spots –representing the field size – the farmer is scanning the soil and the data is captured by the smartphone. When all samples are taken the data is send to a central computer, processed and the results of the analyses are presented after a while in the app. An advice module provides the farmer what is most appropriate to do. The advice can be, either to add nutrients, raise the soil organic matter or increase pH of the soil.
