Sensor Systems for Smart Agriculture

This paper presents two sensor systems used in smart agriculture. The first sensor system is capable of remote monitoring at real time the condition of grains stored in silo bags. The second sensor system comprises soil's nitrogen (N), potassium (K), phosphorus (P) and pH sensors to optimize at real-time the precise application of fertilizers. The details about the design and fabrication of these sensor systems together with some experimental results obtained during field tests are reported.
