Smart Agriculture with Advanced IoT Communication and Sensing Unit

In this practical project, an advanced reconfigurable communication unit is studied which is well-matched to be used in harsh agriculture environment. The unit transfers all data through SQL database and back-end with a UF (user friendly) web interface. It collects many data online from different sources like accelerometer, tensometers, CAN, temp. sensors and analog or digital inputs. The communication is based on Global System for Mobile Communications (GSM) and It uses GPS data to obtain accurate real-time localization for knowing where the machine is. The unit is powered with three different power sources. An external motor generator, a solar battery or a standard 12 V tractor battery. To enable the device working even without any of the above-mentioned power sources, an internal battery is also provided as a secondary source. The heart and novelty of the unit is a multifunctional Linux based Printed Circuit Boards (PCB) which would be described in detail. Several simultaneously working units, can be simply addressed using private standard network. The back-end lets the operators to organize chosen activities. One can select desired data to be detected. It is conceivable to arrange the time span between two different packages and the data acquisition rate which would be sent to back-end. Information are accessible via web interface and can be copied in CSV format for post processing. The whole system is also designed to capture user-defined data constraints and if such a constraint is touched, a warning message would be sent to a pre-defined contact.
