Descripció del contingut i pla d'activitats:
In order to optimize crops and avoid plagues, Wireless Sensor Networks (WSN) are widely applied in many agricultural applications. The objective of these networks is monitoring the condition of crops. These networks can be part of Internet of Things (IoT). IoT means that each device is connected to the network, Internet, to send and to receive data. It is estimated that all IoT applications, not only in agriculture, by 2020 there could be around 5000 million objects. Many of these devices are nodes with few resources: little memory, low computing power, low energy and they are autonomous. They measure physical parameters, store and transmit to a control centre. The objective of this work is to develop a network for agricultural measurements at the ESAB (Escola Superior d'Agricultura de Barcelona) agriculture research centre: Agròpolis. The nodes measure several plantation parameters for monitoring the evolution of the crops, and transmit the data to a central computer to allow the monitoring of the evolution of plants. The important parameters to be monitored in any type of plantation are temperature, humidity and solar radiation, through discrete sensors or using weather stations that integrate different types of sensors. The choice of devices to use must guarantee the objective of minimizing costs and consumption, and be autonomous. The network will consist of low resources autonomous nodes that belong to IoT communicating using IPv6 (6LoWPAN).

Overview (resum en anglès):
Nowadays, new developments are being widely available in the Internet of Things (IoT) field. In order to handle a large number of devices and streamline processes in IoT, the use of Low Power Wide Area Technologies is also introduced in the Agricultural field. To further meet the project's needs and specifications, various IoT solutions will be explained; thus, Low Power Wide Area (LPWA) technologies, such as LoRa, Sigfox, and NB-IoT, will be analysed. As a result, the ¿Hybrid Network¿ was first introduced in a master's thesis, which utilised LoRa and Sigfox technologies. Further work is being done on this initiative, to examine the functionality and introduce new sensor types. Ultimately, the proposed system will be deployed and tested in a greenhouse owned by UPC, in Parc Agròpolis. The proposed solution is a combination of Sigfox and LoRa in order to take advantage of the benefits of both technologies simultaneously by mainly using LoRa technology as an extension of Sigfox. There will be devices acting as nodes, which will take the measurements from sensors. These devices use LoRa to send the data to a LoRa concentrator, which will, later on, send this data using a serial connection to a Sigfox gateway. The latter will be responsible for sending the payload to the Sigfox backend and ultimately to an IoT platform for storing and visualising the data.
