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 2021 there could be around more than 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.

 
Overview (resum en anglès):

Nowadays, the need to use smart devices with connectivity to information clouds is more common, both for control and for receiving information through sensors, for which there are a variety of technical solutions depending on the type of application of the use case, This could be some of the selection criteria, costs, coverage area, amount of data to be transmitted, etc.
The present work consists of a hybrid sensor network solution for agriculture, where they communicate with LoRa technology and this information is sent to an information cloud through Sigfox technology, in this way by only paying a subscription of a device. you can have many low power sensors working simultaneously.
A data protection system has been added to the LoRa communication of these sensors, to prevent any intruder from deciphering and interfering with the communication of the sensors, thus making a more robust and reliable system. In addition, a protocol for linking and light data transmission is proposed, which supports the reduction of energy consumption, which is self-sustaining thanks to the inclusion of an energy harvesting system by solar energy, thus making the system work for consecutive years of energy autonomy.
The coverage and operation tests have been carried out in urban and rural environments, guaranteeing correct operation at a maximum of 8 km in places without intermediate obstacles between the concentrator and the sensor, 1.5 km in rural environments with many obstacles and 500 m in urban environments. .
The data collected is stored in the cloud on the Google Cloud platform, from where it can be consulted anywhere in the world by the final user.
