Reidar.nordby@hiof.no 2. BACKGROUND AND THEORETICAL INFORMATION The project application is a solar panels field : monitor the luminosity and temperature changes in order to predict the field s power output, so power generation can be adapted elsewhere on

4 the grid to balance it. To do so, sensors are to be placed around the field, which data are sent using a wireless method called LoRaWAN. The data are then stocked on a database available on the internet. 3. PROJECT GOALS The group wants to be able to set up a smart network with the help of LORAWAN signaling technology. The goal is to send sensor Information from a node piloted by an Arduino Uno, to a LoRa Gateway connected to a Raspberry 3, and upload the data to a personal database on a server which will be running Linux or Ubuntu. We will make the encryption from node to database ourselves. We will also reverse engineer LoRaWAN technology to learn as much as we can about it. The application server is something we set up ourselves. The node will transmit data using a Semtech SX1272, and the gateway will be using an IMST IC880A as a receiver. 4. RESEARCH QUESTION How to benefit from LoRa radiolink communication for transferring environmental data. 5. PROJECT BOUNDARIES Install and set up the gateway using an IMST IC880A with a Raspberry PI 3 model B. Install Linux on a computer server, then install and set up a database in order to receive data from the gateway. Set up a node using a Semtech SX1272 mounted on an Arduino Uno Rev3, and send information to the gateway. Reverse engineer LoRaWAN to learn as much as possible and go in depth of it. If we are able, we will recreate the signal.

DESCRIPTION OF TASKS Pre-report Describing what the project is about and the parameters around it Sensors acquisition with Arduino This task will cover background information about the sensors used, how Arduino works, and program the code which will allow us to read the data and then process it. By utilizing a thermal sensor and light sensitive resistor at adequate locations, we will gather information that can be used for cloud and weather tracking. We are going to program the Arduino in C and C++ programming language. We are here focusing on how to make the sensor unit as low consumption and efficient as possible Arduino to node The node used is Semtech SX1272 Shield which is a low power, long range RF transceiver. It is using the LoRaWAN modulation technology to transmit information to a LoRa gateway. By learning how it works, we can program our Arduino to forward data to the node and send packets to our gateway First Encryption Security of the information is very critical. Therefore we need to build encryption that prohibits any other from obtaining our information. We are going through the history of cryptography to learn how it has evolved and how we can make our data secure. We will achieve secure data by programming the encryption in C and C++ into our Arduino. The data will be encrypted on the Arduino and decrypted when received at the database LoRaWAN communication Make node able to send information to our gateway using LoRa. Reverse engineer LoRa signal to learn how it works and hopefully be able to recreate the signal algorithm Raspberry PI 3 to Gateway Install Raspbian on the Raspberry PI 3. Install and set up the necessary libraries for IC880A to make it able to receive data from the node, and forward our packets to the internet using TCP/IP Database Receive packets from the gateway and store the values from the thermal sensors and brightness sensors in a database Database to website Establish a link between the database and a web server Website Create a website to present our data on an interactive site Last modifications Permit us to improve the system if we have some new ideas.

7 Expo preparations Prepare for Expo. Possibly make posters, photos, and items that could help us get people interested Expo Present our project to people and register feedbacks Report emake a report to register what we have done, and document all the steps so that the readers will be able to use this information for their purpose. 7.
