AgriNode Project

Orange Pi is a series of cheap single-board computers. It can run   It can run Android 4.4, Ubuntu, Debian, Rasberry Pi Image. In this post, I tried to install Eclipse Kura on a Orange Pi Zero which has    the AllWinner H2 SoC, and has 512MB DDR3 SDRAM. This board will be the next generation for our system (Agrinode project). The fist step, we install Kura on the board and test is to verify that it can work correctly as the Raspberry Pi.

AgriNode project: Building A Wireless Sensor Network for Agricultural Application AgriNode project goal is to build an Internet of Things – IoT solutions for various agricultural applications. We successfully developed the AgriNode system which is a Wireless Sensor Network – WSN consisting a gateway and sensor nodes. In the project, We utilized   Low-cost devices (Arduino, Raspberry) and Open-sources IoT platforms (Eclipse Kura, Reactive Blocks). Webpage: https://agrinode.github.io Report (PDF version): http://bit.ly/2lQc8Er Live data: https://agrinode.mybluemix.net/ui/#/0    ACKNOWLEDGEMENT I would like to acknowledge the support of Mr. Benjamin Cabé and Miss Roxanne Joncas from Eclipse Foundation . I also sincerely thank Mr. Tim Jagenberg and Miss Anne Nevin from Bitreactive for the help of building AgriNode project software.

The goal of AgriNode project is to build a Wireless Sensor Network - WSN for agricultural applications such as greenhouse management, monitoring water quality for a fish farm. The system can help farmers to monitor their own farm and support them in decision-making based on sensed data. The Fig. 1 shows the AgriNode system architecture. In this post, we demonstrate the hardware choices for the Agrinode system. To design AgriNode hardware system, we utilized low-cost electric devices that farmer can cover. Agrinode hardware system consists of two main parts: a gateway and sensor nodes.  The gateway (Fig. 2) is a Raspberry Pi 2 with Raspbian Os which is fully compatible with Eclipse Kura - the heat of AgriNode system. A Wifi dongle is added with Raspberry Pi for establishing a WiFi connection which sensor nodes can connect to.  Fig. 2 - AgriNode Gateway Each sensor node contains a microcontroller, power module and connected sensors. The microco...

Summary.  This tutorial demonstrates how to build a Kura application into a bundle by using Reactive Blocks . About Reactive Blocks. Bitreactive provides the visual development environment that allows java users build their own IoT applications by simply connecting building blocks. Each Reactive Block is designed for a specific purpose such as connecting to Cloud platform (IBM Watson IoT, Xively,...), providing MQTT protocol, LoRaWAN interface,... Reactive Blocks is a Plugin for Eclipse , which provides a development environment for a developer build a complex application by drag and drop reactive blocks from the Reactive Blocks libraries. For me, I have a very basic knowledge of Java but I can build a complex java application with Reactive Blocks. Each block has a description in the form of input and output pins and contract. In addition, Reactive Blocks provides the analyze and animation tools which are helpful for testing the applications. References: Block b...
