New book: Building Internet of Things with the Arduino

Authored by Charalampos Doukas

The Internet of Things (IoT) is a global network that links physical objects using Cloud computing, web applications, and network communications. It allows devices to communicate with each other, access information on the Internet, store and retrieve data, and interact with users, creating smart, pervasive and always-connected environments.
Despite the Internet of Things being a relatively new concept, there are already a few open platforms available that enable remote and seamless management and visualization of sensor data: Pachube, Nimbits, and ThingSpeak are just a few examples. And Arduino works with all of them.
The Arduino is an incredibly flexible micro-controller and development environment that can not only be used to control devices, but can also be used to read data from all kinds of sensors. Its simplicity and extensibility, in addition to its great success and adoption by users, has led to the development of a variety of hardware extensions and software libraries that enable wired and wireless communication with the Internet. Arduino is the ideal open hardware platform for experimenting with the world of the Internet of Things.

Wireless sensor network proven in action by EISLAB

A completely IPv6-based wireless sensor network has been put to a real life test in northern Sweden for over a year. In a private home in the town of Piteå, the heating system has been successfully monitored and controlled using a 6LoWPAN-based wireless network. A service architecture has been enabled by implementation of the Constrained Application Protocol (CoAP) and EXI compression.

“The challenge has been to use IPv6 in a real life project, to adapt the CoAP protocol with EXI compression to the sensor platform (the Mulle platform), and particularly to make the different parts of the system work together”, says Jonas Gustafsson, PhD and part of the research team at EISLAB led by professor Jerker Delsing. “But after some initial ‘struggle’ it has worked out fine; during runtime we have not encountered any major problems. This project is proof that there is possible to use an IP-based system to monitor and control technical systems such as a heating system, using very resource-limited sensor platforms like the Mulle.”

The wireless heat regulation project was carried out in a private home in Piteå, 30 miles south of Luleå where EISLAB has its home base and where the monitoring was carried out.

For more than a full year, the research team in Luleå has been able to monitor and control all functions related to the hydronic heating system in this house. The district-heating substation was controlled using a close loop control, and the wireless network was able to create a pleasant indoor climate by controlling valves and a circulation pump with adjustable r.p.m. Control computations have been made within the wireless network. In addition to the district-heating substation, also power sockets have been monitored through the wireless network. Control computations have been made within the wireless network.

Proof of concept clears the way for new projects
Jonas Gustafsson says the success with wireless monitoring and control of the house in Piteå constitutes proof of concept, and that this means it is time to move into new projects, even in an industrial environment.

“Now we have proof that monitoring and control of real life systems can be done with wireless sensor networks using technologies such as 6LowPAN, CoAP and EXI, and we are ready to move on to industrial projects. As an example we are talking to LKAB about monitoring of lubrication systems with the same type of sensor network and protocols”, says Jonas Gustafsson.

When moving on to industrial systems, one additional issue is that security aspects will have to be carefully addressed.

CIA Chief: We’ll Spy on You Through Your Dishwasher

More and more personal and household devices are connecting to the internet, from your television to your car navigation systems to your light switches. CIA Director David Petraeus cannot wait to spy on you through them.

Earlier this month, Petraeus mused about the emergence of an “Internet of Things” — that is, wired devices — at a summit for In-Q-Tel, the CIA’s venture capital firm. “‘Transformational’ is an overused word, but I do believe it properly applies to these technologies,” Petraeus enthused, “particularly to their effect on clandestine tradecraft.”

All those new online devices are a treasure trove of data if you’re a “person of interest” to the spy community. Once upon a time, spies had to place a bug in your chandelier to hear your conversation. With the rise of the “smart home,” you’d be sending tagged, geolocated data that a spy agency can intercept in real time when you use the lighting app on your phone to adjust your living room’s ambiance.

“Items of interest will be located, identified, monitored, and remotely controlled through technologies such as radio-frequency identification, sensor networks, tiny embedded servers, and energy harvesters — all connected to the next-generation internet using abundant, low-cost, and high-power computing,” Petraeus said, “the latter now going to cloud computing, in many areas greater and greater supercomputing, and, ultimately, heading to quantum computing.”

Petraeus allowed that these household spy devices “change our notions of secrecy” and prompt a rethink of “our notions of identity and secrecy.” All of which is true — if convenient for a CIA director.

Digi Launches Europe’s First Multi-Channel Wireless Module to Automatically Change Channels if Interference is Detected

Digi International released the XBee 868LP, Europe’s first multi-channel 868 MHz wireless module with Listen Before Talk (LBT) and Adaptive Frequency Agility (AFA) technology allowing it to automatically change channels if interference is detected. The low cost, low-power module is based on Analog Device’s ADF7023 transceiver and is ideal for energy management, sensor deployments and other wireless networking applications.

“When numerous 868 MHz devices are running simultaneously, increased risk of radio interference exists,” said Larry Kraft, senior vice president of global sales and marketing, Digi International. “With the XBee 868LP, you don’t have to wait for someone to change channels when interference is detected. The XBee 868LP automatically finds the best channel to improve network performance.”

“Digi is a leading developer of wireless modules, and we are excited to work with Digi in bringing this solution to market,” said John Greichen, product line director, RF Group, Analog Devices. “Our ADF7023 RF transceiver provides best-in-class interference blocking, sensitivity performance and low current consumption to ensure a strong connection and reliable data transfer.”

The XBee 868 LP features 30 channels for additional interference immunity. It operates in the 863 – 870 MHz range and offers low power consumption drawing less than 2uA in sleep mode. The module offers up to four kilometres line-of-sight range and is easy to configure with Digi’s free utility, X-CTU, which reduces development time from months to weeks. The module also supports over the air (OTA) firmware updates, minimizing deployment risks.

Sharing a common hardware footprint, the popular XBee product line offers developers tremendous flexibility and is extremely easy to use. Pin-compatible and interchangeable multi-channel XBee’s are available for global deployments, including a 2.4GHz version for the U.S. and Australia and an 865 MHz module for India. A 900 MHz version will be available in Q3 2012.

The XBee 868LP module is available now for less than $15 in 10,000 quantities. Development kits are available starting at $199 per kit. For more information, visit www.digi.com/xbee868lp.

Immediate availability of IBM Mote Runner beta 8 for Windows, Linux, and MacOS.

Mote Runner, IBM’s infrastructure platform for wireless sensor networks (WSN), consists of two parts: a run time for mote-class hardware such as MEMSIC Iris motes, and a development environment for WSN applications.

The Mote Runner on-mote run-time platform is based on a virtual machine tailored from scratch for resource-constraint hardware environments.

For this, it introduces a new byte-code language that, besides being compact and efficient, provides native support for reactive programming by means of delegates. Together with the run-time library built on top, Mote Runner provides a purely event-driven and thread-free programming model.

Blue ZThe development environment of Mote Runner consists a complete tool chain (i.e., converter, assembler, optimizer, shell) to develop mote applications in high-level object-oriented languages such as Java. It comes with its own IDE based on Eclipse as well as a mote and network simulation environment to ease application development and testing. A web-based deployment and monitoring framework in concert with an edge server finally allows the integration and visualization of Mote Runner sensor networks.
