The Zigduino is a pin and code compatible OSHW Arduino variant based around the ATmega128RFA1. This gives it a number of useful features above and beyond a stock Arduino:
Built-in 802.15.4 transceiver
Hardware AES-256 encryption module
128K of flash
16K of RAM
In order to improve the Zigduino’s durability for field sensor applicaions and provide full shield compatibility, all pins are protected by diodes and series resistors capable of absorbing spikes of ±30V. It can handle an input voltage range of 6V-30V with power supply spikes to -20V and +60V.
The Zigduino ships as a kit. Each kit includes:
- A bare Zigduino board
– Female headers for the standard Arduino pinout as well as the separate I2C and SPI connectors.
– One male 2×3 pin header for the programming port
– A 2.1mm DC barrel jack for power
– A card-edge RPSMA RF connector
– A 2dBi antenna.
The Zigduino is now on sale for $69.99! It is shipping worldwide and available for retail purchase at Metrix: Create Space. It will shortly be available from Seeedstudio and lipoly.de.

In 2007, there were 500 million devices connected to the Internet. By 2020, that could reach 50 billion, according to networking giant Cisco. This is the so-called “Internet of things”. A web where machines dominate. Strictly speaking, the Internet of things is a subset of a much bigger phenomenon: A machine-to-machine (M2M) net of sensors, actuators and processors.
M2M communications uses a device, such as a sensor or meter, to capture information – like temperatures, inventory levels or location status. This is then relayed through a network to an application, which translates the captured event into meaningful information. For example: a security breach, or when items need to be restocked or an accident has occurred.
CapGemini estimates that the world M2M market will be worth €27.4 billion ($39.3 billion) by 2013. According to Vodafone, just the wireless traffic alone will be worth €8.9 billion. Many of these nets of sensors and processors already exist in closed loops, such as in cars. Connecting these nets to the broader internet using conventional internet protocol inspires new business models.
Take, for example, San Francisco-based company, Streetline, which uses sensors in parking bays to allow citizens to find inexpensive parking, fast. This technology helps cities manage their parking resources more efficiently, while simultaneously helping to reduce carbon emissions.
Barcelona-based WorldSensing, uses a similar technology. The firm developed the technology to form a vast network of tens of thousands of geophones to allow cheap and continuous monitoring of carbon capture fields or conduct oil exploration.

The success of FlyPort WiFi module is due to the intuitive and easy programming essential software development environment thanks to the availability of APIs and functions already written and ready to be referenced in your code . The only bad thing is that you need to update the Framework to the 4th version.
From the OpenPicus site you can, among other things, download a sample project that includes the use of Flyport as a web server through which you can monitor the status of analog and digital inputs, plus you can interact with the board enabling or disabling the 5 digital outputs. Looking at the html code, what we see now is that it is a stylish remake of a web server made available by the Microchip as example of what it can be implemented by adopting their TCP/IP stack, so nothing new to this point of view.

If your home Wi-Fi router wasn’t cooped up indoors, it could send a signal about a 20th of a mile before the signal became too weak and distorted for a computer to receive it. Technology developed by San Diego startup On-Ramp Wireless uses the same frequency, but less power, to send data signals 45 miles, thanks to algorithms that make the signals very resistant to noise.
The technology, called Ultra-Link Processing, transfers data at a very low rate compared with a home broadband connection. But On-Ramp intends to offer it as a way to enable “smart energy” grids, in which simple sensors installed in home energy meters, for example, report local activity back to utilities, allowing them to manage power generation and distribution more intelligently.
Smart-grid infrastructure is needed to cope with the fluctuating output of renewable energy sources at large scale, and it could make feasible micro-generation, whereby consumers make their own power and sell any surplus back to the grid. Today’s smart-grid sensors typically use Wi-Fi-like technology with Wi-Fi-like ranges, or unlicensed radio bands that can reach a couple of miles. Cellular networks can also be used, but these connections are under growing pressure from data-hungry phones and tablets.

New software allows wireless sensor networks to run at much lower energy, according to researchers writing in the International Journal of Sensor Networks. The technology could improve efficiency for hurricane and other natural disaster warning systems.
Wireless sensor networks (WSNs) are used to monitor ecosystems, wild and urban environments. They have been vital in predicting events that threaten species and environments, including gathering information from animal habitats, in volcanic activity monitoring, flash-flood alerts and environmental monitoring. Wireless sensing in densely populated urban communities can be invaluable not only in monitoring the physical environment, but also for focusing on the impact people and their vehicles have on that environment through mobile emissions monitoring. Such sensing allows consideration to be given to such factors in planning for sustainable development. Unfortunately, the benefits of WSNs come at a price – they require energy.
Computer scientist Patricia Morreale of Kean University in Union, New Jersey and colleagues Feng Qi and Paul Croft of Kean’s School of Environmental and Life Sciences, explain how a mesh network of wireless sensors reports data to a central site for environmental monitoring and risk identification. They have developed such a system that reduces the energy requirements compared to conventional WSNs.

The ZigBee Alliance, a global ecosystem of organizations creating wireless solutions for use in energy management, residential, commercial and consumer applications, today announced it has opened two new offices in China to drive greater ZigBee adoption and address ZigBee standards to meet China’s specific needs for its rapidly expanding infrastructure and growing markets.
The Alliance appointed Jerry Huang as director of ZigBee Asia Pacific, Greater China representative, with offices in the Sensing China Center in Wuxi and in Zhongguancun Science Park (Z-Park) in Beijing. Huang, who has 20 years of marketing experience, will lead the Alliance’s collaboration on the Internet of Things industry efforts and standards development from these offices.
“ZigBee is very excited to have a local presence in China,” said Bob Heile, chairman of the Alliance. “China has declared the Internet of Things to be one of three strategic imperatives in its current five year plan and ZigBee’s comprehensive global standards for wireless sensor networks are key enablers for the IoT. Our two office locations will help us expand and deepen our collaboration with China in achieving this important objective.”
The Chinese Sensing China Center, located in Wuxi, is a thriving center of excellence on the Internet of Things. The Z-Park is one of the largest high-tech parks in China, located in the heart of the Chinese Capital City. Traditionally, many national and highly influential technology projects have initiated at Z-Park.
