AIR: Area's Immediate Reading

AIR is a public, social experiment in which people are invited to use Preemptive Media’s portable air monitoring devices to explore their neighborhoods and urban environments for pollution and fossil fuel burning hotspots.

Participants or “carriers” are able to see pollutant levels in their current locations, as well as simultaneously view measurements from the other AIR devices in the network. An on-board GPS unit and digital compass, combined with a database of known pollution sources such as power plants and heavy industries, allow carriers to see their distance from polluters as well. The AIR devices regularly transmit data to a central database allowing for real time data visualization on this website. The AIR devices are based on the Arduino platform.

XBee Wall Router Makes it Easy to Deploy and Extend ZigBee Networks

Digi International today introduced the XBee wall router, a ZigBee router used to expand a ZigBee network’s range. By plugging into standard power sockets, XBee wall routers are easy-to-install building blocks for self-healing ZigBee networks and ideal for creating robust Drop-in Networks.

“The XBee wall router’s small form factor and ease of deployment make it perfect for creating Drop-in Networks,” said Larry Kraft, senior vice president of sales and marketing, Digi International. “Installation is easy and completely unobtrusive.”

Choosing the best system software architecture for your wireless smart sensor design: Part 2

From, the second part of the article by Anton Hristozov:

Any operating system strives to provide a framework for convenient and easy application software development. Through the use of multitasking and hardware abstractions, an operating system is useful to a programmer because it isolates dependencies from the particular hardware details through the agency of a Hardware Abstraction Layer (HAL).

One of the uses of a real-time OS (RTOS) is to guarantee determinism for real-time performance. It is equipped with facilities which can help the user to meet their application’s real-time goals. For the OS to be real time it needs to have a special architecture, especially in the scheduler, a main component of the RTOS.

The 2nd European Summer School on Knowledge Discovery for Ubiquitous Computing

Porto, Portugal 2-9 March 2008

The goal of the summer school of KDubiq is to establish a common ground for the integration of the involved fields and to support the formation of a new community. Starting with an introduction into embedded systems, more specialized courses focus on wireless sensor networks and data streams. Based on a course on algorithmic foundations of distributed data mining, privacy issues, Web 2.0 and grid aspects of data mining are being taught. All courses come along with exercises for hands-on experience.

The School’s website is here.

Nokia’s Eco Sensor concept gets right with the greens

The Nokia Eco Sensor concept device consists of two parts: a wearable mobile phone (duh, it’s Nokia) with giant display and a remote sensing unit which keeps tabs on your health and external environment. Nokia research envisions that the sensor unit would be worn on a wrist or neck strap made of solar cells. It would thereupon communicate back to your phone via near field communications (NFC) or RFID. What you monitor (i.e., the sensors you get) will be customizable based on user preference. You know, like the burn from your jetpack and rate of your daily food replication. Thanks for the look into the future Nokia!

MSPsim – a Java-based simulator of MSP430 sensor network platforms

MSPsim is a Java-based instruction level emulator of the MSP430 series microprocessor and emulation of some sensor networking platforms. Supports loading of IHEX and ELF firmware files, and has some tools for monitoring stack, setting breakpoints, and profiling.

Software development for wireless sensor networks is a challenging and time consuming task. The resource limited hardware with limited I/O and debugging abilities combined with the often cumbersome hardware debugging tools makes low-level debugging on the target hardware difficult. MSPsim, an extensible sensor board platform and MSP430 instruction level simulator that simulates sensor boards with peripherals for the purpose of reducing development and debugging time. The use of a simulator also enables testing without access to the target hardware and makes more advanced debugging and instrumenting possible.
