Arduino Xbee

The new Arduino Xbee shields (with the Zigbee modules from Maxstream) allow you to form one-to-one or peer-to-peer networks and are a snap to get working.

Without any configuration, you can use the Xbee as a simple wireless replacement for a USB cable, sending and receiving data with the standard Arduino serial commands. Just slip shields onto two Arduino board and you’ve got a wireless network. Or you can put the Xbee into command mode and group them into networks – for example, to have multiple boards sending sensor data through a central Arduino to the computer. The Xbee module can transmit up to 100 feet indoors or 300 feet outdoors (with an unbroken line-of-sight). Replace it with an Xbee pro for outdoor communication over as much as a mile. All the pins of the Xbee module are broken out to allow use of the advanced features of the board. The complete schematics and design files for the boards are available under a Creative Commons Attribution Share-Alike license from the Libelium Squidbee wiki download page. You can order fully-assembled Xbee shields from from PCB Europe (in Italy) or from Libelium (in Spain).

Pervasive healthcare conference

Pervasive healthcare is an emerging research discipline, focusing on the development and application of pervasive and ubiquitous computing technology for healthcare and wellness. Pervasive healthcare may be defined from two perspectives. First, it is the development and application of pervasive computing (or ubiquitous computing, ambient intelligence) technologies for healthcare, health and wellness management. Second, it seeks to make healthcare available to anyone, anytime, and anywhere by removing location, time and other restraints while increasing both the coverage and quality of healthcare.

A conference on Pervasive Healthcare is going to take place in Tampere, Finland, in 2008.

Some of the topics that will be discussed are:
– Wearable, ambient and home based health and wellness measurement and monitoring technologies
– Mobile and wireless technologies for healthcare information storage, transmission, processing, and feedback, including devices, systems and applications
– Sensor networks for pervasive healthcare
– Information management, processing and analysis in pervasive healthcare
– Networking support for pervasive healthcare (location tracking, routing, scalable architectures, dependability, and quality of access)
– Citizen portals and electronic citizen-managed health records

Tire Pressure Monitor for Lazy Car Nerds

To check your car’s air pressure, you could get an air pressure gauge, or kick the tires, but that wouldn’t be quite as geeky as this aftermarket tire pressure monitor. Four caps with sensor read each tire’s pressure and relay it wirelessly to the dashboard-mounted LCD.

WSN to monitor olive plants

Siemens and the Faculty of Electrical Engineering and Computing, University of Zagreb, Croatia, started a cooperation on the scientific research project of implementing WSNs in olive growing. The project is called MasliNET. The olive fruit fly (Bactrocera oleae) is currently being caught manually using “yellow board” baits and counted manually in the cycles of several-days. The MasliNET pilot project includes the use of wireless sensory nodes located on olive trees together with sticky baits, i.e. traps. The wireless sensor network would make the process automatic, reducing the human effort and field work, and providing for a geographical distribution and spreading of pest, as well as analysis of pest occurrence in the area.

Developer Kit for Self-Powered Wireless Sensors

EnOcean released a Developer’s Platform that enables OEMs to design self-powered wireless sensors that do not require batteries or external power. The EVA 120C Evaluation Kit includes everything necessary to quickly develop and test ultra low power wireless sensor modules for a variety of electrical and electronics applications.

Kit components include an EnOcean STM 110C solar powered sensor transmitter module and a development board with a PC interface. Detailed technical documentation, including data sheet, manual and user notes also are part of the kit.

The STM module is the only commercialized product that integrates a wireless sensor, low power radio, solar cell power generator, microcontroller and ultra low power sleep timer and threshold detector for energy management. All module elements have been optimized to work together.

Postdoctoral Fellowship in Volcano Monitoring Sensor Nets

WSU and Harvard, in Collaboration with the USGS Cascades Volcano Observatory and NASA JPL have an opening for for a new postdoctoral fellowship position in the area of wireless sensor networks for volcano monitoring.
The colaborations aims to develop platforms that involve real-time data collection of seismic, acoustic, and GPS data from a network of wireless sensors deployed on an active volcano. The project requires a tight integration of computer science and domain science expertise, including novel techniques for data collection, time synchronization, medium access control, multihop networking, and real-time data processing. There are plans to deploy a prototype network at Mount St. Helens, Washington, in the coming year.

This postdoctoral fellowship provides an opportunity to engage with an emerging research area involving wireless sensor networks and volcanology, to work with two university teams as well as researchers at CVO and JPL, gain real-world sensor network deployment experience, and build a strong publication record.

Applicants should hold (or will obtain within six months of application) a Ph.D in Computer Science, Electrical Engineering, or a related field.

Will Sensor Networks Suite Sril Lanka?

An interesting blog entry on WSN and their use in Developing Countries can be found here.

“When deciding on using wireless systems to Sri Lanka various matters have to be looked into before coming to the final conclusion of it. For example a typical sensor board used for these applications costs around two hundred dollars and the sensors it self has prices ranging form fifty dollars onwards. Even though companies say that this is an affordable solution as for a third world country like us this may not be a very cheap solution. If we were to develop a sensor based system for farmers in our country the costs we incur will be great and sometimes may not be feasible when compared to the available solutions. Furthermore in countries like ours the where labor cost is very low a farmer can afford about ten laborers at the cost of a single sensor. So converting form this manual labor system to a high technological solution like sensor networks in our country may not be easy.”

Wireless Bridge Monitoring

New York may be the first state with a 24/7 wireless bridge monitoring system, reports EE Times. The $500,000 project is being funded by the New York State Energy and Research Development Authority. Engineering professor Kerop Janoyan at Clarkson University is working with TransTech Systems (Schenectady, N.Y.) to craft a commercial version of their wireless bridge monitoring system.

The wireless sensor nodes use accelerometers and strain gauges as well as more exotic sensors from ultra sound to eddy currents, depending on specific monitoring problems. Wireless nodes, which are battery powered, are polled by a master single-board computer that aggregates sensor data and determines whether to alert inspectors.
