Wireless remote data
Technologies and sample systems that gather sensor data across distances, usually via radio links. This includes general telemetry and SCADA (supervisory control and data acquisition), especially for gathering data about wildlife, natural resources, and distributed energy systems.

The Crossbow MDA300CA Enviromental Data Acquisition Card: "is designed to interace directly with remote sensors like Soil Moisture, Humidity, Temperature, Wind Speed, Wind Direction, and Leaf Wetness. .. for Agricultural applications such as Irrigation Management, Early Frost Warning, Pesticide and Fertilizer Application.

Supports Remote Environmental Sensors including Soil Moisture, Humidity, Temperature, Wind Speed, Wind Direction and more.  Developed at UCLA’s Center for Networked Embedded Sensing."  UCLA Data collection software is available.  Crossbow sensor and software kits available online for under $2000.

BW: The Sensor Revolution: "Sensor networks promise a mammoth extension of the Internet. To date, the Web has been a showcase for the human brain. It specializes in the words, numbers, music, and images that mankind produces. With sensors, the network stretches to the far vaster field of global activity. This means such networks can cover every single thing that moves, grows, makes noise, or heats up. ..

York International (YRK ) Corp., which manages ventilation systems for more than 60,000 customers, plans over the next five years to install hundreds of thousands of networked sensors on its clients' air-conditioning units. These will monitor temperatures and automatically send updates to York's offices. That should lighten the workload for York's 2,000 technicians, boosting productivity by as much as 15%..  Tyco Thermal Controls LLC is turning to wireless sensors to cut down on the cost of laying wires in its pipe-heating systems. Such wiring accounts for two-thirds of the expense of installing monitoring systems. During the next three months, Tyco plans to launch customer tests."

MICA: The Commercialization of Microsensor Motes: Profile of architecture of Crossbow sensors and their networks.   "The first commercial generation of this platform was dubbed the Rene Mote,´and several thousand of these sensors have been deployed at commercial and research institutions worldwide to promote the development and application of wireless sensor networks.  The platform’s development community is based on the open-source model..  Most development work is done in the public domain, and it includes the hardware design and software source code. .. Although there’s no official consortium, the current community includes U.C. Berkeley, U.C. Los Angeles, Intel Research Labs, Robert Bosch Corp., U.S. Air Force Research Labs, Crossbow Technology, and others. ..

MICA developers and U.S. Air Force Research Labs used the new technology to create a wireless sensor network at the 29 Palms Marine base .. An unmanned aircraft dropped about 30 wireless magnetic sensors along a road. The sensors were packaged in a thin layer of foam to protect them from the hard landing on the desert floor. Once safely on the ground, the sensors formed a wireless network and began looking for magnetic anomalies. As a vehicle passed by the sensors, they would detect the vehicle from its magnetic signature. As the vehicle continued along the network, the engineers were able to estimate the vehicle’s speed and direction. The unmanned aircraft returned overhead to collect the data from the network and transmit them to the remote operation command headquarters. The entire development of the application, including the demonstration, took fewer than 60 days."
