|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.

New HazMat Detection for Super Bowl XL
: ""In past years, security personnel have walked around Super Bowls and reported in regularly by radio," said Jeffrey Ricker, CEO of Distributed Instruments
, the Sterling Heights-based company that has developed and supplied the software and servers that enable this sensor fusion system to integrate all data in real time. "This year the very small computers they carry will instantly communicate any suspected materials to all members of their network instantly." " 11:00:51 PM

Industrial Telemetry demos wireless compost network: "The BioMESH System includes radio-equipped temperature probes that enable operators of large composting facilities to monitor and regulate the internal temperature of compost. .. ITI has field trials of the BioMESH System underway at multiple compost facilities across the country. ..
The temperature probes integrate temperature sensors with radio modules in sealed, weather proof, caustic proof housings. The radio modules utilize a patented wireless mesh communications protocol to support connectivity to the temperature sensors. The probes operate on battery power and feature a scheduled "sleep" mode to provide extended battery life. The BioMESH housing is made from heavy-duty PVC and stainless steel components." 12:47:30 PM
Sensors watch Barrier Reef coral: Cairns, Australia: "The Australian Institute of Marine Science (Aims) is working with James Cook University on a project called Digital Skins. Smart sensors, developed originally for use in nuclear power stations, are placed in the ocean and also in water catchments on the mainland. They are able to communicate with each other to monitor events such as coral bleaching as they happen. ..
Each sensor in the skin has its own numerical address and operating system. Using a global position system, the sensors know exactly where they are. Parameters such as salinity, temperature and nutrient levels are measured.
Communicating with the sensors is a challenge, particularly for those sensors located out on the reef. Using a technique that was discovered by the British during World War II, microwave signals are sent along the surface of the ocean. Initial tests have seen data sent as far as 70km (43.5 miles) in one hop.
The final link in the chain is grid computing. All these sensors create terabytes of data every day. High-speed links allow the various institutions to share their computing power. " 12:42:57 PM
