|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.

Wireless Sensors Monitor Volcanic Activities
: Roland Piquepaille
provides a summary of a new sensor net: "a wireless array of sensors has been deployed to monitor the eruptions of an active volcano in central Ecuador, the Tungurahua. An international team of computer scientists and seismologists installed a small wireless network of five nodes to record 54 hours of continuous infrasound data transmitted over a 9 km wireless link back to a base station at the volcano observatory. As the results are very encouraging, and because these wireless sensors are very cheap, this installation will soon be duplicated to detect eruptions of other active volcanoes. The team expects to deploy larger infrasonic arrays consisting of up to 50 nodes in the next six months either on Tungurahua or elsewhere in the world." 4:50:58 PM
