Sensing and Sensors

Remember/reprise art projects that use sensors, Pigeon Blog and Amphibious Architecturemovie (4 mins).

Current media includes sensing technologies that are often combined with video, graphics and data visualization to understand the environment in a more purely scientific context. Remembering Donna Haraway, “It matters what knowledges know knowledge …” – what are the implications of using media in this way?

“… how environmental processes and relationships are not only increasingly studied through computational technology, but also seen to be analogous to computational processes.  Read through devices such as sensors and satellites, and assembled into networks and code, ecology is now a shifting entity that typically becomes visible – and manageable – as information.” Jennifer Gabrys, Program Earth, p 15

      • air and soil temperatures, humidity, precipitation, and solar radiation (collected every second)
      • level and flow of every stream is monitored by pressure meters
      • three Raspberry Pi–powered acoustic sensors, detect bird/insect song
      • “phenocams” time-lapse cameras detect natural cycle (first buds, leaves etc)
      • thermal cams follow tree response to heat stress
      • 6 eddyflux towers detect movement of gas in air several times a second (carbon dioxide, water vapour, ozone and oxides of nitrogen.
      • experiments (heat specific area of forest and watch results)
    • purpose: to allow scientists to formulate strategies to mitigate the worst effects of climate change for forests, woods, lakes, grasslands, and farms around the globe
