Robust Field Data Logger - Field Studies Hackday

  1. 1. Robust field data logger “flo(g)gr” Andy Piper @andypiper Neil Ford @neilcford Bristol Hackspace team the first Fieldwork Hackday FSC Slapton Ley, May 19-20, 2012

  3. 3. The Problem • new mobile devices are cool and clever… • but… • fragile • hard to extend • may not have connectivity Image credit: Marcus Grabac
  4. 4. Build something thatworks better here….
  5. 5. Design thoughts• robust!• physical - interesting but not distracting• not a continuous logger - record data where and when it is of interest; better for battery life and specific choice of stations• extensible / hackable - add new sensors later• SD card - easy access to raw data• not a replacement for traditional methods - enables quicker collection once those have been learned

  12. 12. Code!• Available on Github
  13. 13. Future• Field and user testing• Boxed (and funkier - dedicated PCB?)• Simple LCD confirmation display• Ports for probes etc• configurable via SD card to offer continuous log if desired• More data analysis tools - apps and web
  14. 14. Thanks• Neil - wiring ninja!• FSC Hackday team - aka “Team Awesome”• Bristol Hackspace - components and advice• anyone who put up with me complaining about Arduino and Strings… the first Fieldwork Hackday FSC Slapton Ley, May 19-20, 2012
