Framing the problem

• where is the issue located? how can we get there and with whom do we collaborate?
  • https://www.flickr.com/photos/recordandremember/6151719485/in/set-72157627674148174
• what is the information that’s missing? How will it change the situation?
• what are they key parameters:
  • what intensities & exposure times are harmful to humans or the environment?
    • http://publiclaboratory.org/notes/warren/9-6-2011/hydrogen-sulfide-detection-fart-detector
  • where can it be detected? by smell range?
  • how long does it take?
  • how fast does it move/change, or how large an area does it affect?
  • what kind of detection? presence/absence? direction of flow? intensity or spot source?
• what equipment is available today, and who has access to it? How much does it cost and what is its sensitivity/latency? How much does it weigh and how does it work (air grab sample, continuous flow, soil sample?)
  • Google Shopping - as low as $109
• who are the potential users? What should the output data look like? Graphs, logs, lights, images?
• what are the data’s uses/outcomes? Legal? Avoidance? Remediation? Regulation?
• are there alternative means of detecting which are dramatically different/cheaper?
  • silver film tarnishes with exposure to H2S (see attached PDF)
