VoC Sensor Details #5

Closed erebuslabs closed 9 years ago

erebuslabs commented 9 years ago

Team is looking for details surrounding the VOCs to detect as well as sensor type:

  1. What exactly are we looking for (compounds, gases, etc. ) with the VOC sensor?
  2. Do you have a specific sensor in mind?
  3. What are you anticipating the use case for the VOC to be? (enclosure, in the ground, on the ground, etc)
erebuslabs commented 9 years ago
  1. Looking for gases.
  2. The cost effective solutions is any one of the 2600 Figaro parts such as the 2620
  3. Use case - the entire system would likely, ultimately, sit inside an enclosure with a forced air intake (beyond current project scope).

Great I will look into these, their associated circuits, outputs and sourcing, I will look into it but off the top: are they only available through figaro or are they simply the mfg?

eulerworks commented 9 years ago

...and which gases? Methane? O2? CO2?

erebuslabs commented 9 years ago

Let's go with Methane with a backup of CO2 (if that's not feasible). Also since the Figaro's might be hard to come across in short time spans - you can also consider Parralax sensors available from digikey.

How is the acquisition of sensors going? Need any additional help from my end?

eulerworks commented 9 years ago

We do not currently have a VOC picked out, we have designed the sensor boards around "any" analog type sensor so the VOC would just be dropped/soldered in, then the values handled in software. If you would like to have us implement one specifically could you order at least 2 and have them sent to PSU c/o Dr. Zurk?

Here is the tracking link Should be delivered to the university today (from there don't know how long it will take to get into Dr. Zurk's hands)

eulerworks commented 9 years ago

Great, thank you. Looks like they were delivered today.
