Today was spent comparing data once again to see if any trends emerged from the different locations. Right now it looks like our prototype is doing very well when compared to the GrayWolf, just not near as sensitive.
We are in the process of setting thresholds for each parameter based upon the readings from our prototype. These will be "comfort" readings for temperature and humidity, a scent threshold for VOC, a functional range for carbon dioxide, and then a hazard threshold for carbon monoxide.
The afternoon was spent working on the lesson plan and testing out the prototype. We took the opportunity to run our sensors while another group was making some cuts with a dremmel tool. The prototype registered a slight change in VOC content, from 124 ppm to 149 ppm. The largest change though was from the dust sensor which went from 0 mg/m^3 to 3 mg/m^3. Our intent is to perform more tests like this over the next week to see exactly what causes our sensors to register a change.
