What I want to do
Dr. Crispin PIerce (UW-Eau Claire) and I, Jonathan Dahlen (UW-Stout), are researching into particulate matter 2.5 and 10 around frac sand mines. What we are looking to do is create a device that can sample both PM 2.5 and 10, but also collect measurements of temperature and humidity.
My attempt and results
We are currently using direct reading instruments (Dusttrak 1 and 2, Dylos), but humidity is playing a factor in our results and we would like to eliminate that problem so we are able to just collect particles.
Questions and next steps
We are wondering what some of the people from Public Lab have for thoughts or ideas on our project.
Why I'm interested
We would like to add to the array of inexpensive tools in monitoring around frac sand facilities.

Cool!
Does the dusttrack or dylos have a sensor-out port? I'm thinking we could hook it up to another data logger and collect humidity data on the same time stamp. I have an SHT 15 temp and humidity sensor here and an arduino-based datalogger here that writes to an SD card-- if we could get it to read the Dusttrack then you'd be set.
can you find any info on the Dusttrack's communications protocol or output?

Also, I noticed your two Dusttrack monitors you're using had different air intakes (pic below). is the cyclone really important? would it improve the data from the dylos to have a cyclone?
