It logs to https://stats.vanhack.ca, along with the other laser stats.
It measures PM2.5 and PM10 (more info). I’ve done a bit of research into how to interpret these numbers, but there’s room for someone else to do further analysis. (hint hint)
In its current position, it tells us how much particulate matter is inside VHS near the laser cutter, causing discomfort and harm to the operator and other members. Causes for high measurements would include:
- filters being blocked/saturated
- laser door being opened too quickly
- air coming back inside from the alley
- particulate from the wood shop and other activities in VHS
