Hi tor, I’d like to build a rpi-based PM2.5 portable dust unit. Which, in your opinion, is the most reliable/affordable sensor for this task?

Not sure I understand – as PM2.5 is the sensor – and I am running mine from a Raspberry Pi, posting to a number of cloud based databases and display services such as ada fruit.io.
