The version I have has an RS-232 output and a graphing program that runs on Windows. Connect it to an old laptop with an FTDI USB to RS-232 cable and you can log particle count histories. You have to clear the air intake port of dust once in a long while with a burst of compressed air.
The Sharp LED dust sensors aren't as accurate as a laser counter, but can give you a useful enough readout for dust and smoke:

These are probably what is in the cheapest air quality monitors.
