Quality dust sensor
Bought this one for my personal weather station, got it working with arduino in no time. Did not test it outside yet, but it looks promising. Arduino outputs enough power for running it, but you need level converter from 5v to 3.3v TTL to communicate with it. Operation is almost silent.
Do note that back side of the sensor has some flat components, so you'll need standoffs to mount it properly. Sensor comes with USB adapter for PC, didn't test it as I don't need it for the project.

Extremely versatile little unit
1 of 1 found this helpful Bought this to build a custom weather station
Pros:
+ Small footprint, can fit in a permanent shadow of my balcony railing, to get accurate measurements
+ Has deep sleep mode perfect to conserve battery
+ Has wi-fi to attach to home network and report the results
+ Powerful enough to serve the results via HTTP
+ Has enough on-board memory to provide nice UI and detailed week or month-long weather log
+ Has enough peripheral connections to allow for temperature, humidity, pressure and air pollution sensors
+ internally runs on 3.3v, compatible with most sensors without level adjustment logic
Cons:
- A bit of an overkill for just a weather station - I might add more sensors to it because I can.
