I don't have any personally, but the Plantower sensors are pretty straightforward. They just use standard UART serial, you can use an Arduino or even a simple USB-to-serial adapter, the only catch is that it must use 3.3V power and logic. Their datasheet describes how to wire them up and talk to them and you can also find plenty of code examples online. The PMS7003 is a very accurate laser based sensor with forced airflow, I trust it. Sharp also makes a much cheaper analog sensor based on IR, but I didn't get very reliable measurements from it. Edit: here you go https://learn.adafruit.com/pm25-air-quality-sensor/overview https://learn.adafruit.com/pm25-air-quality-sensor/overview . Is for the PMS5003 but that's basically the same sensor.
