PMS7003 PMS5003 Plantower PM2.5 dust sensor

How to use:

1. Install pyserial if you have not done so pip3 install pyserial
2. Edit examples.py, select port, a mode='passive' or mode='active' and named a logFile for saving data
3. Make sure designate the right USB port to the sensor, on Linux check it(them) by ls /dev/ttyUSB*
4. If running on mode='active', only interval of logging data is needed. For example, pms3.sampling(30) indcates a 30 seconds between data readding
5. If running on mode='passive', specifying duration of sleeping (fan is off) in pms1.sampling(60), 50 (seconds) for sleeping in this case, and the "warm up" time (fan on to purge the old air) such as pms1.warmUp(30) for 30 seconds of warm-up. 30 seconds are sufficient according to the Plantower datasheet.
