sds011lib is a fully-typed, nearly-complete, python 3.8+ library for interacting with the SDS011 Air Quality Sensor.
The SDS011 is a small, low-cost sensor created by www.inovafitness.com, used to measure particulate matter in the air. It can measure both PM 2.5 and PM10 values simultaneously, and connects to devices over a serial port, or via USB with an included adaptor.

pip install sds011lib
from sds011lib import SDS011QueryReader
from serial import Serial
# Setup a query-mode reader on /dev/ttyUSB0
sensor = SDS011QueryReader('/dev/ttyUSB0')
# Read some data!
aqi = sensor.query()
print(aqi.pm25)
print(aqi.pm10)
# Put the device to sleep
sensor.sleep()
# Wake it back up
sensor.wake()
