An Arduino driver library to communicate with the Cubic PM1006K particulate matter sensor. This sensor can be commonly found in inexpensive air quality monitors including the Ikea Vindriktning.
You can find the data sheet for this sensor here.
The PM100K uses infrared LEDs and an infrared detector to measure the particulate matter concentrations for 2.5um, 10um, and 1.0um particles in μg/m³. The sensor is designed to be used in conjunction with a fan to draw air through the sensor.
