This library is written for the Alphasense OPC-N3 air qualilty monitoring sensor.
The Alphasense OPCN3 is an Optical Particle counter designed to measure and record air quality data. This implimetation is designed to read particulate mattaer data from the OPCN3 with an Arduino Due. The library can be easilly modified to be used with any Arduino supported device with an SPI interface.
