Documentation clarification #75
Description
For opc.OPCN2.pm() and opc.OPCN2.histogram() functions, PM1, PM2.5 and PM10 values are reported. I am assuming the units on these are μg/m3, however the documentation doesn't say. The documentation should be updated to clearly state the units that the data are being reported in.

Hi @dhhagan,
Thanks for developing this wonderful library. I need to clarify something from the documentation. It will be of a great help if you could help me with this.
I was reading documentation on "https://py-opc.readthedocs.io/en/latest/". The section "Connecting via GPIO" mentions "The OPC requires at least 250 mA, so powering directly through the RPi is not an option". Please explain me this as I do not have much knowledge of electronics.
Can't RPi provide this current? If not, please give me an idea of how to connect both RPi and OPC-N3 with the same power supply. Can both the device be powered using mobile charging adapter?
Thanks for your time! Waiting for your response...
