How to use Alphasense OPC N2 particle sensor and NDIR CO2 sensor with Arduino/Rpi?

[dashan]

Does anyone have any experience with Alphasense OPC N2 particle sensor and NDIR CO2 sensor with Arduino or Rpi?

I tried to get data out using both Arduino and Rpi separately, but maybe i the wiring was wrong or the coding was wrong, so none of them works now.

I would really appreciate any help on this subject please!

For OPC N2 i found a library called py-opc but i dont know how to use it. Whenever i run the example code it came with "alpha" is not defined error comes out https://github.com/dhhagan/py-opc

For CO2 it only work with the software it came with but i am trying to make a small unit so even a laptop is too big that is why i am using Arduino/Rpi. Like i said i cant get data out using Arduino. I dont know how to attach a pdf in the post otherwise i will upload the instruction of the sensor.
