Hi, I am working with this sensor and I would like to test the library ... do you have any examples for use with Arduino UNO or Mega

Hi,
I am using this library along with SD Card interfaced to ESP32.
Individually both of them work fine. But as soon as they are connected together, both start to malfunction.

I have used different pins for SS.

Thanks..

Hi @marlon360

Thanks for this wonderful work. I would be grateful if could please clarify the units of various parameters which we can obtain by using "readHistogramData()" function. The parameters for which I want to know units are in the image below (the data obtained using your library):

The image below shows the units and values of the parameters obtained when SPI-USB converter and their software is used:

The values of corresponding variables are different by orders of magnitude, so I suspect that units are different when using their software and when using your library.

Waiting for your reply. Regards.

Hello,

Ive use your latest release of this library, temperature and humidity reading was OK, but PM 1.0, PM 2.5, and PM 10 reading seems to be incorrect, it stated 0 value for long time period ive tested it?

Any suggestion? Im using Wemos D1 Mini / esp8266

Dear Marlon

First of all I wanted to thank you for your fantastic work on this OPC N3.

I'm working on a school project with this sensor and I'm having some difficulties reading on UNO R3 WIFI.

I would like to know if any changes are needed in the library for UNO R3 wifi.
Best regards
