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

Hi @januarfa ,

I was also facing similar issue. This is most probably due to insufficient power provided to the OPC. I resolved my issue by providing power to OPC via 5V mobile charging adapter. Let me know if you are facing any other issue. All The Best.
