Hello guys… Im trying to setup with Dust Sensor with PMS7003 and Wemos D1 Mini…
But i got a so many error and i dont know this coding is right or not... I alreday made PMS7003 sensor + crystalLCD... its Work properly…
but i try to made with wemos d1… it`s to complicated…
Somebody help me…
here is my massy coding…
