I´m a newbee trying to upload data from a MHZ-19B (CO2) sensor and BMP280 (Temperature Higro and Pressure) to Thingspeak. I use ESP EASY in a Lolin Wemos D1 Pro mini
My problem is when I read data of my sensors in serial port everthing seems coherent no high value changes between readings, but in my Thingspeak Channel there are very unstable values, you can see here:
From what I can tell by looking at your channel, the values seem to be within normal variation expected from these sensors. Why do you feel you get different results on the serial port compared to what is posted to your ThingSpeak channel?
