ESP8266 Air Quality Sensor CCS811
Posted: Wed Mar 17, 2021 8:18 amI am doing a project where I have to connect an ESP8266 NodeMcu v1 board (attached photo) and a CCS811 air quality sensor. Attached photo of the connection. Connection
In arduino I have version 2.7.4 of esp8266 installed. I have installed the "Adafruit_CCS811.h" library and I am trying to run the example called "CCS811_test":
The problem is that when I open the Serial Monitor, I get
I think the connection is well made, so I don't know what that error might be due to.

Serial.print(ccs.geteCO2());
Serial.print("ppm, TVOC: ");
