CCS811 się quality sensor errors

Hello,

I bought CCS811 air quality sensor included on velleman weather station. After assembling the station I got the screen which said that all the sensors have been detected, but after a while I got an error as shown on the picture from attachment.

Is it the sensor error or is it broken or I had connected wires badly?

What should I do to get it work?

This clearly indicates a connection problem between the Arduino Mega Development board (VMA101), Sensor shield for Arduino® ATmega (VMA212) and the Air Quality sensor combo board (VMA342).

Please check your connections first:

Air Quality sensor board pin Sensor board
3.3V 3V3
GND GND
SDA SDA
SCL SCL
INT I19

Also check if the sensor board is connected correctly to the Arduino Mega Development board.
If that all fails, it might be a bad sensor.

Kind regards,

Hello Vel342

Unfortunarely I had tried all the options but they failed. Tomorrow my weather station is going away to Your service to Belgium.
