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,
VEL342
Hello Vel342
Unfortunarely I had tried all the options but they failed. Tomorrow my weather station is going away to Your service to Belgium.
