I have recently bought your Grove multichannel gas sensor v2. but when i try to put my coding and add library of seeed studio the multichannel gas one it show me
C:\Users\Asus\OneDrive\Documents\Arduino\sketch_mar29a\sketch_mar29a.ino:1:10: fatal error: Multichannel_Gas_GMXXX.h: No such file or directory
#include <Multichannel_Gas_GMXXX.h>
^~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
exit status 1
Compilation error: Multichannel_Gas_GMXXX.h: No such file or directory
How can I solve this issue? Please help me with it.
Thank you
Hi there,
Welcome.
So you bought the sensor and tried to run a demo from the Wiki?
What device are you using There’s so many?
Is it a Xiao ?
Can you show a picture or schematic of the connection
Need more to help you, but My guess is two.
One, You don’t have that Library loaded that it’s trying to include?
or Your using a BSP that is not compatible?

It’s a nice sensor has good detectable low limits and fast response time, take some attention to the details to get going correctly, but worth it in the end I have seen. 
Hi @nidtin_aha
Which development board are you using?
I think it’s related to the software library not being installed properly. You can check if your Arduino Library contains the Seeed_Arduino_MultiGas library. Whether it does or not, we recommend you to remove it and re-add it.
By the way, I successfully compiled demo_background.ino within Seeed_Arduino_MultiGas library with arduino uno.
