Hello everyone!
I am new to working with Grafana. The goal is to display the concentration of the air as in PPM, but as far as I understand, Grafana is only displaying the raw data from the sensor. I wanted to know if I can make the conversion via the Transformations feature in Grafana or has to be directly in my Arduino code?
Regards

Can you share more about the kind of transformation you want to do. For example, what does your raw data look like and how do you want it to display? Which type of panel are you working with?
If you can, please follow these steps to share your raw unformatted data? That way, the community can try and mock up your problem
