Hi , may I know what is the code to run the Air Quality Combo to measure Co2 and the libraries needed to be downloaded in the Arduino software ?
Is this to measure Co2?
There is error in this, what is the correct code to get the display for Co2, Humindity, VOC and PPM to appear
you have the wrong code. Look at the hookup guide Introduction - SparkFun Indoor Air Sensor SCD41, SEN55 (Qwiic) Hookup Guide

I check on the hook up guide and we cannot find any solutions . Can help guide me because I’m very new here ? I don’t know how to navigate the hook up guide , really need some help . We can’t find the exact code to display Co2 , Humidity , PPM and VOC .
download and install the software in the IDE and select one of the examples: Software Setup - SparkFun Indoor Air Sensor SCD41, SEN55 (Qwiic) Hookup Guide/ software

You’ll navigate the hookup guide by working through the Table of contents on the left side of the screen; it looks like you should head here Software Setup - SparkFun Indoor Air Sensor SCD41, SEN55 (Qwiic) Hookup Guide to double-check you have all 3 installed and then click ‘examples’ on the left to begin working through/reading along with them
Please follow all the instructions given by TS-Russell. I believe that will solve the problems. By the way, if you are new, I think you can first try the MQ series of gas sensors.
These are simple to use and can detect different type of gasses. To verify the data you get from air quality combo, you can always cross check them with MQ sensors’ output.
