} Can anyone help me check if the code for IOT sensor is correct as we need to connect to Blynk and do we need to installed any libraries ?

i am trying to do something similar as well

Have you gotten the basic examples for each working first? Hook up just the screen and get its to begin outputting AVR-Based Serial Enabled LCDs Hookup Guide - SparkFun Learn

Then I’d move on to do the same for the IAQ sensor https://docs.sparkfun.com/SparkFun_Indoor_Air_Quality_Sensor-SCD41-SEN55/software_setup/

Then move on to getting both to work at once over serial, and finally integrate the whole shebang into your Blynk
