Hello,
I bought the “Infrared C02 Sensor V 2.0” and i put in arduino software the code that DF ROBOT propose here:
https://wiki.dfrobot.com/Gravity__Infrared_CO2_Sensor_For_Arduino_SKU__SEN0219
And when i try the read the measured data, i see that (in the com):
Could you help me? I do not understand why i cannot read normaly datas

Baud rate mismatch. Kindly make the change as per NeloKin's instructions.

Hi
Could you please change the baud rate here?

According to the WIKI of Gravity: PWM Infrared Carbon Dioxide Sensor (400-5000 ppm)(SKU:SEN0219), if you are using our demo code, you should change the baud rate to 115200.
Hope it can help.
