The arduino does not establish a serial communication with the NodeMCU

Hello.

What happens is that I plan to connect several sensors and I want the data to be sent to the NodeMCU and through this board, store the data in a csv file in the cloud

what are the sensors? what interfaces required? do the sensors have 3.3V or 5V interaces?
e.g. if I2C you can connect several sensors to the same I2C interface
