We have already learned how to display readings from our sensors. But if we have more than one sensor, we’ll need a way to tell the readings apart.
concat node will help us solve this problem.
Concat allows you to merge two strings into one. The new string will have the input to the left pin placed in the beginning and the input to the right pin placed at the end.
constant-stringnode in the library. Add one per string that never change. Alternatively, bind the desired value directly to a
concatpin via Inspector.

concatnodes. They will be the second part of the generated string.
Now, the readings from your sensors are displayed on the screen with a convenient label!
Try to display the measurement label before the reading and the units of
measurement afterward. Use two more
concat nodes for this. But remember, you
only have 16 characters per line.
Try to convert degrees Celsius to degrees Fahrenheit and label them accordingly. You will find a clue for this task in chapter #14.
