I have a Raspberry Pi connected with two
ds18b20 temperature sensors.
-sensor1 is fixed on the outside of my garage (distance 20m from raspberry Pi)
-sensor2 is just connected in a breadboard near the Raspberry Pi. Everything is working well.

-sensor3, located outside and 20m from the Raspberry Pi.
Now when I type:
If get this:

Each sensor ref should be start with
What is happening with my sensors? If unplugged the
sensor1, then everything is well. If I unplug
sensor3 and let only
sensor2 everything is well.
What modification do we have to do when sensor are located far from the Raspberry Pi?
