You have no board type un-commented, so the custom board type in Settings.h is being used.
Unless you’ve modified the Settings.h custom board type pin assignments, they will be conflicting with the pins that your sensot is connected to.

Read the “Defining your physical switch and LED” section of this topic for more info…
