I see.
There is a host of ADXs but I think most will work with any voltage between 3 and 5 volts, so this is just fine.
The BrometricSensorTutorial is not so good. It would be better to use serial resistors as explained in the SparkFun article I linked to above.
The reason why all those designs work and people are unaware of hidden issues is, because only short pulses (of 5V) will be on the lines. This is "stress" - so to speak - for the 3 volt device, but not necessarily fatal...
In any case it must be avoided to wire a constant current of >200uA of 5 volts to a 3 volt device. 22k to 47k resistors will provide ample protection
