Make sure everything is out of the way between the sensor and the wall(including the tape measure you're measuriung with). Make sure your wall is flat and big (don't do it near doors, etc). Make sure your sensor wires do not go near any motors or the radio.

Also, increase the oversampling and averaging. That will settle the sensor noise and improve your accuracy.
