Did you include the capacitors that are in the datasheet? Omitting them would certainly cause erratic readings.

The 47nF cap between 0V and 5V isn't necessary because the arduino already has a much larger cap between its 5V and ground. But the 4.7nF cap between output and 0V will no doubt smooth out signal irregularities.
