Connected sensor on breadboard and with nothing connected to either port the 1 volt on the analog out pin floats around randomly about 200 millivolts either side of 1 volt. The 5 volt pin is rock solid. Is this normal for this sensor?

Well it may be defective if its been dropped, i saw somewhere that these things are very sensitive and you cant drop them even if they in a box, check the datasheet to verfy
Hi Carter,
Make sure you voltage source is nice and steady.
The analog out point should not fluctuate, unless you are outdoors and the wind is unsteady with gusts.
Indoors, on a test bench, it should remain solid at or near 1V.
Either the sensor is defective or the filtering hardware on the breadboard is defective.
Contact Jordi at the DIY store , he should be able to help you out.
