    Can you email me your code at mayfly@envirodiy.org so I can take a look at it?  How many other adafruit ADC boards do you have attached to the Mayfly in question and are they the 12-bit or 16-bit versions?  The Mayfly’s ADC is permanently set to 0x48.  What is the typical and maximum voltages you should see on the sensor?
