    Hi Shannon, thank you again. We were finally able to get a voltmeter and test the connection. There is voltage being applied to the sensors when the channel scanning sketch is running, but the program still says no sensor detected and to check the physical connection. We have tested both sensors. Could there be an issue with continuity? We have our data point at 7 and our power at 22, just making sure that is correct as well.
