If I download the sample VoltageRationInputExample and configure it to listen to the sensor WITHOUT setting the sensor type, I get readings from 0 to 1 that vary as I move my hand up/down in front of the sensor. If on the other hand I set the sensorType to PN_1103, then I no longer get readings. Here's the code without setting the sensorType:
