The calibrated response

In order for the sensor to work, you need to adjust the potentiometer so the blue trace is [i]just above[/i] the yellow trace. When the knob is touched and the blue trace falls, it will be sure to go below the yellow trace. You can do this by turning the potentiometer until just after the alarm goes off.
