The pad wear sensor is a simple dedicated contact sensor. When the pads are worn to the threshold thickness, the sensor makes contact with the rotor and a part of it wears out, a curcuit is closed, and the red brake light on the dash comes on.

The I-drive reading has nothing to do with that although it can also trigger the brake light on the dash (I think it goes yellow first). I assume it processes data from some of the other sensors such as accelerometers, and/or speedometer to predict when you need to replace your pads, and is not all that accurate when the car experiences track conditions.
