A mainstream IR sensor has 3 pinouts:

  1. Vcc: 5V power
  2. GND: Reference ground
  3. Vo: Analog/Digital voltage output

One can power the sensor using phone's mini USB's Vbus and GND (Can one?). Can one then use USB's D- and D+ pins to read the voltage from the Vo pin?

No. USB uses complex digital signaling on those data lines, that requires some digital processing power to work at all.

Using an USB enabled microcontroller to translate the output of the sensor would be one of the simplest solutions, but it needs its own program.
