Did you verify that you have power and ground on the appropriate pins of the sensor? When you say "does not give any reading...", exactly what do you see? Zero volts is a reading, just not what you expect. "does not give any reading..." tends to mkae me think that your voltmeter turns off when you connect it to the output!
Are you referring to a voltmeter reading or the output of the Arduino?
What tests have you done to isolate the problem?
