Dust sensor Sharp GP2Y1010F

I need to now everything about the Dust Sensor Sharp GP2Y1010F, I try to find information about it but is really difficult to find something that makes sense. Some information says that I shoud use some resistor to conect the sensor and others shows the conection with only the sensor, so I need to know how to conect and program de sensor with the arduino. if someone could help I'll be glad.
