stress..sharp sensor!!GP2D15

i'm using sharp sensor as mentioned to detect presence of object in order to stop the conveyer. before this i'm using  GP2Y0A21YK and because of the phsyical appearance alikeness, i thought the basic operation is same.but i just discover that the new one is based on digital output. i try to modified my circuit. but seems nothing change happend. i dont know what really going on.. is there anyone that familiar with this sensor. my presentation day is about 2 weeks and i am even doesnt start to integrate the whole system yet...please..tq in advance

Sounds like it's being pulled low for some reason.  A schematic would definitely be helpful...

Can you post a schematic?
