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...
