sensing 5 volts from an infrared sensor ( 0 or 5 volts DC ) (separate power sup

Archiver

Thanks,
The schematic is easy . But do you know about the
Basic Stamp command for this ?

The sensor has +5, gnd, signal.
I 'll try to join GNDs but I am not sure about the
command .

The sensor gives me 0(off) or +5(on) .
(it is a simple sensor)

Any suggestion please ?
