It's a case of RTFM here CM!
Have a look at the DATASHEET on the Rev-Ed site. Basically you tell the SRF005 to send a pulse (output pin) and then measure the length of the pulse it returns to give you the range (input pin). The program's in the datasheet
Make sure you choose the right connections for the 20m. It's done differently for the 08m as it uses the same pin to trigger and read.
