i checked the image now... if your output sensor is a pnp transistor
you could put it directly to ds2406 5v and some resistors to pull
up....
if it´s not in same power circuit than ds2406, you will need a
optocoupler, to don´t build a brick

Virtualization & Cloud Management Using Capacity Planning
Cloud computing makes use of virtualization - but cloud computing 
also focuses on allowing computing to be delivered as a service.
