Use the cable-tie to fix the sensor cable to the rebar ensuring that the metallic section of the sensor does not touch any rebar or frame. The sensor should be placed ensuring that you can plug it in easily to a Node, and that the Node can be located in a safe place. The Node should be kept off the floor to avoid water pooling around it, and should be orientated with label the right way up and sensor exiting the bottom of the Node.
