The circuit arrangement would look like this:

Then fix ultrasonic range finder module as shown in the picutre below:

Insert the Module on breadboard.

Then connect the circuit to your multimeter.

OUTPUT:

If there is any obstacle near the range finder, the voltage output is near to 0V and when there is no obstacle the output is around 5 V.
