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.
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.
