I have a question regarding ultrasonic sensors. Let's say for example I want to use a typical ultrasonic sensor, in this case lets say: http://www.jameco.com/webapp/wcs/st...toreId=10001&catalogId=10001&productId=136653 in a circuit for distance detection. How would I hook it up for use? Or if someone could direct me to a resource or something that could help me understand how to place these things in circuits. Im fairly new to the sensor area in EE. Do I apply a voltage on one end, and expect as response voltage on the other? Thanks in advance guys.
