I got this sensor off Amazon. It was fun to play with but surprisingly difficult to get meaningful results from. The difficulty is primarily due to sensor limitations. There are quite a few sites with Arduino code for this sensor, I am using a MSP432 LaunchPad here. I wanted to keep it simple and use the pulseIn() function. It works with the MSP432, but not so well with the F5529. A better approach would be to use a timer and count interrupts from the pulses.
See my git repository here for the pin connections, code, and a deeper discussion.
The following is a photo of the sensor I'm using and some examples of what you might expect:
