Where can I find more information about the Ultrasonic Sensor?

Are the schematics available online? What part is used? Can you point me at the datasheet for the part?

Thank you.

Hey WPD, not sure where it can be found! We buy them off the shelf from Seeed.

Checking their wiki, it doesn’t look like they have a schematic for it: http://www.seeedstudio.com/wiki/Grove_-_Ultrasonic_Ranger
