5VDC Waterproof Ultrasonic Range Finder
This module comes in two pieces, the first piece is the probe that can be submersed in any liquid that is non-corrosive. The second module is the logic board that should not be submersed in any liquid and interfaces the probe to any Microcontroller.
Connect the probe to the logic board and hold the board with the pins facing towards you, the left most pin labelled 5v goes into 5v on your Microcontroller. The next pin Trigger goes to digital pin 3 and Echo to digital pin 4. The final pin GND goes to ground.
