eTape water level sensor

Hi all,

I'm working on a project to monitor the water level in a funnel (to prevent overflow). I've just started and am at the point where I want to just power the sensor and connect it to the Arduino to play with.

I am using an Arduino Leonardo.

The eTape documentation says that it needs 6-32V input. My understanding is that the Arduino only provides up to 5V. Do I connect an external battery? How would I do that? The eTape sensor has pins for Vin, Vout, and GND. I'm assuming I would connect the battery to Vin and GND and the Arduino to Vout. Is that right? I'm completely new to electronics.

Thanks!

Right, and connect the battery negative to Arduino ground so Vout has a reference. The output from the E tape will probably be more than the maximum input to the Arduino so that will need to be dealt with. Voltage divider, perhaps. A link to the particular sensor would enable us to be of more specific help.
