Do you need to measure Tides, or other water levels?

Shortly after starting this blog I was contacted by the folks at ioBridge.com.    If you've been reading this blog for a while (or care to go back through history), you'll see my design was based on the ioBridge sensor gateway.

Using their easy to use internet sensor interface, they built a tide gauge which they are considering turning into a product.   They asked me if I'd beta test it.   Here's a photo:

We've been running the their tide gauge next to mine for a few weeks.    Their packaging is slick, includes temperature compensation (which is important as the speed of sound in air changes with temp), and is very much weather proof.   It uses a Zigbee radio to connect back to the ioBridge sensor gateway.

The temperature sensor is in the white PVC pipe (for sun shield), and the acoustic transducer is pointed down at the end of the arm reaching out from the piling.

They have also produced a beta quality web site to display the output:

The web site is still under construction, but it does display the tide level accurately, along with a couple of weeks of history.

I've been helping them with this.   If you think you might be interested in getting one of these, please let us know emailing sales@iobridge.com.    

Although we've focused on tides, other water level monitoring applications might be interesting, such as irrigation, river flood levels, reservoir levels, etc.
