I’ve been working on something similar, though smaller in scale (just our farm in western Washington State [USA], between Seattle and the Cascade Mountains. I’ve been experimenting with the MB7040 I2CXL-MaxSonar-WR sensor, Particle.io Photons for MCU, communications and cloud connectivity along with Weather and Battery Shields from…[Read more]

I had already been thinking about measuring temperature at the top, bottom and water surface [hopefully using an I2C-IR sensor I’ve been playing with] in the stilling well. From there calculating the thermal gradient and applying a calibration curve shouldn’t be too difficult, just…[Read more]

I wrote up a bit of a concept paper for what I’m hoping to do and posted it at http://toms-wow.blogspot.com/2015/01/open-source-crowd-source-stream-gauge.html

What are…[Read more]

And perhaps some sample data? Also info on how the sensors are doing through the winter, would be helpful.

I think I want to build and deploy a couple to test for potential use in community driven local flood monitoring and forecasting in the lower Snoqualmie Valley (outside…[Read more]
