Arduino based water quality measurement by IO-Rodeo

I had the joy of traveling to Bhutan in November 2015 with a delegation from Stroud Water Research Center and Waterkeeper Alliance. Among our goals was to provide our Bhutanese colleagues at Clean Bhutan and government agencies with water quality monitoring tools and methods that are low cost, accurate, sustainable, and adaptable to their needs to help them monitor their own water quality.

Testing equipment to measure water depth accurately in low flow applications in surface water streams.

Measuring low water in streams accurately

To recap from a previous blog, a project looking at effects of drought conditions is monitoring the low water depths in-stream, with transducers that have a capability of reliably measuring changes of ±0.01’(feet) in low water conditions, connected via an open interface 4-20mA  to an Onset U30 cellular wireless logger. For reliability,  it was decided to use two water transducers per logger. Over ...Read More
