Highlighting projects we’re working on and gadgets we’ve built.
Floodzilla Gauge Network: Community-Designed Flood Monitoring
Flooding is a part of life in the lower Snoqualmie Valley in Washington. The Floodzilla Gauge Network helps residents, land managers, and farmers prepare.
Stream Sleuths
David George, a volunteer for the Angelica Creek Watershed Association, was alerted by a Mayfly Data Logger that something unnerving was happening in the creek.
A River Flood Monitoring System for Rapid Deployment
Filling river monitoring gaps requires systems with low size, weight, power consumption, and cost. Stroud Water Research Center’s ORCA fits the bill.
An Autonomous Lighted Insect Trap to Assess Aquatic Ecosystem Health
University of Wisconsin mechanical engineering students are developing a digital insect light trap to assess insect populations cheaper, faster, and better than current methods.
The “Frankenlog” Network: A Forest Floor Ecohydrology Sensor Network Using the Mayfly Data Logger
Understanding how forest floor management decisions impact ecosystem processes is difficult since long-term data on silvicultural impacts are sparse.
Hemispherical Shield to Reduce Fouling of Campbell Turbidity Sensor
Sensor fouling greatly reduced our confidence in the turbidity data. We decided to test a hemispherical shield for ease of construction and installation.
Low-Cost Stream “Tower Sampler”
We have developed a low-cost and very simple “Tower Sampler” that utilizes plastic bottles mounted vertically in the stream to collect discrete samples as various stream levels.
Monitoring Coastal Streams With the Mayfly Data Logger and Atlas Scientific Sensors
Adam Gold from the University of North Carolina Institute of Marine Sciences explains how the unique characteristics of coastal streams influenced his monitoring station design.
Construction of Water Level Monitoring Sensor Station
Our goal was to supply Comfort Lake Forest Lake Watershed District in Forest Lake, Minnesota with an easy to use, low cost, and low power system that continuously monitors groundwater levels with minimal visits to the site.
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.

EnviroDIY Mayfly logger stations deployed in PA, DE and MN!
Stroud Water Research Center staff have deployed dozens of sensor stations based on our EnviroDIY Mayfly Data Logger.
Accurate low stream depth measurements viewable on internet
Working on a remote river monitoring project with partners Cemar.org and a local chapter of The Nature Conservancy.
Mayfly boards now available on Amazon
We are excited to announce that our Mayfly Data Logger boards are now available for purchase on Amazon!
Precision Sensor Board Update
I have continued working on this project and found a probe cover and cable housing. By not using the back of the cable housing I’ve been able to modify a RM Young 41390 Sensor Junction Box and make a usable Pressure, Temp, Humidity device to fit inside the multi-plate radiation shields. I’ve made some changes to the board connections so that it will solder to the probe housing ...[Read More]
Introducing the new Mayfly Logger
It has a combination of features and capabilities that make it one of the most powerful and flexible logger platforms available.
Arduino DataLogger Board
Wanted to share my most recent attempt at a customized Arduino based (Mega2560) data logger board. I’ve used a Silicon Labs CP2104 USB interface and also contains: -DS3231 RTC with Battery B/U -uSD Card -4MB MRAM (SPI interface) – 3 Serial Port Headers (3.3V/5V) **I left Serial dedicated to the USB, but Serial1, 2, and 3 are avail. -3.3V/5V I2C headers -3.3V/5V SPI headers All digital...[Read More]
Precision Sensor Board
I recently designed a board that incorporates digital pressure, temperature, and dewpoint sensors I’ve called the PTU board. I deal with weather balloon tracking systems and the information sent back from the radiosondes is usually called PTU data (Pressure, Temperature, and Humidity). I’ve written 2 new Arduino libraries for the pressure and temp and reused an existing library for the...[Read More]
16-channel data acquisition system
A few months ago I was asked by a researcher here at the Stroud Water Research Center to come up with an automated way to measure the voltage of 8 fuel cells. The cells need to be electrically isolated from each other, so that requires differential measurements instead of the more common method of using a common ground for everything and then just doing single-ended measurements. I looked into c...[Read More]
