Increase Data Quality From Your Meter Hydros 21 CTD Sensor With These Tips

Regular cleaning of your EnviroDIY Monitoring Station sensors is the most important step in making sure you are collecting meaningful data.

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.

Protecting EnviroDIY Monitoring Stations From Beaver Damage

One area of vulnerability for EnviroDIY Monitoring Stations is rodent damage and in particular beavers. Beaver tend to bite anything that gets in their way while in the water and they have very sharp teeth!

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.

Building a Continuous Temperature Logger with the EnviroDIY Mayfly

This document outlines what you will need to build a Continuous Temperature Logger with the EnviroDIY Mayfly Data Logger. This is a great EnviroDIY starter project and utilizes the Mayfly Data Logger and a OneWire Temperature Sensor.

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.
