Sensor fouling greatly reduced our confidence in the turbidity data. We decided to test a hemispherical shield for ease of construction and installation.
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!
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.
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.
A low-cost electrical conductivity sensor using the Mayfly platform was developed in part to support efforts to study the effects of stormwater runoff into Great Marsh in Chester County, Pennsylvania.
