Building a Low-Cost Electrical Conductivity Sensor Using the Mayfly Platform

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.

New tutorial: Learn EnviroDIY Programming

I’m a scientist with a limited amount of coding background and an even more limited understanding of electrical engineering, and EnviroDIY Modular Sensors on GitHub has made Arduino framework environmental monitoring possible for me. This blog post will point you to a tutorial that is intended to get end-users like me doing Arduino framework environmental monitoring like a pro. The Arduino Revolut...[Read More]

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 version 0.3 bugs

A few weeks ago we found that some of the version 0.3 Mayfly boards were assembled by the manufacturer with an incorrect voltage regulator on the section of the board that generates the switched 5-volt boosted supply. This error does not affect any other functionality or features on the Mayfly.  The only issue is that you will see 3.3 volts on the “Sw_5v” pin instead of 5 volts. We hav...[Read More]

Trigger Teledyne Isco Sampler by Campbell Logger

Hello! Anyone has experience with triggering a Teledyne Isco Water Sampler external by a Campbell Logger? It seems to be a small challenge and we are happy for any information!

What’s that sensor measuring?

Wow what a great place to share about sensors. My passion has been the interface between the real world and the digital domain. The world as we know it always has layers – so while we aim for a visualized story of some aspect of the real world – say temperature or stream depth– there are many aspects of collecting the data. Last year I bought a Honeywell Internet thermostat that allows me to see a...[Read More]
