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.

Geographical Scaling Modular Sensors

Modular Sensors library of sensors interfaces is fantastic. Sara’s classes form a backbone of data flowing from the sensors to the cloud(s), all running on the low cost, solar powered Mayfly. Thanks Shannon and Sara and many others who help teach about Modular Sensors. I was able to extend the Keller Acculevel Class to a Keller Nanolevel device easily, and I’m working on the Insitu SDI-12 interfac...[Read More]

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.
