Arduino Data Logger: 2017 Build Update

If you need a logger with a rugged waterproof housing, it’s still hard to beat the crimped-jumpers build released in 2016. However sometimes I just want a quick bare-bones unit for bookshelf test runs while I shake down a new sensor. I can whip up a breadboard combo in about twenty minutes, but they stop working if … Continue reading

Switching off SD cards for Low Power Data Logging

The tweaks I discuss in the  power optimization post bring sleep current on a typical build into the 0.1-0.12mA range; leaving the sleeping μSD cards  as the largest remaining power consumer on the Cave Pearl loggers.   And those cards have been a burr under my saddle for quite some time now, as they … Continue reading

DIY Arduino ProMini Data Logger: 2016 Build Update

Its been almost a year since the last stand-alone logger tutorial, and I continue to receive questions from people adopting the platform in education settings.  That feedback makes it pretty clear that soldering is the biggest stumbling block for beginners, so I have reconfigured the build to use pre-made … Continue reading

Using the Arduino UNO for Data Acquisition

I recently picked up a ADS1115 breakout board, and it was fairly easy to use that with the serial data plotting capability of the Arduino IDE. It’s not often that something works this well on the first try, and I thought I would post about using  the combination as a kind of … Continue reading

Build your own Arduino Starter Kits for the Classroom

It’s August, and we’re assembling kits for another run of the instrumentation course.  Over time we have come to rely on 328p based microcontroller boards (aka: Arduinos) so I though I would post a list of the parts & materials we use to help others fire up their own classroom. More than … Continue reading

Arduino UNO Datalogger for Complete Beginners (ie: no soldering)

Addendum 2017-02-20: This post is the first in a series of online tutorials that I’ve been working on to help teachers bootstrap their own Arduino based curriculum. The full set are listed at  How to Build an Arduino Data Logger which walks you through the most recent … Continue reading

A DIY Arduino data logger: Build Instructions – Part 4 (Power Optimization)

The first three tutorials in this series show how to build a promini based data logger that should sleep around 0.25mA, depending on the quiescent current of your sensors and your μSD card. That will usually get you to at least 6 months of operating … Continue reading
