iButton internals
I’ve written in the past about iButtons and my attempts to waterproof them. Although iButton temperature dataloggers are fairly well sealed, they are not waterproof. But if you know an old person that used iButtons in the late 90s or early 2000s, they might claim that iButtons are absolutely waterproof. It turns out that iButtons…

Waterproofing iButtons, and reading waterproofed iButtons
iButton temperature dataloggers are tiny, long-lived temperature sensors that are great for all kinds of environmental and biological monitoring, but they’re a long ways from waterproof. Old farts will regale you with tales of a bygone era when you could leave a bare iButton submerged in seawater for months at a time without problems, but…

Another R + iButton script
Previously I’ve detailed R scripts that automate the launching and downloading Maxim iButton thermochron data loggers. I’m typically doing the launching and downloading at separate times in my workflow, since I have duplicate iButtons to swap out, so separate scripts work for me. Ryan Knowles recently contributed a combined version of these scripts that downloads…

R scripts for downloading iButton Thermochron dataloggers
Last time, I posted some R code to help quickly launch many iButton Thermochron temperature dataloggers with the same mission parameters. The R code makes use of a publicly-available command line utility released by the iButton’s manufacturer, Maxim. Of course, Maxim also has a command line utility for downloading the data from those iButtons that…

Launching iButton Thermochrons with the help of R
Maxim’s iButton Thermochron temperature dataloggers are little silver doo-dads the size of a large watch battery that can record up to 2048 time-stamped temperature values. The internal battery is usually good for a few years of use. Maxim supplies a Java-based application for talking to iButtons to start recording or to download results. This program,…
