Multiuse Temperature Data Logger compatible with Debian

Postby 1byte » 2019-03-13 09:39

Is anyone aware of any cheap commercial/open source "preferably USB" "Temperature Data Logger" that is compatible with Debian?
Export to LibreOffice Calc/Writer/TXT/PDF
Record capacity 1-2 days minimum. (1-5 min intervals)
Multiple use :)

check out https://www.sparkfun.com/

This kind of stuff seems to need a kitchen, DIY.

Without a little more info, there are a number of ways you can go. Here are a few...

If you are using a Raspberry PI, then you don't need USB. Look for an SPI or I2C model (I like using SPI devices when possible; long story). Here are a few examples you might consider:
[*]https://www.adafruit.com/product/2652
[*]https://www.adafruit.com/product/3251

If you are targeting a desktop/server, then you could also connect the above sensors to a cheap Arduino. Then connect the Arduino to the desktop/server via USB.

Why would you choose one of the above solutions?
[*]If you have hard realtime requirements (e.g., you need the samples to occur exactly X milliseconds apart), then the Arduino is probably the best cheap solution. With an Arduino, there is no operating system, so you have complete control over timing. I know you want to sample every 5 minutes, so I doubt this is the case, but I want to mention it for completeness.
[*]If you want to collect temperature (and maybe other environmental data) from several locations, then several Raspberry PIs connected via WIFI/Ethernet would give you a cheap monitoring solution.

Having said all of that, I suspect the above is a little more hands-on than you might want.

It (the question) is not clear enough really, mostly because the OP does not state clearly, what kind of tempature data ? Could be weather, and daily temps, or maybe a engine, and the temperature data, ahh, or is it CPU, and PC temperatures, ?
"Multiuse", hmm, maybe try using a thermometer, and create a file, type in the readings whenever you want, then export them to libre office or where ever,..
There is this software:https://www.digitemp.com/software.shtml
=====
https://github.com/bcl/digitemp
(I actually use it myself) it is open source, and free, which is much better then any commercial ,closed source blobs, I use it to control my incubators,and also log the temperature fluctuations, there is some instruction here:
https://www.instructables.com/id/Temperature-sensor--weatherstation/
All though it says "weather station", the instructions can be applied to a variety of things, as in my case, I use it for my incubators, and keeping records on them.
Some friends of mine also use the above to trigger alarm on the PC, if and when the temperature is dropping, and getting to close to freezing, there are sensors in various parts of the orchard,..but any way that is another topic.

I'm going to put this on my agenda for someday. I'd forgot that I did some projects with a 'fusion brain' but that was XP and alpha. At the time there was a Canadian company making general usb io boards that had some linux dev files. That's a decade ago, I forgot, still have a some stuff, yes, on the agenda for someday!

I have a few pymcus http://circuitsforfun.com/pymcu.html, which has analog and digital I/Os, pwm. spi, 1-wire, lcd-controller and others. Has been great fun. Raspberry PI can do many of those on its own, or with add on boards. I have two PIs. Currently one pymcu is connected to PI to measure plant moisture, air humidity and temperature. ChipChap2 http://circuitsforfun.com/ChipCap2_Breakout.html does those latter two.

Cool stuff. Some issues from past experience are the lack of clear operating temp specs and current capacity. I was working on multi sensor input 'vote' controlled fan controller to continuously vary the speed of two 38A 14.4v cooling fans. Kinda locks me out of hobby grade stuff. Another project still out there was a similar logic system for controlling draw on a AC line according to capacity, ie 40A of stuff on a 10,15,20, or 30A circuit.

But right up the Op's alley is studying environment variables over time in architectural models.

My back burners are now full.
