Need a 64g datalogger

I would like to purchase a KX134 accelerometer and a data logger, but it looks like there’s not a pre-coded data logger that supports that sensor you sell?

Hi Jacob (@jcorbin ),

OpenLog Artemis supports the KX134 accelerometer - with firmware >= 2.8. 2.9 is the latest.

But I can see that that the product page is out of date. I’ll ask for that to be updated.

I hope this helps,
Paul

Hi Jacob -

We’ll also get this device added to the DataLogger IoT firmware for a release in March - if you want a solution that is network connected …

Thanks for your help. I ordered the parts!

Ok, I’ve got the parts in hand. When selecting the Main Menu option 6) “Detect / Configure Attached Devices”, it says “No devices detected on Qwiic bus”. I have the KX134 sensor and a cable both from your store. There does not seem to be a way in TerraTerm to determine which firmware version you are using, but I figured I should upload v10, and this would correct the problem. There were lots of versions and I just chose one at random: OpenLog_Artemis-V10-v20.bin. However, after doing this, it still did not detect the sensor. Am I missing something? Thanks!

Hi Jacob (@jcorbin ),

Apologies for the lots of versions! The OLA firmware has been updated a lot over the years… Please see the upgrade instructions in the link below. If you load v2.10, all should be well.

I hope this helps,
Paul

Thanks, I think it works!

I would note that there seems to be a small counting error with the Hz output, as it seems to average the number of samples divided by time. At 10 Hz, the series goes: 0, 20, 15, 13.333, 12.5, 12.0, and asymptotes to 10. Adding one to the sample count in that calculation would help it at least not be a bit confusing!
