Bluetooth Connected Data Logger?
« on: February 23, 2017, 02:07:46 PM »

I'm looking for a cheap (< $200), simple (1 or 2 channel) Bluetooth connected voltage data logger that I can read and control from an app on an Apple mobile device. Such a thing surely exists but I have had nothing but frustration searching for one. I would very much appreciate any leads. Thanks.

Best,

Does it have to Bluetooth? Plenty of options using WiFi protocol.

WiFi would be OK, too. But Bluetooth is my first choice. Less range but also less fuss. Thanks. -F

Haven't tried it, but it seems pretty cool!  Looks like it's around $137 on amazon.

I may just have to order one. I'll sleep on it. Thanks so much. -F

I have a couple of these I use in my day job:

I haven't tried their Wi-Fi option but the basic USB loggers work great, available on line here:

Dave, thank you. The little OEM modules are nicely priced and might be good for some future projects.

For the current problem I went ahead and ordered a Mooshimeter, which I should get on Thursday. I'm probably more excited about it than I ought to be :) I'll let you all know how it works.

Best,

I'll let you all know how it works.

I got the Mooshimeter -- and so far I'm in love. It's in a nice little package and came to life right away. Test leads (3), batteries, and a zippered case are included, but to do logging you need to supply a micro-SD card (~$20 for 32 GB). My only gripe so far, and this is very minor, is that the common and voltage banana jacks are on a diagonal and not at .75 in. spacing, so you can't use a double banana for the most common logging application. Current and resistance, however, are on .75 in. spaced jacks.

If you ask it to log it generates an email with a .csv file as an attachment, like this:

PCB: 008
ASM: 000
LOT: 00000
FW:  1477971088
CH1:  AMPS   10A
CH2:  VOLT   60V
SMPL: 0032 0125Hz
UTC TIME SEC  ,CH1 AMPS DC  ,CH2 VOLT DC 
1488489656.232,-1.442432E-05, 1.006439E-01,000470       
1488489656.666,-4.327297E-05, 1.009737E-01
1488489657.666,-1.923242E-05, 2.172455E000
1488489658.666,-3.365675E-05, 3.831762E000
1488489659.666,-2.884864E-05, 6.951432E000

It also has a graphing function in the app, which works like an oscilloscope in scroll mode, but as far as I know you can't get it to graph the logs. This would seem to be an obvious add-on. All for now.

Best,

--Frank
