+/-10V inputs 10-bit resolutionIs 19.5 mV resolution good enough for you?-- Michael KarasCarousel Design Solutions

Rich Webb · Answer

We have one at the office but I prefer one of these . Runs

12 bits, single (8) or double (4) ended with the differential mode gains settable from +/- 1 to +/- 20 V. We use the low-speed model (1208LS) for temperature monitoring runs (w/a thermistor), and for battery monitoring or similar. One thing that I very much like is that it comes with the interface DLL so it can be easily integrated into your own lab apps, with its internal I/O ports or a serial, USB, or GPIB running things and the module recording the results. Pretty handy.

What I really hate is the goofy shape and the un-labeled connections. A fine-point permanent marker suffices to label the terminals but it looks a little tacky. Works fine, though.

Ppffftt. All I want to do is monitor things around the house withsomething cheap. I was thinking of building a datalogger based onwhatever the current Microchip USB kit is, but then I saw this thing.

Thanks, this looks like an interesting alternative. I am just lookingfor something cheap for home monitoring of appliance duty-cycles,temperatures, battery cycling, etc...

************************ I got their DI-194 for free several years ago. I played with it for a while and it seemed to do what they claimed. It was not a rigorous quantified evaluation though.

srgdsI would just use a PIC (for example: Atmega88 or PIC32MX) to do it.Use RS232 to run the distance and USB/232 at the PC/laptop side.  I amalso looking into cheap bluetooth adapters, but software driver at thePIC side is a problem.

Davej · Answer

I admit the PIC approach is certainly far more flexible, but it wouldtake quite a bit more time and effort.
