1 wire time on

[auto_man]

hi, I was wondering how I could measure the amount of time a device was on using 1-wire. My thoughts were to use one of the 1-wire a/d chips then looks for voltage vs no voltage and use the pc to check for time on/off. My concern with doing this is that it would only be accurate to my poll time which is currently 5minutes. I would like a better resolution.

Any ideas? I really would prefer not to change my poll rate not that I can't but even changing it my data would be slightly inaccurate. I would prefer to have some other method so I can be as accurate as possible and still poll at a 5 minute interval.

Thanks!

At this time we don't have a solution that would work for what you want. All of our devices require the mater to poll them to get the data. You could potentially use a DS2423 counter to count pulses and then create some circuit that would generate pulses every X seconds while the device was on.

I saw something similar on the Internet somewhere but I don't have a link.

Yeah I thought about that, but I was just trying to be lazy and didnt wan to change my current software. That way I would still get my temp and other measurements I have on a 5 minute interval. I will think more and see what I can come up with.
