    Voltmeter for computer

    well i got 2 battery's in my car
    and would like to know how much volt's there is in my 1st and 2nd battery

    now i saw on a stock pioneer radio that there is a option that u can see how much power there is in there


    i did found this on the internet but thats not really my intention to put a voltmeasure device in my car a bit a waste of equipment


    can be connected with usb this 1


    it does have some nice logs and stuff just a gadget



    my question was , does anybody has something like this also or the idea to show it on your carpc
    or know the price and adress where to get it

    thanks

    happy new year

    I'm sure the fusion brian has sensors to read voltage (as well as a million other things) or you can look at somethign like the OBDPro's OBD-II interface. As well as reading OBD engine info, it gives you (combined) battery voltage.
    I installed my carpc into my pet Kangaroo, mate.

    Mauri designed a simple voltmeter circuit that Guino added support for in Road Runner - http://www.mp3car.com/vbulletin/road...rdware-rr.html. He then later created a modified version - Update my first hardware (Serial Voltmeter).Add two new functions.

    ELM327 and J2534 diagnostic tools can measure the voltage supplied to the OBDII port. I wouldn't be suprised if it's a simple option to display it in something like ScanXL or DashCommand.

    User PPE on this forum would know if his software can be used for Voltage monitoring.

    However, this is admittedly a rather large solution to a simple question though.

    I think i bought the same thing you did but in blue. Did yours come in a blue rectangular box, and the piece itself is like 2.5 inches by like 1 inch ish tall? If so then I need your help in figuring out how to wire them!
