How to get voltage sensor data into a PC

    I fly an experimental plane and would like to have a small on board PC
    display
    many of the analog sensors in the plane, exhaust gas temperature,
    cylinder head temperature, oil temperature, outside temperature, oil
    pressure, fuel pressure & tach. With the exception of the tach all
    sensors report the readings as a voltage.

    Any ideas on how I can get a half dozen different voltage readings
    into a PC in real time?

    Cheers,

    www.dataq.com Low-Cost data acquisition starter kit. $24.95 for
    the hardware, software, cable, documentation, even the screwdriver
    for the little screw terminals. 4 low speed analog channels +/-10
    volts 10 bits resolution, 240 samples/second, and 2 digital inputs,
    chart recorder and waveform viewer software included. ActiveX
    controls if you want to write custom windows code, you can even
    control it from inside Excel.

    If you are doing slow speed modest resolution sensor measurements
    then this is going to be lots better than trying to figure out how
    to deal with an AC coupled sound card or trying to build something
    for this price.

    There are lots of other similar products that are faster. They
    usually start at the $100-$200 and up prices.

    I don't work for them, I just get their ads in the mail.

    Thanks for the link. It looks good but it only allows for 4 inputs.
    I found a nice site at
    http://www.iguanalabs.com/adc2051.htm
    which talks about how to get one data source in. Ideally what would be
    nice is to send a signal over the serial port to specify which sensor
    of 8 to monitor and then listen for that data.

    Any ideas anyone?

    Thanks
