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
