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
