fpga +cpu + wireless

[Srikanth Anumalla]

Hi

I am quite new in this field, Please excuse me if I talk something
nonsence. I have 10 pressure sensors which measure pressure in 10
different points in a field. I need to aggregate all these values in
realtime and send to a remote computer.For this, somebody suggested me
to use fpga, I made little research and found out that we can actually
run an some programs on fpga. I have this idea now, to build an fpga
board which can read data from the sensor and send that data to a
central computer in the field over a wireless network. and I will have
an fpga at each sensor. CEntral computer will aggregate the data and
send to a remote location via phone line etc. For this to be realized I
have to know whether an fpga is capable of collecting date from a sensor
and send the same data over a wireless network. Please give me pointers
on this . Any help would be greatly appreciated.

Thanks
Srikanth

If your pressure sensors have analog output, then why use FPGA?

Use a PIC micro with build in AD and 4 channel input mux.
3 of these or one with an external mux, use the serial port of the PIC
or make your own protocol or whatever.
12F675 is only 8 pins DIL, has a 10 bits AD with 4 input mux, internal oscillator,
costs 2 dollars, so 4 of these set you back 8 dollars and the microchip tools are
free from www.microchip.com
Why use FPGA?
