    hi~ i'm doing one of my fourth year course projects in EE, i need to
    design a transducer that can measure the CO2 level in the ocean, and it

    needs to be from raw matrials, but the main problem now is that i
    cannot even find the gas detector or CO2 detector in the first place,
    all the things i can find on the web is already packaged, can someone
    help me to identify the sensor or detector for me? it must be a raw
    material~ thanks alot!! ps.. need to hand the project in in two weeks
    time....please help!!

  3. How "raw" do you want ? Would a few rocks do ? :)
