Does anyone know of an inexpensive way to measure and capture Carbon Monoxide and Other Air Pollutants in Air and capture in PC? I don't where to begin. Does anybody know and have advice where I could begin? I am new to this stuff and don't know where to start!!!
 
I am also new to this and am quite interested in what you learn here. There are several companies who make CO Monitors for high pressure breathing air. I believe they use regulators, restrictors etc to reduce the pressure to low pressure so they may work for what you need. One company is in Round Rock Texas: [email protected]
Another is http://www.topac.com
And one more is http://www.pioneer.com
There are others but I can not think of them now.

Hopefully one of these can help you or lead to someone who can help. I am doing some research on the same subject so If I find out anything I will try to let you know.

Depending upon the instruement your using, (or that you select), the device can have or could be equiped with a serial port, it then be a simple matter of reading the data from the device to th PC via the serial port. Perhaps the device has a voltage or current output, with the appropriate AtoD card, you can then read the data in that way. In either case a little software to log and time stamp the data would be required. For AtoD cards, the loging software is probably included, will also have trending and related functions - LabView as an example.

This is relatively common place and should not be an overly comlpex problem to solve. Do a little research on the internet, you will be amazed at what you will learn to help you solve your problem.

You could look at http://www.figarosensor.com/gaslist.html. They make CO sensor. You'll have to make your own circuit but it is not difficult. Follow the included application notes. You need to be able to read voltage from your computer and make some calculation in order to convert the Log vs Log response of the sensor to known value.
