I am trying to create a detector to see how much carbon monoxide is in a room. I am looking to find an specific average throughout a day, not just if the carbon monoxide level is too high.
By the way, I am doing a project on Indoor Air Pollution.
Thanks in Advance.

Most Carbon Monoxide detectors determine the amount of CO present in the air by using an electrolytic sensor. If the value is high, the alarm sounds.
There are digital CO detectors available which will read you the level on an LED number display. You can write down the numbers on the display at predetermined intervals and average them after 24 hours has passed. Most houses should read 0 all of the time. I've only seen mine say something other than 0 when I was working on the car in the garage and had it running for a couple minutes (with the garage door open although still allowed enough into the house to cause it to display, but not alarm). Take a look just past halfway down this page and you will see a couple models with a digital readout on them:

Oxygen and Carbon Monoxide instruments?
Q. I need to read levels of gas. What am I looking for?
Answer
Industrial Scientific sell T80 and T82 carbon monoxide monitors. They are a little bigger than a packet of cigarettes and can be worn by the user. The T82 has a data logging function as well as the usual Peak, STEL, TWA values.
The unit (I think) can do oxygen with a change of sensor.
It is also possible to get multiple detectors in a single unit. Combined CO, O2, H2S and LEL measuring units are common.
Search on the web for "T82 carbon monoxide monitor" to get a local safety supplier.
