carbon monoxide detector says 0 image
kyorge6293
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:

What does it mean when my carbon monoxide alarm says the "Peak Level" is 26? Is this cause for concern?

It never actually sounded, but the Peak Level went from 0, to 15, to 21, to 26. (There's a button you can push called Peak Level) So, does anyone know what this means? Do I have a slow-leaking source of carbon monoxide, or is my alarm just detecting other similar chemicals? As a side note, the alarm is in the kitchen, not in the ceiling, but on a counter.
Answer
The highest level it has detected is 26 parts per million, most will not alarm till 50 ppm. Get it out of the kitchen, simply cooking could cause the reading. I recommend you put detectors where you sleep.
Carbon monoxide is known as the silent killer because most become victims while they are
are sleeping. Candles, burnt food, gas stoves, auto exhaust, gas water heaters and gas furnaces are examples of things to look for. Exposure to over 5ppm is not recommended for any length of time. It is also possible your detector is faulty, I would not bet on that. Take the time to sort this one out.
