Science Buddies: "Ask an Expert"

i want to make a gas sensor for co2 based on electrochemistry. So i want to know that how can we genrate potential difference with co2? like by dessolving it in to a liquid and then measure the potential difference and how will i measure the potential difference?? please give me a reply as soon as possible.

You really need to do some of your own research into this area. Have you tried putting "gas sensor for co2" into a search engine?

This sounds like an interesting project.

You can find some good information right here on Science Buddies. Try this link.

Hi,

You might also want to check out this website on capnography (monitoring CO2 in medical patients), particularly the Physics topic on the left sidebar:

http://www.capnography.com/Homepage/HomepageM.htm

It has a review of the technology principles of real time CO2 detectors.

You might also be interested in this paper on electrochemical CO2 sensors

ya, i tried to measure potential difference. and i searched about co2 but the problem is how will i got potential diffrence with co2.
i have to submit the idea in 2 days so please give me some idea as soon as possible.

Hi

Please study the link especially on Pg 73. It describes the process to measure the potential difference. Hope it helps
