Gas Sensor Used With Ezb V4

Hello everyone,
I am considering using sensors which can show the quality of air, like detecting any toxic gas.

Does any one have any recommendation?

I have two requirements: 1. Use ADC ports. 2. Decent performance.

Right now, I am applying MQ135 sesnor, which does not impress me much, with its poor performance.

Also any tips about using a gas sensor with ezb v4?


Upgrade to ARC Pro

Harnessing the power of ARC Pro, your robot can be more than just a simple automated machine.

Steve G put a gas sensor in his K-9 robot.

Here is the discussion thread for the sensor: https://www.ez-robot.com/Community/Forum/Thread?threadId=6342&page=2

And his project showcase where he describes the final configuration including discussion of the sensor (begins on page 4 I believe):

(fyi: The search engine here is not the best for searching things like this. It found all 1400+ threads with the word sensor and where gas was part of a word, but the site is indexed by Google. I did know that I was looking for it which helps, but this is the search I used in google to find the specific threads: http://lmgtfy.com/?q=site%3Ahttp%3A%2F%2Fwww.ez-robot.com%2FCommunity%2FForum%2F+%22gas+sensor%22
(don't be insulted by my use of "let me google that for you". This forum also interprets some characters as smilies or links that aren't, so the search string would not render correctly. I was not telling you to search before asking a question).

Thanks, @thetechguru


Of course, I have done my search in ez-robot forum before I did this post. However, I did not find valuable information on the first two pages returned. That's why I start a new discussion and make my question public.

Thanks for sharing your method of searching. That really helps.
