Interface TGS3870 (methane and CO) sensor with arduino

Hi all. I am new to the forum and I have basic knowledge of electronics. I am trying to build a small project to to air quality monitoring with arduino and different sensors. I have an Figaro TGS3870 for detecting both methane and carbon monoxide that I would like to interface with arduino. Here are the specs for the sensor.

I have run few google search but I cannot find any material that explain how to do that. I was wandering if some of you can point me in the right direction? Thank you in advance


it seems to be an analog sensor. So you have to build the circuit on the datasheet and then use such things:

The working link is here:

You will have to adapt the coefficient.

And this:

I can’t send pdf here unfortunately

@pjg Thank you very much for your replay. I will have a look at the circuit. I guess this is the only way to interface it with the Arduino…
