Example for SPEC CO Gas Sensor with Arduino?

[salmanfarisvp]

Hi, Do you have any example for reading CO ppm value in Arduino ULPExample_1sensor.ino requires an analogue addon, so is it possible to measure without the addon? Thanks in advance.

I'm sorry I don't understand the question. What 'analogue addon' do you mean. Is this a software or hardware question?
This program requires an analog sensor, for example here: http://www.spec-sensors.com/wp-content/uploads/2016/10/ULPSM-CO-968-001.pdf
Also there is a developer module that works the same, but has a buffer for unstable supply voltages/ battery/ and voltage regulator here:

Also,
I have a new version of this library. The best Arduino to use is the Due, because it has a 12-bit ADC, all other Arduino have only 10 bit.
I'm not very skilled with github, so I do appreciate your edits, which I merged, hopefully I did this correctly.
Thanks again

I have a CO – Carbon Monoxide Sensor 1000 ppm Pinned Package but I think in order to work with the library I need to use the Analog Gas Sensor Module for Carbon Monoxide: ULPSM-CO.

and Is it possible to use CO – Carbon Monoxide Sensor 1000 ppm Pinned Package alone with Arduino to get a reliable reading?

I have a new version of this library. The best Arduino to use is Due, because it has a 12-bit ADC, all other Arduino have only 10 bit.

Can you please share the link to the library!

so I do appreciate your edits, which I merged, hopefully I did this correctly.

Thank You for sharing your work too 🤗.

Can you look at this post and tell me if this is what you have? This is for low resolution detection of high concentrations of CO. If you want higher resolution and stability, you do need to get either the digital or analog module, or build your own analog module using our open source files.
