CO2 Sensor MH-Z19B

is there a MH-Z19B CO2 sensor? I) need it for my final exam and I can’t find it anywhere so if anyone has the file I would be grateful.Thanks in advance!

Good morning,

Is this the component you mean?

MH-Z19B on Funduino

Regards, Harald!

yess it is. does this component exist as a fritzing file?

Unfortunately not…

It would have to be replicated. I found a diagram for it.

MH-Z19B

I could start on the diagram, but that would take a while…

Regards, Harald!

@RAPTOR7762 can I use the two files as a basis and continue working on that part?

MH-Z19_breadboard

MH-Z19_pcb

…or do they contain errors?

Regards, Harald!

Hi @Harald_Rau fixed them

In breadboard view, your first 5 pins were inverted, next 4 missing. Corrected and replaced them above

Ok, thanks.

I’ll read through your tutorial first…

So, with your two parts and the Inkscape extension, it worked quite well.
Unfortunately, the original part has no visible labeling. I could put the connector labels on the housing?
However, when you hover the mouse over the connector, the label is displayed.
I hope no major errors have crept in.

@RAPTOR7762 I’ve made some further improvements. However, I did the merging with the Parts Editor in Fritzing.
It seems to work, but the editor does alter the SVG files a bit.
