Let's see how to mount the CO2 meter with a sensor Senseair S8 LP.
This is going to be a very short article, only with the important differences from mounting with the MH-Z19B or MH-Z19C sensor. We will go "Straight to the point«.
If you haven't seen the article «A homemade CO2 meter with Wifi against the coronavirus«, You should see it now since this montage is based on him. Almost everything is the same and here we will only deal with differences.
Why use the Senseair S8 sensor?
I think the correct question would be, why mount a CO2 meter with another sensor?
There is several important reasons What can I think of to use this sensor, instead of the MH-Z19B or MH-Z19C.

- Provides more accurate measurements
- Has longer duration
- For the moment no fakes
- Gives less problems with food
Similar in assembly
The construction of the meter with this sensor is practically identical. The sensor is very similar, it has almost the same physical form and the connections are the same.
For all the assembly part, you can follow the tutorial «A homemade CO2 meter with Wifi against the coronavirus«. The connections are exactly the same.
The differences in the meter mounting are focused on the firmware, as the communication with this sensor is different, but basically the same as with the MH-Z19B or MH-Z19C sensors.
