CO2 Sensor component not described

Post by everseeker »

OK, I am not as comfortable as I once was around a soldering Iron, but I was asked(Pestered) by my wife to build/bash/make a CO2 Sensor...
So, came here and found this : https://www.adafruit.com/product/4867?g ... hYQAvD_BwE

Looks perfect, I want to order one... But holdonasec... It seems to be the case that ONLY the sensor is the item for sale. Not a problem... But WHAT is the other part (The readout)
I would like that too, to complete the product as shown, but I can't figure out WHAT it is/What to buy

Help?

There are actually two things here:

The display that you see in the photo is this FeatherWing:
https://www.adafruit.com/product/4650

The second item, which is sitting underneath the display, would be a Feather main board. Not sure which exact one is used in the product demo, but there are lots of choices. This is what is actually running the code that is talking to the sensor and updating the display.

This guide has a good overview of what Feather (main boards) and FeatherWings (accessory add boards) are:

Thank you very much. I WISH I had seen this before this morning... You had a sale on Feathers... Oh Well.
So, a valid parts list might be:

Assembled Feather HUZZAH w/ ESP8266 WiFi With Stacking Headers
Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor - STEMMA QT / Qwiic PID: 4867
Adafruit FeatherWing OLED - 128x64 OLED Add-on For Feather - STEMMA QT / Qwiic PID: 4650

Correct?

That looks generally correct. The one other item would be the little cable between the TFT and the SCD30. That's one of these:
https://www.adafruit.com/product/4210

Note the cable comes in various lengths. Linking to 100mm, as that appears to be what is shown in photo. But you could use a different length if you wanted.

EDIT - just to mention, an ESP8266 based board would be Arduino only. If you wanted to use CircuitPython, checkout the various Feather options here:
