This will be the last post on the subject of interfacing the First Alert CO Detector with a wireless ESP8266 module. The limits of the ESP8266 and lower costs of the higher functioning ESP32 module prove that this effort is not worth continuing. I will say that the overall simplicity of this project should provide a firm footing for future projects. The process from start to finish can be applied to any number of electronic devices. So with that said,…
“No changes are permanent, but change is” – Neil Peart Rush, Tom Sawyer It’s been quite sometime since my last post, my apologizes. I won’t be diving right back into the CO Detector project just yet. First, I’d like to cover some developments that have occurred the past two months. Late in April, there were updates available to my WordPress site. Updates are a constant flow and this was just another routine bit of work for maintaining the site. The…
In this post, I’ll be begining to cover the Arduino code used to program the ESP8266, as it pertains to the CO Detector. Most of what I’ll be going over here is based off of Rui and Sara Santos’s work at https://randomnerdtutorials.com/about/. They have done a tremendous amount of work and deserve the attention for it. The ESP8266 will be replacing the ins and outs to the CO Detector. Besides the typical operation of the CO Detector, we’ll need to…
