You should fully test your device before installing it in your home.
You can add any sensor that you like and turn of any device you like.
I advice to use a quality sensor, that you know for sure will detect Carbon monoxide.
My device is just a prototype to show you how to build it.
I used the MQ9 sensor ordered from china.
