First Alert Carbon Monoxide Alarm - tear-down | MyThinkPond

One of my First Alert Carbon Monoxide Alarm’s expired. This gave me an opportunity to look inside and see what’s inside this little gadget.

Here is a picture of the tear-down for those who are interested:

First Alert - Single Station Carbon Monoxide Alarm - model #: CO614




The specification for the carbon-monoxide sensor used in this model can be found here.

Here is a list of alternative carbon-monoxide sensors from Figaro.

Here is an alternative available at SparkFun. (Air Quality MQ135 sensor).
