Tear-Down, Technology

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:

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).

The second picture can be zoomed in by opening the image on a separate window.
