Carbon monoxide detector

A carbon monoxide detector is a small machine that can help keep you safe from something called "carbon monoxide," which is a gas that you can't see, smell, or taste.

When things like wood, gasoline, or natural gas are burned, they can release this gas. If you breathe in too much of it, it can make you very sick or even cause you to die. So, the carbon monoxide detector helps keep you safe by sensing when there is too much of this gas in the air and making a loud noise to let you know to get out of the area.

It's kind of like having a superhero by your side, watching out for you all the time, so you can stay safe and healthy!
