carbon monoxide detectors

Toxic fume sensors

Carbon monoxide detectors are devices that sound an alarm when they sense dangerous levels of carbon monoxide gas—an odorless, colorless byproduct of combustion that can be lethal.

Most building codes require them in homes with gas appliances or attached garages: The carbon monoxide detector started beeping at 3 a.m.
