How Do Smoke and Carbon Monoxide Detectors Work?

Everyone is well-aware of how imperative it is to keep working smoke alarms in your home, but many are unaware of how these devices actually detect the smoke and carbon monoxide that they come into contact with. The most common form of smoke detectors are called photoelectric detectors, and they sense smoke in the surrounding area by sending off laser beams of light which can automatically identify traces of smoke. Carbon monoxide detectors are often biomimetic, which means that they include a gel that changes in hue when in contact with carbon monoxide, sending a signal to set the alarm off.

Key Takeaways:

  • Many smoke detectors work by sensing the presence of smoke through laser beams that they send throughout the room.
  • Carbon monoxide detectors often contain a gel that changes in color when it comes into contact with the dangerous substance.
  • It is imperative that all of your monitors are working correctly in order to protect you and your loved ones.

“The smoke detectors that provide critical fire warnings and the carbon monoxide detectors that protect you from an invisible threat are extremely basic, and that’s part of what makes them so reliable, compact and inexpensive.”
