Stay prepared with the most reliable smoke detectors for fire and carbon monoxide detection -- tested and recommended by our ...

It’s widely known that a smoke detector is a good ionizing radiation source, as they contain a small amount of americium-241, a side product of nuclear reactors. But what about other sources?

There are two different types of smoke alarms—single-sensor ionization and single-sensor photoelectric units. They work differently in order to detect smoke. Ionization detectors use a very ...

He is in charge of developing and carrying out testing procedures for a wide variety of home appliances and smart devices including robot vacuums, smoke/CO detectors and air conditioning units.

Smoke alarms, or at least ionization-based alarms with a tiny amount of radioactive americium, are very simple devices. Inside the alarm, there’s a metal can – an ionization chamber – with ...

All smoke detectors use one of two types of sensors to detect fires. Ionization-type sensors are best at detecting fast-burning fires, while photoelectric sensors are generally better at alerting ...

Ionization smoke alarms use a battery and two metal plates, called electrodes, to create an electrical circuit. Ions are tiny, electrically charged particles that flow through the circuit and ...

The best smoke detector can provide an important first line of defense from fire. We recently put the top smoke detectors to the test. See which ones performed best.

Ring and Kidde have partnered up for CES 2025 and a new set of smoke detectors that will be smarter than ever thanks to Ring compatibility. Kidde already dominates our list of the best smoke ...
