Smoke detector types Most household smoke detectors employ either an ionization or photoelectric (optical) sensor to detect a fire. Each uses a different method to sense the presence of smoke ...

What is the best smoke detector? Kidde's latest smoke detectors combine common-sense and extra-smart features. I simulated house fire smoke to ensure I picked only the most reliable option.

An indoor fire detection system might have optical sensors that look for smoke, thermal sensors that detect rising temperatures, and sensors for CO and CO 2 gas.

Given that smoke-producing flames are a constant fixture in these towns, Lumkani's Fire Detector senses the rate of the rise in temperature rather than smoke. That's supposed to lower the ...

Electronics and Telecommunications Research Institute (ETRI) announced the development of an AI sensor for unwanted alarm prevention that distinguishes between smoke caused by a fire and non-fire ...
