Fire Detectors – UV Flame Detectors – Fire Safety Tips

The most significant benefit of having IR and UV sensors combined in a single unit or device is that they share the same alarm source. As previously mentioned, each device operated separately, but adding a signal processing algorithm will enable the combination of both sensors to deliver an outstanding fire detector performance to a wide range of volatile solids, gases, and flammable liquids ...

Fire Detector using Flame Sensor and Arduino Interface

· The project fire alarm or fire detector using Flame sensor and Arduino board is a wonderful project. The sensor basically detects IR (Infra-Red) light wavelength between 760 nm – 1100 nm (nanometer) that is emitted from the fire flame. Most of the flame sensors came with the YG1006 sensor which is a high speed and high sensitive NPN silicon phototransistor. You can check this …
