Problems solved by technology

[0002] The currently widely used flame detectors include temperature detectors (glass balls or hot-melt metals), smoke detectors and point-type flame detectors. Smaller occasions; point-type flame detectors are generally suitable for tall spaces and dusty environments. There are two types of infrared flame detectors and ultraviolet flame detectors, and there are obvious shortcomings at the same time: weak anti-interference ability Setting or grading selection, flame detectors are usually installed on the top of the building space, the sensitivity of the detector is preset before installation, after installation and put into use, it often occurs when the application environment changes or the preset detector sensitivity is not suitable , it is difficult for people to approach the detector to adjust its detection sensitivity, which is likely to cause false alarms
