The application prospect of ultraviolet flame sensor will be broader
Human five sense organs are very complex and sensitive "sensors", but most people's five sense organs can only "qualitatively" perceive external information, not quantitative perceiving, and there are many physical quantities that human five senses cannot perceive. For example, they can perceive visible light for vision, but they cannot perceive the invisible spectrum with a wider frequency domain. These invisible lights can be sensed by infrared and ultraviolet flame sensors.

The flame sensor is a sensor specially used by the robot to search for the source of fire
The flame is composed of various combustion products, intermediates, high-temperature gases, hydrocarbons and inorganic substances as the main high-temperature solid particles. Flame heat radiation includes discrete spectrum gas radiation and continuous spectrum solid radiation. The flame radiation intensity and wavelength distribution of different combustion products are different.

Flame sensor, also known as photosensitive fire detector, has a wide range of applications
The automatic fire alarm system is an important part of daily life and industrial safety monitoring system, and it is an important means to ensure safe operation and reduce casualties and property losses when a fire occurs.

Flame sensor function
The flame detector is a kind of fire detector used to detect the light intensity of the flame burning and the flicker frequency of the flame, also known as the photosensitive fire detector. At present, flame detectors can be divided into ultraviolet detectors that are sensitive to ultraviolet rays with a shorter wavelength in the flame, infrared detectors that are sensitive to infrared radiation with a longer wavelength in the flame, and simultaneously detect ultraviolet rays with a shorter wavelength and a shorter wavelength in the flame. Long infrared UV/IR hybrid detector. According to the detection band, the flame detector can be divided into single ultraviolet, single infrared, dual infrared, triple infrared, infrared ultraviolet and additional video; according to the type of explosion-proof, it can be divided into:

Beautiful and colorful glass lamp housing is not only suitable for home use but also suitable for commercial use
Chandeliers are used in living rooms, dining rooms, etc., and the decorative effect is also very good. Many people also like to add a layer of lamp shells outside the chandelier. What material is the shade of the chandelier? Not only the chandeliers need lamp shells, but table lamps also need lamp shells, but many people don’t know what material is good for table lamp lamp shells.

How to choose the right glass lamp housing? What should I do if the glass lamp housing turns yellow?
Glass lamps are also an early product of thermoplastics. They have the advantages of long-lasting color, good transparency, good chemical stability, and good abrasion resistance. Therefore, glass lamps are very common in homes. The glass lampshade will age after being used for a long time. One of the phenomena of aging is that the inside of the lamp housing turns yellow.
