Ultraviolet sensor used in clothing ultraviolet disinfection cabinet

"Spring rains are lingering, Qingming rains, rains keep raining, and heavy rains in summer" will soon usher in a new wave of precipitation, and clothing will not see the sun-continue to "dry in the shade" slowly. In the rainy season, washing clothes is definitely the most worrying thing, because the clothes are not sun-dried and difficult to dry.
Microbiological studies have shown that there is an average of 0.1g of feces on a pair of dirty underwear, which contains tens of thousands or even tens of millions of bacteria. It is impossible to completely wash off these bacteria after three or five times of water. If the underwear after washing is not exposed to dry in time, it will become a petri dish for bacteria. The growth rate of bacteria is very fast, it can reproduce one generation every 20 minutes or so. If you only have 1 bacteria left on the underwear you just washed, it will be 8 after 1 hour in a humid environment, 64 after 2 hours, and 512 in 3 hours. One, 4096 in 4 hours, hundreds of millions of bacteria will multiply after underwear is dried in the shade for a week.

Don't be afraid, you can use an ultraviolet disinfection cabinet to sterilize your clothes. Where there are usually ultraviolet germicidal lamps, the air is particularly fresh. That's because ultraviolet rays can purify the air, eliminate musty odors, and produce a certain amount of negative oxygen ions, which is beneficial to human health.
Cells have a pattern in the absorption spectrum of light waves, with the maximum absorption of ultraviolet rays between 250 and 270 nm. These absorbed ultraviolet rays act on the genetic material of the cell, namely DNA, which can play a kind of actinic effect. The energy of ultraviolet photons can destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in microbial cells, causing growth cell death and (or) regenerative cell death, achieving the effect of sterilization and disinfection.
The principle of ultraviolet disinfection cabinet:
ultraviolet rays can only travel in a straight line, with low radiation energy and weak penetrating power, and can only kill directly irradiated microorganisms. Therefore, when disinfecting, try to expose the disinfected parts to ultraviolet rays. Ultraviolet light is a short wave with a wavelength outside the visible range. It is a kind of visible "blue light" produced according to the principle of radiology and does not have a disinfection effect. Ultraviolet rays can be divided into A, B, and C according to the wavelength range.
Among them, C-wave ultraviolet rays have the real bactericidal effect, especially the ultraviolet rays with a wavelength of 253.7nm. Ultraviolet rays can kill various microorganisms, including bacterial propagules, spores, mycobacteria, viruses, fungi, rickettsiae and mycoplasma, etc., with a broad spectrum.
The principle of sterilization is to use ultraviolet rays to irradiate bacteria, viruses and other microorganisms to destroy the structure of DNA (deoxyribonucleic acid) in the body, causing it to die immediately or lose its ability to reproduce. The disadvantage is that ultraviolet rays can only travel in a straight line, the radiation energy is low, and the penetrating power is weak. It can only kill the directly irradiated microorganisms. Therefore, the disinfected parts should be fully exposed to ultraviolet rays when disinfecting.
The working principle of the ultraviolet disinfection cabinet:
through the cycle of ultraviolet radiation and ozone, it penetrates the cell membrane of microorganisms, destroys the DNA structure of various germs, bacteria, parasites and other pathogens, destroys their nucleic acid molecular bonds, and causes the bacteria to die or die immediately. Can not reproduce offspring, so as to achieve the effect of disinfection and sterilization. Destroy and change the DNA (deoxyribonucleic acid) structure of microorganisms to achieve the purpose of sterilization.
1. Double ultraviolet and ozone low-temperature cycle disinfection (≤50℃)
2. Strong penetration, thorough disinfection, every corner can be disinfected, no dead ends, no residues.
3. Special sealing material, no ozone leakage when the disinfection cabinet works, and the effect is good.

Finally, the editor of Gongcai.com recommends an ultraviolet sensor used in the ultraviolet disinfection cabinet. The high-quality ultraviolet sensor imported from abroad by Gongcai.com-GUVC-S10GD, GUVC-S10GD mainly detects the wavelength range of 254nm. The sensor is packaged in a smd3535 metal outer (Al) shell. The area of ​​the photosensitive chip is 0.076mm². The output of the ultraviolet sensor is mainly related to the responsivity, the photosensitive area of ​​the sensor and the light intensity. The ultraviolet sensor is suitable for use in some disinfection equipment or products with strict requirements on product volume.
