UV sensor FAQs
What is ultraviolet light?
Ultraviolet light refers to the wavelength of 10nm-400nm in the electromagnetic spectrum, which cannot be detected by the naked eye. Ultraviolet rays are divided into three categories: UVA, UVB, and UVC according to the band:
1. UVA has strong penetrability of long-wave ultraviolet rays, with a wavelength of 315 nm-400 nm. It can destroy elastic fibers and collagen fibers and can make the skin tan.
2. UVB is a medium-wave ultraviolet that has an erythema effect and can promote mineral metabolism and the formation of vitamin D in the body. The wavelength is 280 nm-320 nm, but long-term exposure is not recommended because it will suntan the skin and cause erythema peeling.
3. UVC is a short-wave ultraviolet light that has a sterilizing effect. The wavelength is 200 nm-280 nm. The UVC band is very harmful to the human body. Short-term exposure can burn the skin. If it is exposed for a long time, it will cause skin cancer.
Is this UV ray sensor waterproof?
When used in a normal environment, our company provides a two-year warranty.
How long is the warranty of this sensor?
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard.
Where to use ultraviolet rays sensor?
Ultraviolet rays sensors can be used in many different applications. For example, it is used in environmental monitoring, weather monitoring, agriculture, forestry, and other environments. Measure ultraviolet rays in the atmosphere and under artificial light sources. In addition, UV sensors are also used in the chemical industry for the production, storage, and transportation of chemicals.
The UV sensor is available in different appearances according to different places of use. For details, you can consult our professional technicians to provide you with the best solution.
