Aluminum UV sensor view
The circuit of our UV sensor integrates imported U.S.-made industrial-grade microprocessor chips and high-precision ultraviolet sensing components, ensuring exceptional product reliability and measurement accuracy. Two housing options are available: a wall-mounted high-protection enclosure and an aluminum alloy housing, both of which effectively protect against rain, snow, and other harsh outdoor elements. For outdoor applications, we recommend the aluminum housing version. This UV sensor can be integrated with wind speed sensors, wind direction sensors, solar radiation sensors, rain gauges, solar radiation shields, light sensors, rain/snow sensors, soil sensors, and other devices to form a complete weather station monitoring system.
Aluminum UV sensor features
- 1. The UV measurement range is 290 to 390 nm, covering the solar UV range and the UV output range of electric lamps.
2. Based on the principle that photosensitive elements convert UV rays into measurable electrical signals, online monitoring of UV rays is achieved.
3. Fully enclosed aluminum shell, protection level IP67.
4. Our UV sensor widely used in environmental monitoring, meteorological monitoring, agriculture, forestry and other environments. Measure UV rays in the atmosphere and in environments such as artificial light sources.

Calculation method
1. Current output signal conversion calculation
Ultraviolet intensity range 0-15 mW/cm2, 4~20mA output, when the output signal is 12mA, calculate the current ultraviolet intensity value. The span of this ultraviolet intensity range is 15 mW/cm2, expressed by 16mA current signal, 15/16=0.9375, that is, the current 1mA represents the ultraviolet intensity change of 0.9375 mW/cm2, the measured value is 12mA-4mA=8mA, 8*0.9375=7.5 mW/cm2, and the current ultraviolet intensity is 7.5 mW/cm2.
2. Voltage output signal conversion calculation
Ultraviolet intensity range 0-15 mW/cm2, 0-10V output, when the output signal is 5V, calculate the current ultraviolet intensity value. The span of the UV intensity range is 0-15 mW/cm2, expressed by a 10V voltage signal, 15/10=1.5, that is, a voltage of 1V represents a change of 1.5 mW/cm2 in UV intensity, and the measured value is 5V-0V=5V, 5*1.5 =7.5 mW/cm2, and the current UV intensity is 7.5 mW/cm2.

UV sensor FAQs
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.
When used in a normal environment, our company provides a two-year warranty.
