Uva And Uvb Light Sensor
One that is primarily sensitive in the uva spectral range and one that is sensitive in the uvb spectral range.
Uva and uvb light sensor. The device is connected via an i2c interface to a microcontroller. Uv exposure that leads to sunburn has proven to play a strong role in developing melanoma the most dangerous of the three most common types of skin. Solar light s model pma1110 analog uva sensor provides fast and accurate irradiance measurement in the uva region with spectral response in the 320nm to 400nm range. It uses a uv photodiode which can detect the 240 370nm range of light which covers uvb and most of uva spectrum.
The signal level from the photodiode is very small in the nano ampere level so we tossed on an opamp to amplify the signal to a more manageable volt level. The veml6075 from vishay has both true uva and uvb band light sensors and an i2c controlled adc that will take readings and integrate them. This sensor is ideal for laboratory applications measuring mercury xenon metal halide or fluorescent lamps commonly used for uva studies as well as sunlight. When the uv sensor is applied it is able to detect uva and uvb intensity to provide a measure of the signal strength as well as allowing for uvi measurement.
Uvb 280 to 315 nm and uva 315 to 400 nm are the most relevant spectral ranges in the solar uv spectrum. Extend your light sensing spectrum with this analog uv sensor module. When the uv sensor is applied it is able to detect uva and uvb intensity to provide a measure of the signal strength as well as allowing for uvi measurement. The veml6075 senses uva and uvb light and incorporates photodiode amplifiers and analog digital circuits into a single chip using a cmos process.
Other i2c or smbus devices can be connected to the same interface. The veml6075 senses uva and uvb light and incorporates photodiode amplifiers and analog digital circuits into a single chip using a cmos process. Adafruit industries unique fun diy electronics and kits adafruit veml6075 uva uvb and uv index sensor breakout id. Although both uvb and uva are carcinogenic and contribute to skin aging uvb is 1000 times more erythrogenic with distinct biological effects to the skin compared to uva irradiation and uvc is on an order of magnitude more intense than uva causing nearly instant biological effects to.
The pma1107 analog uva uvb sensor gives an accurate measurement of non weighted uvb uva ultraviolet radiation from sunlight or artificial light sources. When the uv sensor is applied it is able to detect uva and uvb intensity to provide a measure of the signal strength as well as allowing. Uva and uvb light sensor with i2c interface description the veml6075 senses uva and uvb light and incorporates photodiode amplifiers and analog digital circuits into a single chip using a cmos process.
