This sensor 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 op-amp to amplify the signal to a more manageable volt-level.
This UV inspection sensor module is designed for high-reliability and accurate measurement of the ultraviolet index (UVI). It's suitable for measuring total sunlight UV intensity and complies with the World Health Organization's UV Index Classification Standard. The module detects UV wavelengths in the range of 200-370nm and offers a very fast response time with full interchangeability.
