Uv light sensor guva-s12sd module

Uv light sensor guva-s12sd module


Uv light sensor guva-s12sd module.

Extend your light-sensing spectrum with this analog uv sensor module. 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..
