  • An Exceptionally Small UV Sensor | Hackaday

    hackaday.com 02 May '15, 8pm

    That’s cool the sensor manages a linear response compared to ideal despite not being sensitive over anything shorter than UV-A. The title is misleading in that they did not manufacture the UV sensor, it’s an off the shelf part. Nor can you, as the project blog states, measure UV index...
