Module description:
This module is based on the principle of a resistor divider design, enabling the terminal interface input voltage reduced five times, Arduino analog input voltage up to 5V, then the input voltage voltage detection module can not be greater than 5V × 5 = 25V (3.3V if used system, the input voltage can not be greater than 3.3Vx5 = 16.5V). Because Arduino AVR chips used in 10 AD, so the analog resolution of this module is 0.00489V (5V / 1023), so the minimum voltage detection module detects input voltage is 0.00489V × 5 = 0.02445V.

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.
