Ocean: Si1145 Ultraviolet Sensor for Raspberry Pi and Arduino.

This is a multi-functional optical measurement function module that mainly measures ultraviolet rays. The module has an onboard Si1145 sensor chip that can directly output an integer of 100 times the ultraviolet index. Users can obtain the ultraviolet index value without data conversion and calibration. The module also supports the measurement of ambient light intensity, including infrared intensity and visible light intensity.

NOTE: The output voltage of the UV sensor increases with the enhancement of the ultraviolet intensity. and the maximum output voltage of UV sensor is 2V to 3V. When the ultraviolet intensity is not strong, the output voltage may be in the range of 0.01-0.1V. It's recommended to test the module outdoor or irradiate the module with UV LED.
