From this table the formula is derived (spreadsheet) which is pretty linear between UV 1 and 11.

There is an extended library version which has more functionality and documentation.

### Notes
Note: The sensor is not calibrated and the table is indicative for sunlight (assumption!) and therefore not suitable for e.g. medical or industrial usage.

and therefore not suitable for e.g. medical or industrial usage.
Note: UV radiation will not go through glass, so inside you will most likely always read zero. This may help to calibrate the zero level of the sensor.

This may help to calibrate the zero level of the sensor.
Note: depending on the light source used, the table above is incorrect.
#### Sensitivity
### Sensitivity
The sensor is sensitive for wavelengths from 200 - 370 nm, so mostly in UVB and UVA region and less in the UVC.

### Future
## Future
Future development will be done in the library version only.
- https://github.com/RobTillaart/AnalogUVSensor
- verify vs calibrated sensor.
- investigate angle sensitivity (if the UV light comes from an angle).
- investigate response time to stabilize (e.g. does it react fast on clouds).
- investigate with different light sources (UVled, TL, sunlight).
- allow use of internal / external ADC.
- add a pin to control the power of the sensor (low energy applications).
