Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`float`	`getHigh()`	The highest raw light value this sensor can return from intense bright light.
`float`	`getLightValue()`	Returns the calibrated and normalized brightness of the white light detected.
`float`	`getLow()`	The lowest raw light value this sensor can return in pitch black darkness.
`float`	`getNormalizedLightValue()`	Returns the normalized value of the brightness of the white light detected, such that the lowest value is darkness and the highest value is intense bright light.

- Method Detail
  - getLightValue
```
float getLightValue()
```
    Returns the calibrated and normalized brightness of the white light detected.
    
    Returns:
    
    A brightness value between 0 and 100%, with 0 = darkness and 100 = intense sunlight
  - getNormalizedLightValue
```
float getNormalizedLightValue()
```
    Returns the normalized value of the brightness of the white light detected, such that the lowest value is darkness and the highest value is intense bright light.
    
    Returns:
    
    A raw value, between getLow() and getHigh(). Usually between 0 and 1.00 but can be anything depending on hardware. low values = dark, high values = bright
  - getHigh
```
float getHigh()
```
    The highest raw light value this sensor can return from intense bright light.
    
    Returns:
    
    the high value
  - getLow
```
float getLow()
```
    The lowest raw light value this sensor can return in pitch black darkness.
    
    Returns:
    
    the low value
