Interface LightDetector

public interface LightDetector

A platform independent implementation for sensors that can detect white light levels.

Method Summary

Modifier and Type	Method and 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
