Method Detail

getLightDetected

double getLightDetected()

Get the amount of light detected by the sensor, scaled and cliped to a range which is a pragmatically useful sensitivity. Note that returned values INCREASE as the light energy INCREASES.

Returns:

amount of light, on a scale of 0.0 to 1.0

getRawLightDetected

double getRawLightDetected()

Returns a signal whose strength is proportional to the intensity of the light measured. Note that returned values INCREASE as the light energy INCREASES. The units in which this signal is returned are unspecified.

Returns:

a value proportional to the amount of light detected, in unspecified units

getRawLightDetectedMax

double getRawLightDetectedMax()

Returns the maximum value that can be returned by getRawLightDetected().

Returns:

the maximum value that can be returned by getRawLightDetected

enableLed

void enableLed(boolean enable)

Enable the LED light

Parameters:

enable - true to enable; false to disable

status

java.lang.String status()

Status of this sensor, in string form

Returns:

status
