Method Detail

setSignalDetectedThreshold

void setSignalDetectedThreshold(double threshold)

Set the minimum threshold for a signal to be considered detected

Parameters:

threshold - minimum threshold

getSignalDetectedThreshold

double getSignalDetectedThreshold()

Get the minimum threshold for a signal to be considered detected

Returns:

threshold

setMode

void setMode(IrSeekerSensor.Mode mode)

Set the device mode

Parameters:

mode - sample rate

getMode

IrSeekerSensor.Mode getMode()

Get the device mode

Returns:

device mode

signalDetected

boolean signalDetected()

Returns true if an IR signal is detected

Returns:

true if signal is detected; otherwise false

getAngle

double getAngle()

Estimated angle in which the signal is coming from

If the signal is estimated to be directly ahead, 0 will be returned. If the signal is to the left a negative angle will be returned. If the signal is to the right a positive angle will be returned. If no signal is detected, a 0 will be returned.

NOTE: not all sensors give an accurate angle.

Returns:

angle to IR signal

getStrength

double getStrength()

IR Signal strength

Detected IR signal strength, on a scale of 0.0 to 1.0, where 0 is no signal detected and 1 is max IR signal detected.

Returns:

signal strength, scaled from 0 to 1

getIndividualSensors

IrSeekerSensor.IrSeekerIndividualSensor[] getIndividualSensors()

Get a list of all IR sensors attached to this seeker. The list will include the angle at which the sensor is mounted, and the signal strength.

Returns:

array of IrSensors

setI2cAddress

void setI2cAddress(I2cAddr newAddress)

Set the I2C address to a new value.

getI2cAddress

I2cAddr getI2cAddress()

Get the current I2C Address of this object. Not necessarily the same as the I2C address of the actual device. Return the current I2C address.

Returns:

current I2C address
