Constructor Detail

LuxSensor

public LuxSensor()
          throws java.io.IOException,
                 com.pi4j.io.i2c.I2CFactory.UnsupportedBusNumberException,
                 java.lang.InterruptedException

Throws:

java.io.IOException

com.pi4j.io.i2c.I2CFactory.UnsupportedBusNumberException

java.lang.InterruptedException

LuxSensor

public LuxSensor(byte addr)
          throws java.io.IOException,
                 com.pi4j.io.i2c.I2CFactory.UnsupportedBusNumberException,
                 java.lang.InterruptedException

Parameters:

addr - I2C hardware address of the device. For us that's 0x39

Throws:

java.io.IOException - If there is a hardware I/O error

com.pi4j.io.i2c.I2CFactory.UnsupportedBusNumberException - If bus number is invalid

java.lang.InterruptedException - If thread fails to sleep.

Method Detail

getReading

public double getReading()
                  throws java.io.IOException,
                         java.lang.InterruptedException

Returns:

Reading as a double (unitless)

Throws:

java.io.IOException - if device isn't ready for I/O

java.lang.InterruptedException - Can happen during thread sleep
