MLX90614 IR Thermometer Hookup Guide -

Getting values out of the sensor is a two-step process: read from the sensor then get the updated values. To read from the sensor, call the read() function, which will return 1 on success (or 0 if it fails). If the read() function succeeds, you can grab the updated ambient and object temperatures using the ambient() and object() functions:
