Setup function is pretty simple as well. sensors.begin() initializes the sensor. With sensors.setResolution(address, resolution) we can change the resolution of a sensor. The sensor can output values in 9, 10, 11 or 12 bits. Lower resolution means faster measurements:
9 bits: increments of 0.5C, 93.75ms to measure temperature;
10 bits: increments of 0.25C, 187.5ms to measure temperature;
11 bits: increments of 0.125C, 375ms to measure temperature;
12 bits: increments of 0.0625C, 750ms to measure temperature.
