support for mega2560 ?

Partially.

The CoreSensors library offers voltage and temperature measurement. The ATmega2560 supports voltage measurement, but not temperature.

According to the datasheet (figure 26-1 on page 269) the ATmega2560 offers a second internal voltage reference instead of i.e. the ATmega328's thermal diode. So the ATmega2560 unfortunately lacks the hardware required to measure internal temperature (a featured in this library).
