To get started:
- use a simple NTC-Resistor
- create a voltage-divider with it
- connected it the an AD-Converter either the internal ADC if the
controller has one or use an external ADC with a digital interface like
SPI or I2C.

You may also check sensors with digital interface like i.e. the DS1820
(onewire), SHT75 (with humidity, special protocol), several with SPI
and/or I2C from ADI.
