LM35 Temperature Sensor is a precession Integrated circuit Temperature sensor, whose output voltage varies, based on the temperature around it. It is a small and cheap IC which can be used to measure temperature anywhere between -55C to 150C. It can easily be interfaced with any microcontroller that with ADC Capabilities or any development platform like Arduino.

Minimum and Maximum Input Voltage is 35V and -2V respectively. Typically 5V.
Can measure temperature ranging from -55C to 150C
Output voltage is directly proportional (Linear) to temperature (i.e.) there will be a rise of 10mV (0.01V) for every 1C rise in temperature.
0.5C Accuracy
Drain current is less than 60uA
Low cost temperature sensor
Small and hence suitable for remote applications
