LM35 Temperature Sensor

Description: This is a linear analog centigrade temperature sensor. These can be easily connect to one of the Arduino's analog pins to read temperatures.

Here is a technique from the Arduino Playground showing how to use the LM35 for high resolution temperature readings.

Features:

• TO-92 package
• Linear + 10.0 mV/˚C scale factor
• 0.5˚C accuracy
• Operates from 4 to 30 volts
