LM35 Temperature Sensor

This is an Arduino Temperature Sensor based on LM35 temperature chip.

Features:

• Functional range: 0 degree Celsius to 100 degree Celsius
• Sensitivity: 10mV per degree Celsius
• Output voltage proportional to temperature

The LM35 chip, produced by National Semiconductor Corporation, is commonly used as a temperature measurement sensor. It includes thermocouples, platinum resistance, thermal resistance, and temperature semiconductor chips, commonly used in high-temperature measurement thermocouples.

Specifications:

• Temperature range: 0-200 degrees or below
• Good linearity and high sensitivity
• Calibrated directly in Degree Celsius
• Linear + 10.0 mV/˚C scale factor
• 0.5˚C accuracy guarantee-able (at +25˚C)
• Rated for full −55˚ to +150˚C range
• Operates from 4 to 30 volts
• Less than 60 µA current drain
• Low self-heating: 0.08˚C in still air

The LM35 linear temperature sensor, in combination with a sensor-specific expansion of Arduino board, can be very easy to achieve.
