LM35 Temperature Sensor

LM35 is an analog temperature sensor device which outputs voltage proportional to Degree Centigrade. It does not require any external timing signal or calibration for accurate results. Because of linear output
And low output impedance it can be interfaced with variety of control circuitry. No extra components required to interface LM35 to an ADC because of linear out of LM35 which is 10mv/degree scale. It can be directly connected to any 10- or 12-bit ADC.

LM35 can also be directly interfaced to Arduino and other microcontrollers
