LM35 Temperature Sensor IC’s

temperature

LM35  is a temperature sensor integrated circuit  ( I C ) whose output is directly proportional to the rise in temperature (C ) . This I C is not subjected to any oxidation because of sealed circuit of LM35 I C . This LM35 I C is much more efficient than thermistor so we use this LM35 Integrated Circuit as it can measure the temperature accurately . This Integrated Circuit can attain the heat of upto 0.1 oC maximum that is it is low self heated .

Its operating temperature ranges from -55 oC to 150 oC  . Its scale factor is 0.01 V/oC that is the output voltage varies by 10 mV with every one oC rise or fall in temperature .

It consists of three pins GND ( Ground ) , Vcc , OUT .
