Introduction

The LM35 series square measure exactness integrated-circuit temperature devices with associate degree output voltage linearly proportional to the Centigrade temperature. LM35 is a 3 terminal linear temperature detector from National Semiconductors. It will live temperature from -55 degree Centigrade to +150 degree Centigrade. The voltage output of the LM35 will increase 10mV per degree Centigrade rise in temperature. LM35 will be operated from a 5V offer and also the stand by current is a smaller amount than 60uA. The pinout of LM35 is shown within the figure below.
