So that’s all info you need about LM35 for this particular temperature display project using Arduino UNO. Lets get to LM35 temperature sensor interfacing with Arduino. It can measur… To copy the code, click on the button in the top right corner of the code field. So lets get to building the Arduino Temperature Sensor. You can upload the example code to your Arduino using the Arduino IDE. LM35 is three terminal linear temperature sensor from National semiconductors. Once we successfully interface arduino and lm35, we will go on to build a temperature display using arduino and a 16×2 LCD module which constantly monitors temperature around the measurement field/range of LM35 and displays the same on LCD module. LM35 PINOUT. With the following example code, you can read the temperature from an LM35 sensor and display it in the Serial Monitor. Arduino Temperature Sensor Using LM35: IntroductionThe LM35 series are precision integrated-circuit temperature devices with an output voltage linearly proportional to the Centigrade temperature. LM35 analog temperature sensor with Arduino example code.
