After connecting the circuit, now upload the below code to your Arduino board.

And the last pin is connected to the GND pin of the Arduino board.This pin of Arduino board is used to receive analog data from an external source.Since LM35 generates an analog value at its output pin that's why I have connected this pin to the 'A0' pin of the Arduino board.The VCC pin of LM35 is connected to +5V of the Arduino board.As you can see in the above image, I have connected an LM35 sensor with Arduino UNO.I have connected LM35 with Arduino microcontroller and it is shown in the image given below:.As my today's tutorial is about interfacing LM35 with Arduino so let's start it.

The third pin is GND and should be connected to the ground of the battery/source.

The center pin is its Data Pin and LM35 gives its output when it measures temperature.

The first pin is Vcc, so it should be connected to 5V.

As you can see in the above image that LM35 is a 3 pin IC:.

The physical appearance of LM35 is shown in the image given below:

LM35 is a 3 pin IC and it is used for temperature detection.

The internal circuitry of this embedded sensor is sealed inside a capsule.

Lm35 is much more sensitive than other temp measuring devices (not accurate).

Its output is generated in the form of an Electrical signal and this electrical signal is proportional to the temperature, which it detects.

LM35 is an embedded sensor, used to measure the temperature of its surroundings and is famous because of its low cost.

First of all, let's have a quick look at the introduction of LM35 and then we will design it in Proteus ISIS. Now, let's move towards its interfacing and its practical applications. And as it's cheap, that's why it's not very reliable, if you personally ask me then I will prefer DS18B20 over LM35 because of its accurate readings. Because learning new things is always a charm.Īn excellent thing about LM35 is that it's quite cheap as compared to other temperature sensors. So I thought I should also upload its tutorial as it will also be advantageous for engineering students. Then, I get to know much about LM35, its operating conditions and features. Recently I got a chance to work on a project regarding temperature sensing but the condition of this project was that to use only LM35 for temperature detection. So far, I have only worked on temperature sensor DS18B20 for temperature measurements and I have also uploaded a tutorial on Interfacing of Temperature Sensor 18B20 with Arduino. Today I am going to share a new project titled Interfacing of temperature sensor LM35 with Arduino UNO in Proteus ISIS. Hello friends, I hope you all are fine and enjoying yourself.
