How to measure room temperature using LM35 sensor with Arduino UNO

#temperaturesensor #lm35 #tempsensor
Science gully brings you a very simple and easy explanation of using LM35 temperature sensor for measurement of room temperature. You will get to know about different types of temperature sensors. How to connect LM35 to arduino UNO r3 and understand the concept of analog to digital as well as sensitivity of LM35. It also explains arduino program in a very easy way. A step by step explanation of program will help you understand the code and its application for temperature measurement.

Buy all the materials required for this experiments:

Program code :-
int val;
int tempPin = A0;

void setup()
{
}
void loop()
{
val = analogRead(tempPin);
float mv = ( val/1024.0)*5000;
float cel = mv/10;

delay(10000);

}

Even with the proper connections its showing around 50°C why so pls reply

Proper room temperature is not shown to us otherwise it shows"Your room temperature is 50.24°c" it is always exceed of 50°c not have shown less than 50°c
