Temperature Meter Using Arduino Uno

Thubnail Maker.png

Hello Friends welcome back to Techno-E-Solution, In this Video I'll show you how to make "Temperature Meter Using Arduino Uno", To measure the temperature of room I'm using LM35 temperature Sensor & LCD Display used to Display the temperature in fahrenheit & celsius. so for making this project I'm going to use LM35 Temperature sensor. Whose output voltage across the out pin is varies with respect to the temperature. I provide the complete details of the project like circuit diagram & Arduino code with demonstration Video.

Follow the circuit diagram for making connection. I make this circuit in Easy EDA software.

<<<<< Arduino + LM 35 >>>>>

5V ----- VCC

GND ----- GND

A0 ----- Vout

<<<<< Arduino + LCD Display >>>>>

5V ----- VCC

GND ----- GND

A4 ----- SDA

A5 ----- SCL

Simply Copy the following code & upload in your Arduino IDE software.

/*
 * Hello Friends Welcome To "Techno-E-Solution"
 * Here is the code for Arduino Temperature Meter...
 */
 
int t=0;
int sensor = A0;
float temp;
float tempc;
float tempf;
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27, 2, 16);
void setup() {
pinMode(sensor,INPUT);
lcd.init();
lcd.backlight();
lcd.setCursor (0,0);
lcd.print ("    ARDUINO     ");
lcd.setCursor (0,1);
lcd.print ("TEMPRETURE METER");
delay (3000);
Serial.begin(9600);
} void loop() {
delay(2000);
t=t+2;
temp=analogRead(sensor);
tempc=(temp*5)/10;
tempf=(tempc*1.8)+32;
Serial.println("_______");
Serial.println("Temperature Logger");
Serial.print("Time in Seconds= ");
Serial.println(t);
Serial.print("Temp in deg Celcius = ");
Serial.println(tempc);
Serial.print("Temp in deg Fahrenheit = ");
Serial.println(tempf);
lcd.setCursor(0,0);
lcd.print("Temp in C = ");
lcd.println(tempc);
lcd.setCursor(0,1);
lcd.print("Temp in F = ");
lcd.println(tempf);
}
