Display Temperature and Humidity on LCD

Display Temperature and Humidity on 16x2 LCD

Things used in this project

Hardware components

Arduino UNO

DHT11 Temperature & Humidity Sensor (3 pins)

Rotary potentiometer (generic)

I used a bigger potentiometer but don't worry this potentiometer will work even better. 10k pot will be perfect but you can use any other for sure

Breadboard (generic)

Jumper wires (generic)

Software apps and online services

Arduino IDE

Story

I put some effort in this because watching a million of tutorials was really a nightmare. Here is every tutorial and everyhting you need to know about how to display Temperature and Humidity via LCD Display 16x2.

1. Go to Arduino IDE, then go to Arduino Library and Search for DHT11. Download the library.

2. Do the same with LCD display, and download the LuqidCrystal.

I think every ArduinoIDE has LuqidCrystal already downloaded but if they don't have you have to download them as I described.

3. Let's do the hardware first :

- You need to connect DHT11 sensor on Arduino Uno.

DHT11 Arduino Uno

GND GND

VCC 5V

DATA D6

- Potentiometer

Left pin to Ground

Right pin to 5V

Middle pin to V0 of LCD Display

//You can switch rigjt and left pin it will work the same

- Then connect LCD display to Arduino

LCD -----Arduino Uno

VSS------Ground

VCC------5V

V0-------Potentiometer middle pin

RS-------D12

RW------GND

E--------D11

D4------D5

D5------D4

D6------D3

D7------D2

A -------5V

K -------GND

Code

Temp Hum LCD

#include <LiquidCrystal.h>
#include <DHT.h>
int pin = 6;
int type = DHT11;
DHT dht (pin, type);
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {
  // put your setup code here, to run once:
  lcd.begin(16, 2);
   dht.begin();
}

void loop() {
  // put your main code here, to run repeatedly:
 
 
 float Temp = dht.readTemperature();
  lcd.setCursor(0, 0);
   lcd.print("Temp:");
    lcd.print(Temp);
     lcd.print("C");

 float Humid = dht.readHumidity();

  lcd.setCursor(0, 2);
   lcd.print("Humid:");
    lcd.print(Humid);
     lcd.print("%");

}
