Temperature and Humidity Sensor

Building an temperature and humidity sensore

1- Breadboard. https://a.co/d/5JgXTQz

2- Jumper wires. https://a.co/d/1GdRblX

3- Dht11 sensor. https://a.co/d/iQ7q5OJ

4- Ardunio uno. https://a.co/d/44aqo58

5- Lcd. https://a.co/d/7TuVVJF

6- 10k Potentiometer. https://a.co/d/55CEDLb

This is the circuit diagram

The code .

take this code and paste it in ardunio ide

#include <DHT.h>

#include <LiquidCrystal.h>

// Set DHT pin

#define DHTPIN 2

// Initialize LCD with the interface pins (RS, E, D4, D5, D6, D7)

LiquidCrystal lcd(7, 8, 9, 10, 11, 12);

// Define DHT sensor type

#define DHTTYPE DHT11

DHT dht(DHTPIN, DHTTYPE);

void setup() {

// Setup LCD's number of columns and rows

lcd.begin(16, 2);

dht.begin();

// Print a message to LCD

lcd.print("Temp: Humidity:");

}

void loop() {

delay(2000); // changed this to 2 seconds between readings

// Read humidity

float h = dht.readHumidity();

// Read temperature in Fahrenheit

float f = dht.readTemperature(true);

// Check if any reading failed

if (isnan(h) || isnan(f)) {

lcd.setCursor(0, 1); // Move cursor to the second row

lcd.print(" Sensor Error ");

return; // Skip the rest of the loop if there's an error

}

// Display temperature and humidity on the LCD

lcd.setCursor(0, 1);

lcd.print("T: ");

lcd.print(f, 1); // Display temperature with 1 decimal place

lcd.print("F ");

lcd.print("H: ");

lcd.print(h, 1); // Display humidity with 1 decimal place

lcd.print("%");

}

Don't forget to install the two libraries for the lcd and dht11

After this run the code and you had finished your project
