ESP32 Weather Monitoring System Using DHT11 Sensor and LCD Display

In this project, I build Weather Monitoring System using ESP32 & DHT11 Sensor. The DHT11 Sensor measures the temperature and humidity of the surrounding environment.

The measured values are displayed in real time on a 16*2 LCD Display.

LCD - ESP32

VCC - 5V

GND - GND

SDA - GPIO 14

SCL - GPIO 13

DHT11 - ESP32

+ - GND

Out - GPIO4

_ - 3V3

Install Required Libraries:

1. DHT11 Sensor Library (Adafruit)
2. Adafruit Unified Sensor
3. LiquidCrystal_I2C

Here I uploaded the video of Output.

1. The DHT11 Sensor measures temperature and humidity from the surrounding environment
2. Then sends this data to the ESP32 through its data pin.
3. The ESP32 processes the sensor reading using the DHT library.
4. After reading the value, it displays the temperature and room status on the LCD display.
5. This process repeats continuously, allowing real-time monitoring of environmental conditions.

This project demonstrates how to interface ESP32 with a DHT11 sensor and LCD display to create a simple weather monitoring system.
