🚀 Arduino Weather Monitoring Project using DHT22 and OLED Display

I recently built a small Arduino-based weather monitoring system using a DHT22 temperature & humidity sensor and a 0.96" OLED display (SSD1306) with an Arduino Mega.

This project reads real-time environmental data and displays it clearly on the OLED screen. It also calculates additional values such as Heat Index and Dew Point, and visualizes the data with a live graph on the display.

🔧 Technologies & Components Used

• Arduino Mega 2560

• DHT22 Temperature & Humidity Sensor

• SSD1306 128x64 OLED Display (I2C)

• Arduino IDE & C++

• Adafruit SSD1306 / GFX Libraries

📊 Project Features

✔ Real-time temperature monitoring

✔ Humidity measurement

✔ Heat index calculation

✔ Dew point calculation

✔ Live graph visualization on OLED

This project helped me explore sensor integration, data visualization, and embedded system design using Arduino. It can also be expanded into a full IoT weather monitoring system using WiFi modules like ESP8266 or ESP32.

In this project, I built a DIY Arduino Weather Station using a DHT22 temperature and humidity sensor and a 0.96" OLED display with an Arduino Mega.The DHT22 ...

I recently built a Digital Clock using Arduino, DS3231 RTC Module, and 0.96" OLED Display (SSD1306) that displays:
✅ Real-Time Time
✅ Date (Day / Month / Year)
✅ Temperature (from DS3231 sensor)
The DS3231 RTC module provides highly accurate timekeeping thanks to its temperature-compensated crystal oscillator, making it much more reliable than basic RTC modules.
In this project, I worked with:
I2C Communication
RTC interfacing
OLED display integration
Embedded C (Arduino programming)
This project helped me strengthen my understanding of embedded systems and hardware interfacing.

In this video, I will show you how to build a Digital Clock using Arduino, DS3231 RTC Module, and 0.96" OLED Display (SSD1306). This project displays real-ti...
