Digital Thermometer using DHT22 and Arduino

The Digital Thermometer project uses a DHT22 sensor and Arduino Uno to accurately measure and display temperature and humidity. The DHT22 is a digital sensor that provides precise readings, making it ideal for environmental monitoring projects.

The sensor sends data to the Arduino, which processes it and displays the values on a 16×2 LCD display. By using an I2C module with the LCD, the wiring is simplified and only two Arduino pins are needed for display communication.
