ESP32 DHT22 Temperature and Humidity (with LCD Display)

This project measures ambient temperature and humidity using a DHT22 sensor and displays the data in real time on a 16x2 I2C LCD. Data is read from the sensor using the one-wire protocol via the Adafruit DHT library. This project serves as the foundation for IoT weather stations, smart home automation, or environmental monitoring systems in greenhouses. Communication with the DHT22 is established via the ESP32's GPIO 4 pin.
