Circuit Documentation

Summary of the Circuit

This circuit integrates an ESP32 microcontroller with a DHT11 temperature and humidity sensor and an LCD I2C display. The ESP32 serves as the central processing unit, reading data from the DHT11 sensor and displaying the information on the LCD screen. The DHT11 sensor provides ambient temperature and humidity readings, while the LCD display offers a user interface to show these readings in real-time.
