Temperature & Humidity Monitor with LCD
Monitor environmental conditions using a DHT22 sensor and display readings on an LCD screen. Includes data logging capabilities.
Project Overview
Build a professional environmental monitoring station that tracks temperature and humidity in real-time! This project introduces you to working with sensors, LCD displays, and data logging.
The DHT22 sensor provides accurate temperature and humidity readings, while the 16x2 LCD display shows current conditions and historical data. You'll learn about sensor calibration, data validation, and user interface design.
This project is perfect for understanding how environmental monitoring systems work in buildings, greenhouses, or weather stations. The skills you learn here apply to IoT projects, home automation, and scientific data collection.
