Introduction
Agriculture is evolving with technology, and automated greenhouse systems are a game-changer. Traditional greenhouses require manual monitoring, but an IoT-powered system can manage optimal conditions for plant growth efficiently. In this project, you’ll integrate sensors with Arduino to automate a greenhouse, ensuring plants receive the perfect balance of light, temperature, and moisture.

Did You Know?
The global smart agriculture market is projected to reach $25 billion by 2027, with automated greenhouses playing a key role.
Automated greenhouses can reduce water wastage by up to 30% compared to traditional farming methods.
How It Works
The system uses sensors to collect real-time data on temperature, humidity, and light levels inside the greenhouse. Based on this data, the Arduino microcontroller controls actuators such as fans, heaters, and water pumps to maintain ideal conditions for plant growth.
Components at Work:
Temperature & Humidity Sensor: Measures the internal environment.
Light Sensor: Detects sunlight levels.
Arduino Board: The brain of the system, processing sensor inputs.
Relays & Actuators: Control water pumps, heaters, and fans.
LCD Display (Optional): Shows live data readings.
