Steps:
1. Set up and configure the sensors to collect atmospheric data.
2. Connect the sensors to the Arduino and write code to convert raw sensor readings into readable metrics.
3. Use an LCD to display these metrics in real time.
4. If utilizing a Wi-Fi module, upload data to a cloud platform for remote access.

Creating a weather station allows you to deepen your understanding of environmental science while honing your technical skills.

3. Smart Garden System

A smart garden system is a futuristic approach to gardening that combines technology with nature. This project helps you manage plant care remotely by automating processes like watering and monitoring soil health.

What You’ll Need:
– Arduino
– Soil moisture sensors
– Water pump
– Relay module
– Wi-Fi module (optional)
– Smartphone app interface

Overview:
Develop a system that checks the moisture level in your plants’ soil and waters them automatically when needed.

Steps:
1. Establish your sensors in the soil to measure moisture levels.
2. Control the water pump through a relay which activates when moisture levels fall below a set threshold.
3. For advanced users, connect to a Wi-Fi module to remotely monitor soil conditions.
4. Use an app to receive updates and control watering schedules.

This project not only simplifies plant care but also teaches you valuable lessons about automation and data-driven decision-making.
