25 IoT Projects Using Arduino & Sensors

Transform your ideas into smart, connected systems with this comprehensive Arduino IoT guide!

Whether you’re a hobbyist, student, or engineer, 25 IoT Projects Using Arduino and Sensors bridges the gap between theory and practice, empowering you to build real-world IoT solutions from scratch. This project-driven book combines clear explanations, full-color diagrams, and ready-to-use code to help you master the essentials of sensors, connectivity, and automation.

What You’ll Build:

• 🌡️ Environmental Monitors: Track temperature, humidity, and air quality (DHT11, MQ-135).

• 🚪 Smart Security Systems: RFID door locks, motion-activated alerts, and flood detectors (HC-SR04, PIR).

• 🌱 Agricultural Automation: Soil moisture sensors, smart irrigation, and greenhouse controls.

• 🏭 Industrial Solutions: Vibration analysis, predictive maintenance, and machine health monitoring.

• 🏠 Home Automation: Voice-controlled lights, gesture-based appliances, and cloud-connected mirrors.

• 🔋 Energy-Saving Tools: Solar-powered streetlights, IoT trash bins, and water level indicators.

Why This Book Stands Out:

• Step-by-Step Guidance: Every project includes circuit diagrams, component lists, and code explanations tailored for beginners and advanced users.

• Real-World Focus: Solve practical problems like flood alerts, pet feeding schedules, and bike theft prevention.

• Sensor Mastery: Learn to integrate 20+ sensors (ultrasonic, RFID, LDR, piezo, GPS) with Arduino and ESP modules.

• Cloud & Connectivity: Upload data to ThingSpeak, send SMS alerts via GSM, and control devices over Wi-Fi/Bluetooth.

• Troubleshooting Tips: Avoid common pitfalls with dedicated debugging sections for each project.

Perfect For:

• Makers and DIY enthusiasts eager to explore IoT.

• Students studying electronics, robotics, or computer science.

• Engineers prototyping industrial or home automation systems.

• Educators seeking project-based learning resources.
