Traditional home automation systems often rely on cloud services, mobile apps, or simple ON/OFF relay control, limiting real-time responsiveness, scalability, and flexibility. Controlling multiple appliances and adjusting fan speeds smoothly is rarely achievable in compact, DIY setups.
This project uses the IndusBoard Coin V2 (ESP32-S2-based, 3.3 cm board) to create a real-time, web-controlled home automation system. It allows users to wirelessly control multiple AC appliances, including lights and fans, directly from a browser. The system integrates relay modules for switching and a PWM-based fan speed controller for smooth fan adjustment. It operates in Wi-Fi Access Point mode by default but can also function in Station mode, connecting to existing home networks.
Key Features
- Real-time control of multiple AC appliances via web interface
- PWM-based fan speed control for smooth adjustment
- Independent operation in AP mode or integration into home Wi-Fi in STA mode
- Scalable design with 30+ GPIO pins for future expansion
- Safety ensured via relay isolation from high-voltage AC circuits
- Interactive web UI with buttons and sliders for seamless control
Applications
- Smart home lighting and fan automation
- Energy-saving automation by scheduling appliance operation
- Scalable DIY smart home projects with multiple devices
- Integration with sensors (temperature, motion, LDR) for advanced automation
This project demonstrates how a compact IndusBoard Coin V2 can serve as the central brain for a scalable, real-time, and interactive smart home system. It enables safe and smooth control of multiple AC appliances, offering an efficient, expandable, and fully DIY-friendly solution for modern home automation.
