Conventional home automation solutions often depend on cloud platforms, proprietary mobile apps, or offer only basic ON/OFF control of appliances. These limitations increase complexity, reduce reliability during internet outages, and restrict flexibility when scaling to control multiple devices or adding advanced features like variable fan speed control.
This project presents a standalone, Wi-Fi–enabled home automation system built on the IndusBoard Coin. The board hosts its own interactive web interface, allowing users to control AC appliances directly through a browser—without cloud services or mobile apps. In addition to relay-based switching, the system integrates PWM-based fan speed control, enabling smooth, real-time adjustment of fan speed from the web dashboard.
Key Features
- Standalone web-based home automation (no cloud, no app required)
- Runs in Wi-Fi Access Point (AP) mode by default
- Optional Station (STA) mode for integration with home Wi-Fi
- Control of multiple AC appliances (lights, fans, etc.)
- Relay-based ON/OFF switching for safe AC load control
- PWM-driven fan speed control using an AC fan speed controller module
- Real-time control via buttons and sliders on a web interface
- High scalability with 30+ GPIO pins available on the IndusBoard Coin
- Easily extendable to additional appliances and future sensors
Applications
- Smart home and apartment automation
- DIY and maker-based home automation projects
- Educational IoT and embedded systems labs
- Offline or local-network-based automation setups
- Scalable automation controllers for lights, fans, and appliances
- Foundation for integrating sensors like motion, temperature, or light
By combining relay-based switching with PWM fan speed control and a self-hosted web interface, this home automation system goes beyond basic smart switching. Its cloud-free, scalable design makes it reliable, flexible, and ideal for both real-world smart homes and learning environments—showcasing how IoT can deliver powerful automation with simplicity and control at the edge.
