Real-time gym equipment availability tracking system with IoT integration and AI-powered assistance for the AWS Hong Kong AI Hackathon 2025.
In Hong Kong's densely populated urban environment, gym facilities face significant challenges with equipment availability and member satisfaction. Peak hour congestion leads to:
- Wasted Travel Time: Members arrive at gyms only to find their preferred equipment occupied
- Poor User Experience: Long waiting times and unpredictable equipment availability
- Operational Inefficiency: Gym operators lack real-time insights into equipment utilization patterns
- Resource Planning Issues: Difficulty in optimizing equipment placement and maintenance schedules
GymPulse addresses these challenges through a comprehensive IoT-enabled platform that provides real-time equipment availability tracking across multiple gym branches. The system leverages AWS cloud infrastructure to process IoT sensor data, analyze usage patterns, and deliver intelligent insights through a modern web dashboard with integrated AI assistance.
This project extensively leverages Amazon Q Developer and AWS AI services to enhance the gym management experience:
- Code Generation: Used Amazon Q Developer to accelerate development of Lambda functions and CDK infrastructure
- Documentation Generation: Leveraged Q Developer for creating comprehensive API documentation and code comments
- Debugging Assistance: Utilized Q Developer's debugging capabilities to optimize performance and resolve integration issues
- Best Practices: Applied Q Developer recommendations for AWS security, scalability, and cost optimization
- AWS IoT Core: Processes MQTT sensor data for real-time equipment state tracking
- AWS Lambda: Serverless compute for real-time data processing and API endpoints
- Amazon DynamoDB: NoSQL database for storing equipment states and historical data
- Amazon API Gateway: RESTful APIs with rate limiting and WebSocket support
- CloudWatch: Comprehensive monitoring and alerting for system health and performance
