Project Title
Indoor Asset and Employee Tracking Using ESP32-Based IoT Framework
Scope
The scope of the project included:
- Development of a Wi-Fi-based indoor tracking system using ESP32 microcontrollers.
- Real-time tracking and location processing via a central server and client application.
- Designing an energy-efficient solution with a minimum of 6-month battery life.
- Integration with mobile/web platforms for real-time visualization.
Challenges
- Achieving accurate indoor positioning without GPS.
- Designing a low-power device that can last for at least 6 months on a single battery.
- Enabling seamless communication between multiple ESP32 nodes and a central server.
- Real-time data accessibility and scalability for future enhancements.
- Customizable hardware form factor for deployment in various locations (walls, racks, vehicles).
Solutions
Suventure developed an advanced ESP32-based IoT solution with the following implementations:
- ESP32-based Node Deployment: Devices were installed at fixed positions across the building to act as beacons or reference points.
- Signal Strength-Based Tracking: ESP32 modules collected signal strength (RSSI) from end devices to estimate their location.
- Centralized Data Processing: All signals were relayed to a PC/server that computed end-device positions based on triangulation algorithms.
- Mobile/Web App Integration: Real-time tracking information was pushed to MongoDB and visualized through custom dashboards and mobile apps.
- Low Power Optimization: The system was designed to last over 6 months per device using energy-efficient protocols and sleep cycles.
- Scalable Design: The architecture was scalable for future additions like environmental sensors or automated alerts.
