Week 11

Prototype Development – Core Functions Successfully Tested

We’re happy to report strong progress on our prototype! Over the last weeks, we’ve been testing each core component individually, and the results so far have been encouraging.

✅ What’s been tested successfully:

- LoRa communication: Devices are exchanging data reliably in peer-to-peer mode  
- GPS tracking**: Working, though with some expected signal constraints in indoor areas  
- Heart rate sensor: Providing stable readings  
- User position and fall detection: Sensor logic is correctly identifying body posture and sudden movement events  
- Temperature module: Development started and first tests underway  

Each component has passed initial checks and is performing as expected.

🔧 What’s next:

We’re now moving to the integration phase, where all subsystems will be combined into one cohesive system. Once integrated, we’ll begin more rigorous testing — both in controlled environments and real-world scenarios — to ensure everything runs smoothly and reliably for the EletroDay presentation.

Technical Snapshot

Our ESP32 microcontrollers are programmed to:

- Read data from the heart rate, temperature and position/fall sensors  
- Send and receive packets via LoRa in peer-to-peer mode
- Collect GPS coordinates and respond to motion or fall-based events  

Each microcontroller works independently, allowing a modular and decentralized setup. This makes the system more flexible, resilient, and easier to debug — ideal for real-world use during testing and demonstration.
