Overview
A biomedical sensor monitoring system that integrates vital sign sensors with wireless data transmission and real-time visualization. Bridges embedded hardware with a desktop application for medical data analysis.
System Architecture
Desktop Application (.NET 5 / WPF)
- Real-time Biomedical sensors visualization:

- Oximeter (Blood Oxygen Level, SpO₂) graph over time
- Tensimeter (Systolic/diastolic) and blood pressure (BPM)
- WiFi TCP/IP connection to ESP8266 (auto-discovery)
ESP8266 Serial-WiFi Bridge
- WiFi Access Point
- mDNS Service Discovery
