🩺 STM32/ESP32-Based Patient Monitor

🔗 View Project on GitHub

Custom-designed patient monitor using STM32F411CE and ESP32 for medical sensing and wireless data transmission. The STM32 handled signal acquisition from multiple sensors:

  • Gas sensors: MQ3, MQ4, MQ7, MQ135
  • ECG via AD8232
  • IR temperature sensor: MLX90614
  • Environment sensors: SHT3x
  • 1.8” RGB TFT display and rotary encoder with button

The ESP32, developed by a teammate, communicated with the STM32 over UART and pushed the data to a remote database with a PHP-based web interface.

🌡️ ESP32-Based Temperature Control System

🔗 View Project on GitHub

A FreeRTOS-based system designed to maintain and regulate the temperature of lab-scale thermal systems. Utilizes PID control to stabilize temperature, with UART communication and a graphical user interface.

  • Implemented on ESP32
  • Designed and routed PCB in KiCad
  • Real-time control with FreeRTOS + PID loop
  • GUI for parameter tuning and monitoring
