š Introducing AtmosTrack ā A Real-Time Temperature & Pressure Monitoring System
Iām excited to share AtmosTrack, a real-time atmospheric temperature and pressure monitoring system that I recently developed. This project is built to reliably monitor environmental conditions and display the readings on both a serial monitor and a 16×2 LCD.
š§ Key Technical Highlights
š”ļø Sensor
Bosch BMP280 ā chosen for its high accuracy in temperature and pressure measurement.
š Communication Interfaces
- SPI ā High-speed communication between the BMP280 sensor and the ATmega328P
- UART ā Transmits processed data to the serial monitor
- Parallel Interface ā Drives the 16×2 LCD display
š§© Modular Firmware Architecture
The firmware is fully written using a modular coding approach, resulting in cleaner, scalable, and reusable code ā ideal for future embedded projects.
š Hardware
The complete hardware schematic and circuit details are included for anyone interested in replicating or extending the design.
š ļø Bare-Metal Development
AtmosTrack is developed entirely using bare-metal programming on the ATmega328P ā no external libraries or frameworks were used.
All peripheral drivers, including SPI, UART, LCD (parallel), and BMP280 communication, are written from scratch to ensure full hardware control and deeper understanding of each module.
The architecture is purposefully kept modular and extensible, making it easy to add future enhancements such as:
- Data logging
- Wireless communication
- IoT/cloud integration
