Portable Temperature Sensor System (ECE 341)
Embedded Files
This project was a portable temperature monitoring system built using an ESP32 microcontroller and LM75A temperature sensor. The system measured ambient temperature and displayed readings on an LCD screen while using stable voltage regulation for reliable operation. Hardware was assembled and validated through breadboarding, soldering, and experimental testing.

My role focused on hardware assembly and system documentation. I soldered the battery clip to the voltage regulator, validated power delivery using a digital multimeter, and created the top-level architecture diagram and system description. Collaboration with teammates supported troubleshooting, system integration, and successful project validation.
