Design and implementation of a wireless vibration monitoring system using ESP32 and mesh networking
Course: Electronic Project I & II
Design and implementation of a wireless vibration monitoring system based on ESP32 nodes for detecting vibration patterns and providing local visual alerts. Each node incorporated LED indicators to display warning information, including directional alerts, as well as high-intensity white LEDs that allowed the device to operate as a lighting unit. The nodes communicated through a mesh network, allowing vibration information and system status to be transmitted between devices and collected on a central laptop for monitoring. The project involved 3D mechanical design, PCB design, internal electronic integration, prototype assembly, and experimental testing. I was responsible for the 3D design, PCB design, and integration of the internal components. I also performed prototype testing and worked with my team to optimize the embedded software and communication network. 
Prototype Development
Final Prototype Assembly
Final assembly of the vibration monitoring node, integrating the custom electronics and enclosure into the experimental installation.
Custom PCB Design and Fabrication
Custom PCBs designed for the monitoring nodes, providing the electrical interconnections required for the ESP32, sensing, communication, power, and signaling components.
LED Indicator Integration
Integration of the LED signaling system into the enclosure, providing visual alerts and additional white illumination as part of the monitoring node.
Internal Electronics Integration
Internal assembly of the monitoring node, integrating the ESP32-based control electronics, custom PCB, power circuitry, communication hardware, and associated components inside the enclosure.
