Self-Healing Mesh Network Node With Dynamic Routing

Software for this project is still under development

This repository contains the design and implementation files for a PCB that serves as a node in a self-healing mesh network, developed as part of my thesis project. The board incorporates 2.4GHz WiFi, Bluetooth, and an array of environmental sensors,a power management system, and is designed for battery-powered operation.

Features

• Mesh Networking: Designed for integration into a dynamic routing, self-healing mesh network. (Further details on the mesh networking protocol will come.)
• Wireless Connectivity: Integrated 2.4GHz WiFi and Bluetooth for communication and data transmission.
• Environmental Sensing:
  • BME280: Temperature, humidity, and barometric pressure sensing.
  • ZMOD4410: Air quality sensor with embedded artificial intelligence.
  • APDS-9250: Digital ambient light sensor (RGB and IR).
• Power Management:
  • BQ24073: Linear battery charger with power path for seamless operation during charging.
  • TPS62842DGRR: High-efficiency step-down switching converter.
• Battery Powered: Designed for low-power operation and extended battery life.
