Emergency response platform web experience

Website
The ResQMesh website includes both the public landing site and the secured admin command-center. The landing page introduces the system, provides information for users, supports registration, contact, password reset, and app downloads, while the admin dashboard manages civilian accounts, rescuers, rescue teams, mesh devices, distress deployments, reports, online department chats, and operational monitoring.

Mobile App

Emergency coordination for civilians and rescuers

Mobile App
The ResQMesh mobile app is used by civilians and rescuers in both online and mesh/offline modes. It supports distress activation, cloud and mesh chat, voice messages, active maps, rescue routes, notifications, rescuer location sharing, and emergency coordination even when internet access is limited. I developed this app in Expo using TypeScript.

Hardware + Mesh Node

Portable emergency communication device

The ResQMesh Communication Device is a portable emergency communication node for situations where cellular networks, internet access, or regular communication infrastructure are unavailable. It works as the physical mesh node that connects the mobile app with other ResQMesh devices.

It runs on an Orange Pi Zero 3 with a LoRa E22-400T30D-V2 radio module for long-range communication, GPS for location tracking, and power monitoring for battery awareness.

Key Components
  • Orange Pi Zero 3 - main controller
  • EBYTE E22-400T30D-V2 LoRa module - long-range mesh communication
  • NEO-6M GPS module - location tracking
  • INA219 power monitor - voltage and current monitoring
  • 3S LG MJ1 18650 battery pack with BMS - portable rechargeable power

The device provides the hardware layer for offline messaging, distress coordination, GPS sharing, and emergency communication between mesh nodes.

Offline emergency mesh node firmware

The ResQMesh device firmware powers the Orange Pi-based mesh nodes used for offline emergency communication. Each node manages LoRa packet transmission, mesh discovery, text and voice message relaying, distress alerts, GPS updates, local hotspot access, and synchronization with the ResQMesh website when internet becomes available. The firmware also supports OLED status monitoring for node identity, hotspot, firmware health, internet state, LoRa signal strength, packet activity, and battery percentage through INA219 telemetry.
