Arduino GPS Project

This project is an ESP32-based GPS and sensor tracking system that logs location and environmental data, then visualises it on a Flask webserver with an interactive Leaflet map.

Features

• ESP32 hardware
  • NEO-6M GPS module: Captures location data
  • DHT22 sensor: Measures temperature and humidity
  • SD card module: Stores data while offline, provides configuration options
  • Portable Battery and Project case: Designed for outdoor use and mobility
• Backend
  • Python Flask webserver: Serves the frontend and data endpoints
  • PostgreSQL with PostGIS: Stores location data and performs spatial queries
• Frontend
  • Leaflet.js: Displays location data on an interactive map
  • Bootstrap: Provides clean UI with rapid prototyping
  • flatpickr: Date picker for filtering data
  • TypeScript, HTML, CSS: Frontend languages built with Webpack

A project for me to learn a geospatial stack and build a full-stack application from scratch, bringing in my love for microcontrollers and IoT.
