Overview
Built a personal project for monitoring temperature and humidity in my home office using ESP32 microcontrollers and DHT11 sensors. Data is transmitted via MQTT to a Node.js backend and displayed on a React dashboard.
Technical Stack
- Hardware: ESP32, DHT11 sensors
- Backend: Node.js, MQTT broker
- Frontend: React, Tailwind CSS
- Deployment: Vercel + Railway
Features
- Real-time temperature and humidity monitoring
- Historical data visualization
- Alert thresholds
- Mobile-responsive design
- Dark mode support
Lessons Learned
This project sparked my interest in combining hardware with web technologies. The intersection of physical devices and software is fascinating — and renewable energy monitoring is the perfect application.
