DHT11 Web Server
Sensors · Board: ESP32 · Day 3 of 100
The ESP32 serves a live web page showing temperature and humidity from a DHT11 sensor. Your first step into Wi-Fi, HTTP servers, and sensor dashboards.
How it works
The ESP32 joins your Wi-Fi network and runs a tiny HTTP server in a loop. Each time a browser requests the page, the board reads temperature and humidity from the DHT11, injects the values into an HTML template, and sends it back. Refresh the browser and you get a fresh reading.
What you'll learn
- Wi-Fi station mode
- HTTP request/response cycle
- Single-wire sensor protocol
- Dynamic HTML generation
