DHT11 Live Plotter
Cloud · Board: ESP8266 · Day 36 of 100
Stream DHT11 readings from the ESP8266 into live Matplotlib graphs on your PC. Sensor data visualization with Python.
How it works
The ESP8266 streams temperature and humidity readings over USB serial as plain text lines. A Python script on the PC parses each line and appends the values to a live Matplotlib chart, so you watch the sensor's behavior unfold as a moving graph instead of scrolling numbers.
What you'll learn
- Serial data streaming
- Live data plotting
- PC-side Python tooling
- Sensor behavior visualization
