# DHT11 Live Plotter

Day 36 of the 100 Days 100 IoT Projects collection. Board: ESP8266.

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
