Monitoring Temperature and Humidity

My project is based in get data from a temperature/humidity sensor DHT11 with 'Arduino UNO' and plot a living graph with the data with Python.

I can divide this project in 4 steps:

• Assemble the circuit
• Program Arduino UNO
• Get data from python
• Plot the living graph

And those are the materials:

• Arduino UNO with USB cable for Arduino (or any other material that allow you to write a code in Arduino)
• DHT11 (Temperature/Humidity sensor)
• Protoboard (Optional)
• Wires/Jumpers

Arduino Libraries:

• dht.h (I uploaded it here)

Python Libraries (you can install them with 'pip install'):

• matplotlib
• drawnow
• pyserial

Assembling the circuit

DHT11 Sensor:

Arduino UNO:

Squematic:

Assembled circuit:

We can see that I put the '-' terminal of DHT11 at ground, middle terminal at VCC +5V (Arduino) and 'S' terminal for data at pin '8'.

Results

Arduino Results

The serial port works fine.

Python 'getting_data.py' Results

We get data from COM3 with sucess!

Python 'plotting_tu.py' Results

And finally our living graph! I hope you learn from this git and could replicate it.
