This code will read the temperature and humidity. The results will be printed and stored in a MySQL database. There are a few graphs based on the data in the database.

The setup I created this project for is the following:

• Raspberry Pi (rev 2)
• SHT11 Humidity & Temperature sensor
• 20x2 LCD HD44780 Compatible

To download the code with git:

git clone git@github.com:dveeden/raspberry_pi_hygro.git

Copy the rpi-hygro.cnf.sample to rpi-hygro.cnf and adjust the settings to your configuration.

The sens.py must be ran by root:

nohup sudo ./sens.py &

Run graph-min-max.py and/or graph-overview.py. This must be done on a machine wich can access the database.

On the database macine:

• MySQL (Tested with 5.5)

On the machine which does the collection:

• Python
• MySQL Connector/Python
• Adafruit CharLCD
• rpiSht1x

On the machine which generates the graphs:

• Python
• MySQL Connector/Python
• matplotlib
