rpi-plant-project

An automatic plant watering system created with Python and a Raspberry Pi.

You can read more about how I created this project here.

Dependencies

• gpiozero library
  • Used for interfacing with the GPIO pins on the Raspberry Pi
• schedule api
  • Used for running Python functions at pre-determined intervals
• smtplib module
  • Used for sending emails
• ssl module
  • Used in tandem with the smtplib module

Installing

The gpiozero library should already be installed into your Pi by default but if not you can run the following command:

sudo pip3 install gpiozero

You can install the schedule api by running the following command:

sudo pip3 install schedule

To install this code onto your Raspberry Pi you can clone the repository to your Pi's Desktop by typing in the following command into the terminal:

git clone https://github.com/AlanConstantino/rpi-plant-project.git

Once cloned, you can move the "run" folder onto your Pi's desktop and then run the following command:

sudo crontab -e

Now you'll see a window that looks something like the following:

From here, you want to append the following code snippet to the file:

@reboot python3 /home/pi/Desktop/run/water_plant.py

By doing so, you're telling the Pi "Hey whenever you reboot, run the python script 'water_plant.py' inside the 'run' folder located on our Desktop."

Now you can turn off your Pi and whenever you turn it back on, the "water_plant.py" script will get executed.
