piponic

IoT Monitoring and Control for Aquaponic and Hydroponic Systems Using Raspberry Pi.

Install

To install this project on the Raspberry Pi and have it run on boot, please run the following:

sudo ./install.sh <DEVICE-ID> <REGISTRY-ID> <PROJECT-ID>

Note that the parameters are as follows:

• <DEVICE-ID> string name to call the device (you choose)
• <REGISTRY-ID> string name of the Google IoT Registry (can be new or pre-existing)
• <PROJECT-ID> string name of the Google Cloud Project

Example:

sudo ./install.sh JaydenPi RaspberryPis piponics 

Important Notes:

• Please create a Google Cloud Project before running this script and enable the Google Cloud IoT Core API.
• The install will prompt you to login into your Google Account associated with your Google Cloud Project halfway through the process. Please follow the link and sign in
• The install process may take around 20 minutes

Checking Installed Software Status

The install script causes the piponic.py script to run when the raspberry pi boots. To do this, it uses a systemd service. In order to check on the status of the software (running or not, etc), run this command:

sudo systemctl status piponic.service

Note that the systemctl program manages systemd services like our piponic.service. So, to stop, start and restart our code from running, try the following commands:

sudo systemctl stop piponic.service
sudo systemctl start piponic.service
sudo systemctl restart piponic.service

Additionally, when testing, view logs using journalctl. Here is an example:

sudo journalctl -u piponic.service

Code Documentation

For use of sensor and control modules, the use follows:

import src.adc as adc
import src.temp as temp
import src.relay as relay

relay.init_one()
relay.on1()
relay.off1()

temp.read()

adc.read_pH()
adc.read_leak()
