Growbox

Code for my smart growbox experiment.

Growbox control based on Raspberry Pi. Supported devices/sensors:

• Themperature sensors: DS18B20
• 16-Bit ADC: ADS1115
• Multiple channel relay
• Humidity and Temperature Sensor: Si7021-A20
• PWM fans control
• CO2 and Temperature Sensor: MH-Z19

Prepare

• sudo apt-get install -y python-smbus
• sudo apt-get install -y i2c-tools
• Enable 1-Wire on your Raspberry Pi
• Enable I2C on your Raspberry Pi
• Install requirements.txt for project Python environment
• create config/db.py with the following content

USER = '***'
PASSWORD = '***'
DATABASE = '***'
HOST = '***'
PORT = '***'

Running

Works only with sudo because of CO2 sensor use /dev/serial0 which requires root permission

sudo python3 growbox.py

Run as a service

sudo apt-get install supervisor

Create a config file for your daemon at /etc/supervisor/conf.d/growbox.conf

[program:growbox]
[program:growbox]
directory=/home/pi/growbox
command=sudo python3 growbox.py
autostart=true
autorestart=true
stderr_logfile=/home/pi/growbox/logs/supervisor.err.log
stdout_logfile=/home/pi/growbox/logs/supervisor.out.log
stdout_logfile_maxbytes=0

Restart supervisor to load your growbox.conf`

sudo supervisorctl update
sudo supervisorctl restart growbox
