The main control application of Aquarium control implements the following features:
- Data acquisition of water temperature, pH and conductivity
- Data acquisition of ambient temperature and humidity
- Fresh water refill control
- Feed control
- Water temperature control using air ventilation and heater
- Calculation of refill tank content based on water level measurement
- Actuation of pump for water exchange
Additionally, the main control application implements the following supporting features:
- HW-Tests
- Text-To-Speech interface
- Logging
- Command interface to receive instructions from outside of the application
- Storage of recorded data in SQL database
- File-based communication to web application
- Monitoring and repair of relay board state
- Device Scheduling
The control application makes extensive use of the pigpio library.
The architecture of the application uses various threads.
The application is automatic start by using systemd.
Installation
for the installation of the operating system on the Raspberry Pi, please follow the instructions of the Raspberry Pi foundation. Use the 64-bit version.
Clone the repository, build and install the control SW
Create the folder with the usage rights:
sudo mkdir /usr/local/src/aquarium-ctrl
sudo chown pi /usrlocal/src/aquarium-ctrl
cd /usr/local/src/aquarium-ctrl
Next, clone the repository:
git clone https://in-dubio@bitbucket.org/in-dubio/aquarium-ctrl.git
Install the required libraries:
bash libinstall.sh
Enable I2C on Raspberry Pi
See detailed instructions how to use rasp-config.
Create a file for the message queue
The file is automatically created when running make install.
Alternatively, run the command sudo touch /var/local/aquarium-ctrl.mq.
The file is defined in the source file UsrIntrfc/MsgQu.h.
Create a ramdisk
Create the folder /mnt/ramdisk.
Add the following line to /etc/fstab: tmpfs /mnt/ramdisk tmpfs nodev,nosuid,size=50M 0 0.
Add a symbolic link using the command ln -s /mnt/ramdisk /var/local/aquarium-ctrl.
Automatic start of control application
Follow instructions for configuring automatic start of control application.
Create the website
In the folder /var/www/html, create the website using git clone https://in-dubio@bitbucket.org/in-dubio/aquarium-web.git.
Change the owner of the website to user pi and change the group of the website to www-data.
Create a symbolic link to the log file running ln -s /var/log/aquarium-ctrl-session.log /var/www/html/aquarium-web/logfile.txt.
Create the file /var/www/app.ini with the following content (set the correct password):
[database]
server = localhost
port = 3306
user = aquarium
password = YourPassword
database = aquarium
Download and install the node JavaScript libraries.
Setup of database
- Download or clone an SQL database dump:
git clone https://in-dubio@bitbucket.org/in-dubio/aquarium-database.git - Import a database.
- Create the user
aquariumand assign access rights to theaquariumdatabase. - Check the user rights using phpmyadmin
