PIrrigator

An irrigation control system based on a Raspberry PI

This application allows controlling a set of valves connected via I2C to a Raspberry PI.

It allows a private scheduling program for each valve, along with manual control via WEB interface optimized for mobile devices.

Software part includes a PHP background process which runs the scheduling program, and a WEB page composed of HTML combined with PHP.

Hardware part includes:

Installation instructions: ***** NOT Updated ******

  1. Get a Raspberry PI and connect it to your local network.

  2. On the PI, install Apache, PHP, Samba, FTP, I2C... Setup apache and PHP apt-get install apache2 php5 i2c-tools php-pear

  3. add these lines to /etc/apache2/mods-enabled/php5.conf <FilesMatch ".+.html$"> SetHandler application/x-httpd-php

  1. Enable I2C - follow https://www.abelectronics.co.uk/kb/article/1/i2c--smbus-and-raspbian-linux chmod 777 /dev/i2c*

  2. Set dynamic DNS add systemd service to run the following command every 5 minutes wget -O - http://freedns.afraid.org/dynamic/update.php?WkNicER4UGprSUxEVGl3eW1VY0Q6MTE2MTcyNTM= &> /tmp/freedns_michaeli_mooo_com.log

    Add root SMB share: sudo apt-get install samba samba-common-bin winbind smbclient a. nano /etc/samba/smb.conf uncomment line: "name resolve order = lmhosts host wins bcast" uncomment line "security = user" in SHARES add: [root] comment = Root share path = / valid users = @users force group = users create mask = 0660 directory mask = 0771 read only = no b. usermod pi -G users c. smbpasswd -a pi
    d. sudo service smbd restart

?? d. nano /etc/nsswitch.conf ?? add wins to end of hosts line

a. nano /etc/apache2/apache2.conf add to the end:

Set ServerName

ServerName localhost

Add PHP in HTML support

AddHandler application/x-httpd-php .html

b. apachectl -k restart

c. enable I2C
sudo nano /etc/modules i2c-bcm2708 i2c-dev if any problems see https://www.raspberrypi.org/forums/viewtopic.php?t=97314

Add root FTP share apt-get install vsftpd a. nano /etc/vsftpd.conf anonymous_enable=NO local_enable=YES write_enable=YES b. sudo /etc/init.d/vsftpd restart

Add Hebrew

a. Enable root user in xbian-config

b. su

c. dpkg-reconfigure locales

d. select he_il UTF-8

  1. If you want to access it from the internet, register with a dns service. I use http://freedns.afraid.org/
  2. Create a directory called /var/www-data/valves and give the user www-data full access to it.
  3. Copy the demo valves INI files from demo-valve to the above directory.
  4. Run the background process deamon.sh Connect via SSH to your PI, cd to /var/www, type ./deamon.sh
  5. That it. You can open the webpage from a browser and play with it.

Set cron to reboot at 3AM sudo nano /etc/crontab -e 0 2 * * * root reboot

Notes

  1. If you don't have any HW connected, it will say 'NO HW FOUND - Simulation mode'. This will allow you to play around with it, without actually buying or connecting any HW.
  2. Clicking on the header image will return you to the main page.
  3. For now I'm using random images from lorempixel to have something colorful on the page... It should be replaced with real images to improve performace a bit.
  4. Deamon logs, named mutex files etc. will be created in /var/www-data/valves.

You may use it free for personal use, for commercial use please contact me at micronen@gmail.com If you have any questions, comments or ideas, you can contact me at the above email.
