Features

  1. Change graph generation to gnuplot.
  2. Added additional graphs for wind and battery voltage.
  3. Add support for BME680
  4. Add support for DS18B20
  5. Increase resolution of the weight from xxx.xx to xxx.xxx
  6. Added video monitoring with RasPi Cam.

Install gnuplot

sudo apt-get install gnuplot


add -r Retries option to driver wrappers

The maximum number of retries to read a sensor before giving up can be specified.

The shell script wrappers around the sensor drivers (dht22.sh, hx711.sh, hx711py.sh, etc) now accept a -r retries command line argument.

#
# Get the command line options (which device/GPIO pin to read), maximum number of times to try reading the sensor
#
while getopts "d:r:" option
do
        case "${option}"
        in
                d) DEVICE=${OPTARG};;
                r) MAXRETRIES=${OPTARG};;
        esac
done 

#
# If max number of retires not specified, default to 10
#
if [ -z $MAXRETRIES ]
then
  MAXRETRIES=10
fi 

#echo "DEVICE = $DEVICE"
#echo "MAXRETRIES = $MAXRETRIES"
#
# Loop up to MAXRETRIES times trying to read the sensor
#

DATA_GOOD=0
COUNTER=0
while [ $COUNTER -lt $MAXRETRIES ] && [ $DATA_GOOD -eq 0 ]
do



In config.pl, the -r1 option is added to the command line when the driver is called:


  if ( $hive_weight_sensor eq "cpw200plus" ) {
           $raw_hive_weight=`/usr/bin/sudo /home/hivetool/cpw200plus.sh -r1 -d $hive_weight_device`;
       }
  elsif ( $hive_weight_sensor eq "HX711") {
      $raw_hive_weight=`/usr/bin/sudo /home/hivetool/hx711.sh -r1 2>&1`;
       }
   elsif ( $hive_weight_sensor eq "HX711py") {
      $raw_hive_weight=`/usr/bin/sudo /home/hivetool/hx711py.sh -r1 2>&1`;
       }

Update, upgrade

update your system's package list and then upgrade all your installed packages to their latest versions:

sudo apt-get update
sudo apt-get dist-upgrade

Install RPi-Cam-Web-Interface

https://elinux.org/RPi-Cam-Web-Interface

First install motion:

sudo apt-get install motion

Then install RPi-Cam-Web-Interface

git clone https://github.com/silvanmelchior/RPi_Cam_Web_Interface.git
cd RPi_Cam_Web_Interface
./install.sh

Remove packages we don't need

sudo apt-get remove --purge scratch dillo squeak-vm sonic-pi
sudo apt-get autoremove
sudo apt-get clean
rm -rf /home/pi/python_games
sudo rm -rf /opt/minecraft-pi

Install packages we need

sudo apt-get -y install gawk bc libusb-dev libexpat1-dev sqlite3
sudo apt-get -y install dh-autoreconf libudev-dev
sudo apt-get -y install gnuplot

Install perl modules

sudo cpan CGI Date::Format XML::Simple DBI DBD::SQLite Chart::Gnuplot
sudo cpan DateTime


Install perl DateTime module

apt-get install libcgi-pm-perl
apt-get install libxml-perl
apt-get install libxml-simple-perl
apt-get install libdatetime-perl
apt-get install libdbi-perl
apt-get install libdbd-sqlite3-perl
apt-get install libchart-gnuplot-perl

Web Server

Configure apache

  1. Link the cgi.load and include.load module to mods-enabled
    ln -s /etc/apache2/mods-available/cgi.load /etc/apache2/mods-enabled
    ln -s /etc/apache2/mods-available/include.load /etc/apache2/mods-enabled
  2. Add .pl to AddHandler cgi-script
    sudo vi /etc/apache2/mods-enabled/mime.conf
    uncomment #AddHandler cgi-script .cgi (around line 219) and add ".pl .py" so it looks like:
    AddHandler cgi-script .cgi .pl .py
  3. add Includes and +ExecCGI to Options:
    sudo vi /etc/apache2/apache2.conf
    In stanza <Directory /var/www/>
    change
    Options Indexes FollowSymLinks
    to
    Options Indexes FollowSymLinks Includes ExecCGI
  4. Add index.shtml to DirectoryIndex:
    sudo vi /etc/apache2/mods-enabled/dir.conf
    Change
    DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm
    to
    DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm index.shtml
  5. Set up apache to listen on port 8080 if using port forwarding:
    sudo vi /etc/apache2/ports.conf
    add Listen 8080
  6. Copy 000-default.conf to sites-enabled and add port 8080
    cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-enabled/
  7. Edit /etc/apache2/sites-enabled/000-default.conf and add port 8080
    vi sites-enabled/000-default.conf
    and change the first line to:
    <VirtualHost *:80 *:8080>
  8. Turn off logging for video frames
    vi sites-enabled/000-default.conf
    CustomLog ${APACHE_LOG_DIR}/access.log combined env=!dontlog
    SetEnvIf Request_URI "^/cam_pic.php$" dontlog
  1. Restart Apache
sudo apachectl restart   or      sudo/etc/rc4.d/S02apache2 restart

Set sudo user privileges for Apache

This is necessary to allow config.pl to read the sensors. Run visudo to edit the sudo config file:

sudo visudo

and insert these line in the "User privilege specification" section:

# User privilege specification
