WaterBase Smart Home IoT

Project Description

Pada sistem arduino menggunakan raspberry pi sebagai gateway. Gateway ini berguna untuk menghubungkan antar arduino dan antara arduino dam android. Arduino menerima input dari sensor IR dan DHT11. Hasil dr IR digunakan untuk menyalakan lampu sedangkan hasil dr DHT11 untuk menyalakan A/C. Arduino juga memiliki lcd dan 7 segment untuk menampilakan status dari keadaan IOT pada rumah.

Installation

Dependencies

Robot Operating System (ROS), Kinetic Version (middleware for robotics, see installation manual),
rosserial (ROS serialized messages wrapper)
rosserial_client (generalized client side source for rosserial)

rosserial_python (Python-based implementation of rosserial)

  sudo apt-get install ros-kinetic-rosserial ros-kinetic-rosserial-client ros-kinetic-rosserial-python

arduino_msgs (package containing custom messages used by Arduino)

Building

ROS Workspace

The system runs in a ROS environment. Create a workspace for the system using

mkdir -p ~/<your_workspace>/src
cd ~/<your_workspace>
source /opt/ros/kinetic/setup.bash #or setup.zsh if you're using zsh
catkin_make
source devel/setup.bash #or setup.zsh if you're using zsh

note: every new terminal must be sourced by using source /opt/ros/kinetic/setup.bash and source devel/setup.bash

Then in src directory, clone every package from here. You should now have 3 folders in src directory, one for each package with corresponding names. Then, on your workspace directory (~/<your_workspace>), build the workspace by using

cd ~/<your_workspace>
catkin_make
source devel/setup.bash #or setup.zsh if you're using zsh

Arduino

Simply clone this directory and open to Arduino sketchbook directory (Linux default is ~/Arduino) using

git clone https://gitlab.informatika.org/if3111-2019-waterbase/arduino.git
cd arduino
mkdir ~/Arduino/actuators && mkdir ~/Arduino/sensors
cp actuators.ino ~/Arduino/actuators/
cp sensors.ino ~/Arduino/sensors/

Now generate ROS library for Arduino. Go to your ROS workspace directory, generate the library, and copy them to Arduino libraries folder (Linux default is ~/Arduino/libraries) using

cd ~/<your_workspace>
rosrun rosserial_client make_libraries . arduino_msgs
cp -R ros_lib ~/Arduino/libraries/

Next, launch Arduino IDE and open actuators.ino and sensors.ino. Now, connect the Arduino for sensors to /dev/ttyACM0 and the Arduino for actuators to /dev/ttyACM1. Upload each .ino files to corresponding Arduinos.

Android

Simply go to the project repository and follow the instructions.

System Setup

Connect the Arduino for sensors to /dev/ttyACM0 and the Arduino for actuators to /dev/ttyACM1.

Open 3 terminals (or, if you're fancy, you can use terminal multiplexer like tmux, whatever), then on each terminal type in the following commands.

 cd ~/<your_workspace>
 source /opt/ros/kinetic/setup.bash #or setup.zsh if you're using zsh
 source devel/setup.bash #or setup.zsh if you're using zsh

On the first terminal run roscore by using
```
 roscore
```
On the second one, run the API server node using
```
 rosrun network_api network.py
```
On the third terminal, launch the hardware interface nodes by typing in
```
 roslaunch hardware_controller hardware_interface.launch
```

And you're all set.

Usage

Switching devices on and off

You can open the Android app, go to Home IoT tab and tap the lights or A/C that you want to switch on or off.
Checking the status of the system

The system control panel (connected to the Arduino for sensors) has one push button, an LCD screen, and a 4-digits seven-segments display. The default message on the LCD screen is a greetings message. Push the button once and it will switch to show the temperature measurement. Push once again, it will show the humidity measurement. Push it once more and it will be showing back the greetings message. The seven-segments display always shows the current temperature reading.
