List of items:
1) Arduino Uno or Yún
+ Ethernet Shield W5100 R3 for Arduino Uno
+ MQ2 and MQ135 Smoke Gas Sensor
+ DHT11 Temperature Sensor
+ Flame Firelight Sensor Module
2) Arduino Yún
+ Infineon Lighting RGB LED Arduino Shield (to connect RGB strip LED)
+ 2-Channel 5V Relay Module for Arduino (to connect lamp)
+ HC-SR04 Ultrasonic Ranging Detector Sensor for Arduino
+ USB webcam
My idea:
My idea is to create a management system for a smart house, in particular as regards the entrance area of the house.
With this system I can go to manage:
a) [1) Arduino Yún + ..] Video surveillance with selective events: when a person approaches the front door, the ultrasonic sensor detects, then Infineon Light RGB LED shield illuminates with white strips inside the room, with relè the external light to illuminate the door, active surveillance taking pictures and / or video recording (streaming), all for a certain time interval.
b) [1) Arduino Yún + ..] if it isn't on a "presence at the door", the LED strips are programmed to create relaxing effects or manifest according shades of blue and red the temperature currently present in the room.
c) [2) Arduino Uno(or Yún) + ..] detect temperature, humidity, presence of harmful gases and flame lit the stove and transmit the data in real time via MQTT.
In this way, with a dedicated web interface I can to have full control of the focal point of my house, checking parameters and real-time operation, guaranteeing me so that everything is in total safety. In fact I can be alerted with push notifications when particular events occur as abnormal temperatures, harmful gases or unexpected visits!
For the management of communications between the various nodes of the system will use the protocol MQTT going to take advantage of the wonderful tools provided by the Eclipse IoT Platform as I will list below.
First job preview: I installed in my VPS (Virtual Private Server | running Ubuntu) mosquitto (http://mosquitto.org/) through the following commands:
sudo apt-add-repository ppa:mosquitto-dev/mosquitto-ppa sudo apt-get update sudo apt-get install mosquitto-ppa
