The model was created from 3mm thick balsa wood, it has a basement level for the electrinic wires, and here you can find the microcontroller which is used in this project, and an additional circuit. The base of this embedded system is an Arduino Mega microcontroller with an Ethernet Shield, which can make it possible to connect to the internet, and provide remote monitoring and remote intervention. Besides that an additional circuit is used in this project, which contain the MOSFET circuits. With the help of these circuits 12V power can be switched to the LED strip lights and the fan built in the model. This house gets information from it’s surroundings with a lot of variety of sensors, including a rain sensor, a gas/smoke sensor, a PIR motion sensor, and a light sensor. There is light control in one of the three rooms, which is made by the light sensor. Here an interfering signal can be created by the blinds placed in front of the window. In an other room a gas/smoke sensor is placed, and when it detects smoke or gas the system automatically opens the window and starts the ventilation system. If the window is opened and the rain sensor gives high signal the arduino automatically closes the window. In the garage the light is controlled by the PIR motion sensor. It serves practical reasons, and when we are not in the house in case of illegal entry it can switch the alarm system. The state of all of the sensors and servos can be followed with the help of an internet surface. The system can inform you via SMS or e-mail in case of a change of some sensors’s state.
