Winter Semester 2018/2019

First and foremost, in the previous research and projects of home automation system,
most of them are only simulated with a prototype or
model, but not implemented in a real-life application. For example,
they are using a small LED to represent as a real lamp in a
home automation system. However, the requirement of the supply power
for a small LED is different from the lamp in a real home automation
system. Therefore, battery as a power supply is not sufficient for a real-life application lamp.
Hence, we will make this project with a real-life application system.
In addition, according to our market research on existing technology,
the existing products are real-life application systems, but most of the product will only use short distance device control especially the connect from router to controller.
As an example, there are some home automation systems are using Digital Enhanced Cordless Telecommunication (DECT) to communicate between router and controller of devices.
Therefore, in this project, we will use Wi-Fi as a medium of communication between router and controller.
Besides, the existing products in market have less function and more expensive.
As an example, most of the products can only either switch on and
switch off the devices, but not adjust the performance of the device.
Hence, this project will be produced with more functions and the cost will be reduced compare to the existing products.
Basic Flow Chart of System
Basic Concept of the System
Table 3.9.1: Manual control mode by user through Browser.
Table 3.9.2: Automatic control mode.
In this project, user can control their light in their home with this system. This system is divided into 2 mode which are the automatic mode and manual mode.
Web Interface of the System
In this web browser interface, user can connect their system wia Wi-Fi. After user connect it to their system, user can know the light intensity in their room.
User can also know the light status whether is on or off. If the light is on, the user are not allow to click "On" button in the browser. However, if the light is off, the user can click "On" button to on the light in room.
Basic Electrical Flow of the System
The rating of fuse that we will use in this system is
Basic Mechanical Concept of the System
In this system, PIR Motion Sensor and Light Intensity Sensor will be embeded in
Besides, there is a switch to switch on and off the whole system. This is to ensure that user will plug-in properly before they start to use it, to prevent any electric shock.
There is also a green LED to notify user that the power of this system is on.
1. Temperature Control
2. Combine with other existing
Testing of the Sequence
1. Automation mode
Besides, a Mosfet Driver had also been tried for this automation mode of the system.
When the brightness in the home is low and there is moving object in the room, the light will turn on and it will feedback to browser to inform user.
2. User-Browser Manual Mode
User can on or off their system through the Browser.User can also know their the brightness in their room.
