The main door is driven by the geared DC motor and as it has to close and open the door, it has to be moved bi-direcionally. To do so, we used the four BC107 NPN transistor based H-bridge bidirectional motor driver circuit interfaced to the digital output of the microcontroller. The microcontroller can digitally control the motion and direction of the motor to open and close the door.
It is also possible to add a temperature sensor by adding an ADC to the microcontroller to switch on the air-conditioning system depending on temperature variations. GSM, Internet, and speech recognition techniques are successfully merged in a single wireless home automation system that offers a complete, low cost, powerful and user friendly way of real-time monitoring and remote control of a house. An attempt is made to design smart phone based home automation system using Intel microcontroller AT89C52 and Bluetooth device and a Bluetooth enabled smart phone paired with the HC05 which is interfaced with the microcontroller. Sarthome or home automation provides a better standard of living at home with low-cost design and a user friendly interface and smart home system also provides more safety control over the electrical switches with some power saving methods. The usage of modern electronic communication devices like Android mobiles has increased with the advancement in mobile communication technology. There are abundant Android applications for different types of purposes.
Android Based Home Automation Systems and Its Applications
Monitor status of your home like temperature inside and outside of your home,light intensity inside and outside of your home, motion on the main entrance,LPG leak in the home and status of you main door. In this project 5 volt 700 mA Samsung charger is used for giving the power to the circuit and made of switch mode power supply. Simple instruction to let you know how to control an AC voltage device using an IR remote control and the Arduino.
Therefore, it's a good choice to design a home automation for luxurious life. Home automation can allow you to make the things that you need and do in your home easier to accomplish. Or, perhaps you want to voice automate the lights in your home so that you can get into bed and then turn the lights out. Or, perhaps you want to be able to control your sound system from any place in your home. No matter what it is you are looking to accomplish, home automation products are probably available to help you to make it happen. A typical home automation system allows one to control house hold appliances from a centralized control unit.

After that the regulated supply is fed to all the sensors ,relays and the microcontroller. The main objective of this project is to develop a home automation system using an Arduino board with Bluetooth being remotely controlled by any Android OS smartphone. Modern houses are gradually shifting from conventional switches to centralized control system, involving remote controlled switches. Presently, conventional wall switches located in different parts of the house makes it difficult for the user to go near them to operate. Even more it becomes more difficult for the elderly or physically handicapped people to do so.
The simple TONER TRANSFER METHOD is used here to develop PCB at home. The ANDROID client will use bluetooth to wirelessly connect to the host device. Automate your indoor lightening, outdoor lightening and fan/AC to switch ON/OFF automatically when the light intensity and temperature conditions exceed the programmed threshold values.(This feature, we named it “SENSOMATE”). Control Risks supports hybrid working arrangements, wherever possible, that emphasise the value of in-person time together - in the office and with our clients - while continuing to support flexible and remote working. The smart home app is tested and it is able to successfully perform the smart home operations such as switching functionalities, automatic environmental control and intrusion detection, in the later case where an email is generated and the siren goes on.

A software feedback is implemented between the motor and the door hook sensor output so that when the door reaches its max position and is being shut the motor stops driving the motor to prevent any damage. Here is a simple and compact security alarm system to protect your home/shop and valuables. Besides, a ready-made Passive Infrared module is integrated with the alarm system for reliable human-motion detection. The built-in passive infrared sensor detects human movement by sensing temperature changes over the scene, and works even in the total darkness . Human body heat moving across the scene will trigger the PIR sensor, and the trigger signal will be sent to the control circuit instantly.
You will be an integral member of the wider EMEA Forensics practice, and help to build Control Risks' reputation in the marketplace through technical excellence, project delivery, networking, and assisting in authoring client facing material. Manual control is also given in this project so the unskilled person can easily change the status. Home automation and Device controlling can be done using Internet of Things – IOT technology. The list of components mentioned here are specifically for controlling 4 different loads. You can change the login password here and program the threshold value for the fire alarm to raise.
The algorithm that is driving the code on the microcontroller is a multi-tasking algorithm. It has three basic functions, first is the main function to read all sensors and actuate the actuators according to the programmed threshold values. Next is the timely updating of the LCD display and the transmission of encoded string serially to the android client if the android client is present. The last task is to check the input serial buffer for commands from the android client and process them accordingly. The ideas related to automation of tasks were in existence during the time of Greeks and after that as well, and during the industrial revolution, automation systems were developed.
These appliances include lights, fans, air conditioners, television sets, security cameras, electronic doors, computer systems, audio/visual equipment, etc. These appliances usually have to be specially designed to be compatible with each other and with the control unit for most commercially available home automation systems. In our day-to-day life, we get used to controlling the home appliances through conventional wall switch boards. But, this conventional home appliance control system is not a convenient method for elders . Thus, the practical example is given above best describes a home automation system which is an Android-based home automation system.
A LINK status pin to the microcontroller from the Bluetooth UART tells it that the android client is successfully connected to the host. Next, to control two light one inside and other outside the home , a fan/AC and a television we have four relays connected to the microcontroller via the NPN transistor based buffer circuit. The relays consume a lot current while being activated and the microcontroller on any pin can source only 20mA of current so a buffer circuit is utmost indispensable between the relay and the controller. Arduino based home automation using Bluetooth project helps the user to control any electronic device using Device Control app on their Android Smartphone. The android app sends commands to the controller – Arduino, through wireless communication, namely, Bluetooth.
The app will be working with the help of Voice Recognition also Internet of Things. The App would be featuring the process of voice recognition that would be taking commands from user in order to control different home appliances that would be connected via IOT. Rapid increase in the number of users of internet over the past decade has made Internet a part and parcel of life, and IoT is the latest and emerging internet technology. Internet of things is a growing network of everyday object from industrial machine to consumer goods that can share information and complete tasks while you are busy with other activities. Smart and secure home using IoT is a system that uses mobile devices to control basic home functions and features automatically through internet from anywhere around the world. It is meant to save the electric power, human energy, and user friendly and a safe system to control home appliances especially aimed to aid the elders.
A Smart phone is a mobile phone based on a mobile operating system, with more advanced computing capability and connectivity than a feature phone. Android is a software stack for mobile devices that includes an operating system, middle- ware and key applications. Android, by simple definition, is an operating system for many mobile phones. Android is a customizable platform that can look and feel very different on every different handsets.
Arduino UNO is chosen due to its capability to perform the both serial and USB features to establish the bluetooth and USB connection to the android application. Light sensor module is chosen because it is the low cost 2-in-1 modules. The voltage regulator is constructed by common reliable regulator circuit which consists of transformer, rectifier and regulator. The system is designed to directly install beside the electrical switches on the wall. The installation of this system eliminates the complex wiring reinstallation and overhead wiring on the wall.
