Android remote control based home automation consists of Android OS operated Graphical User Interface with wireless communication modules such as Bluetooth and Zigbee to have control on different home appliances. In this circuit diagram AT89c52 microcontroller is used which consist of CPU, RAM, ROM, timers and input, outputs ports .It is just like a computer only difference is the memory and also no need to use any microprocessor to make any function. The AT89c52 is low power, high performance 8 bit microcontroller with 8k bytes programmable flash memory. The device is manufactured using Atmel high-density nonvolatile memory technology and is compatible with the industry standard 80c51 instruction set pin output.
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.

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.
The below figure shows the structure of home-control systems where different sensors corresponding to the home appliances with the appropriate actuators are hard-wired to input/output modules of a central controller. The sensors sense the motion, light, temperature, smoke and other sensing variables using sensing devices like photo detectors, IR sensors, thermocouples, current and voltage transformers, etc. Upon receiving these variables and based on the program, the main or central controller actuates the loads using actuators like motors, switches, relays, and other actuating devices. In this block diagram microcontroller is programmed in C language and used to turn on and off the appliances, which are connected through relays, when we send the commands through Bluetooth from a mobile phone. A feedback circuit is also designed and implement to check the current status of the device after it receives the command from mobile phone. The communication is done one by one at one time in both direction between the android mobile phone and Bluetooth module.

With the 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. Wireless Home Automation system using IoT is a system that uses computers or mobile devices to control basic home functions and features automatically through internet from anywhere around the world, an automated home is sometimes called a smart home.
This is because here we are operating pre digital circuitry that fails to operate on unregulated and unfiltered supply. After the DC supply is being filtered as it is unregulated is turned into a regulated 5V DC supply using LM7805 regulator. Again after that a small 100nF capacitor is there to filter the regulated DC supply. A regulated 3.3 volt supply is also derived from another regulator that is the UA78M33 whose input is fed from the regulated 5V output of the LM7805 voltage regulator. Regulated 5 volt supply is needed to drive the microcontroller, relays and all the sensors, while a regulated 3.3 volt is required by the Bluetooth UART module to operate.
Smart Home Lighting Control Systems
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.
The home automation system is nothing but a term used to describe the working of all household appliances. Smart Home Automation let the user to control the home from his or her phone and assign actions that should happen depending on time or other sensor readings such as light, temperature or sound from any device in the Home Automation network. Figure-7 illustrates the interface of Android GUI selecting bluetooth device.

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.
An embedded board physically connected all home automation devices and through integration with a personal computer based web server, provided remote access to the system .This paper presents smart house controlled by various micro controller systems. The third sub-system is lighting control system which includes the internal house lighting, and the ceil lighting outside the house. The fourth sub-system is the remote control system for house controlling.
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.
FIG 1 This screen displays a boot animation on startup when you click the Smarthome application icon. Along with the animation, an audio message and welcome can be heared in the background. The transmission and reception of commands to and from the android client is done wholesomely in ASCII code.
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.
This project can provide the facility of monitoring all the appliances with in the communication range through Bluetooth. But after login, it only displays the main screen of turning on and off the appliances. The settings option does not appear where i can connect to the bluetooth. Basic4android language is similar to Visual Basic language with additional support for objects.Basic4android compiled applications are native Android applications, there are no extra runtimes or dependencies. Unlike other IDEs Basic4android is 100% focused on Android development. Basic4android includes a powerful GUI designer with built-in support for multiple screens and orientations.
The server can also receive connections over the internet and can be controlled from a remote location. For example, one could remotely turn on the air conditioner from the office before leaving so that the room is cool before reaching home. Home automation can range in complexity from the simple gadgets and gizmos that provide control over individual components to individual home sub-systems and integrated whole house systems.
