I have degitizer, which is communicate data to PC over comport. I am a software developer and need communication with Android over Bluetooth. Yes you may use another bluetooth module with good quality antenna.
A relay is basically a switch which is operated electrically by an electromagnet. A relay can be used to control high voltage electronic devices such as motors as well as low voltageelectronic devicessuch as alight bulbor a fan. Smart home is a term that refers to modern homes that have appliances, Lighting or Electronic devices that can be controlled remotely by the owner, often via a mobile application.

Making India Digital, Tuchware is the fastest growing Indian brand in Digital Locking Industry offers the widest range of smart lock, mortise lock, digital lock. Enjoy flexible management of lighting, heating and cooling ... Improve asset management by continuously monitoring critical equipment.
So that’s how we can create a whole system for the house and can connect all the AC appliances to the 8051 microcontroller using Relays. And this bluetooth controlled home automation system can be operated from a Smart phone. In the circuit, Arduino board, LCD module and LEDs need a 5V regulated DC while relays need 12V regulated DC for their operation. The supply from the battery will be regulated to 5V and 12V using 7805 and 7812 ICs.
Arduino with Channel Relay modules
A home automation system can be controlled via a remote and/or with home computers, and smart phones. Controlling Home Appliances Using Voice - Voice controlled home appliances - This project is designed to control home appliances using a voice-controlled Android application. Imagine that you can control the electronic appliances of your home from anywhere inside the house, just using your Smart phone. In this project, we will use wireless Bluetooth technology to control the Home Electronic Appliances through a Android Phone. Bluetooth has a range of meters, so that you can switch ON and OFF any electronic appliance within the range. We have also developed a Toy car controlled by Android Phone, using Bluetooth module and Arduino.
Can you please provide the circuit to convert from comport to Bluetooth. Your question is already answered above, why are you posting it again and again. Your comment is only visible after getting approved, so you wont be able to see it just after posting.
Step 3: Download Code and Android App
The Bluetooth module has six pins – Enable, VCC, Ground, Transmit Data , Receive Data and State. The Enable and State pin are unused and so not connected in the circuit. The VCC and Ground pins are connected to the common VCC and Ground. The TxD and RxD pins of the module are connected to the pins 10 and 11 of the Arduino. Configure the pins connected with the bulbs and the TX pin as output pins and the RX pin as an input pin.
A Bluetooth based wireless home automation system can be implement with a low cost and it is easy to install in an existing home. A research work proved that Bluetooth system are faster than wireless and GSM systems. Bluetooth technology has ability to transmit data serially up to 3 Mbps within a physical range of 10m to 100m depending on the type of Blue tooth device. The design of proposed method is based on Arduino board, Bluetooth module, sensors and smartphone application.
Circuit Diagram and Explanation
In our case, the pins are 8, 9, 10, 11, 12, and 13 respectively. One end of 220VAC to all common terminals of relay and other ends with other terminals of the light lamps. Connect one end of all bulbs to the normally open terminal of relays.
HC-05 Bluetooth module consists two things one is Bluetooth serial interface module and a Bluetooth adaptor. Bluetooth serial module is used for converting serial port to Bluetooth. Keywords- Home automation; Smartphone; Arduino; Bluetooth; Home appliances. The diagram shows the pin configuration of a 16×2 LCD display.
Bluetooth module HC-05 is interfaced with Arduino board and home appliances are connected with Arduino board via relay. Smartphone application is used for serial communication between smartphone and Bluetooth module which is further connected with Arduino board. Several remote controlled home automation systems have been studied. R.Piyare and M.Tazil research work provided full functionality to remotely control home appliances via wireless communication between the Arduino BT and cell phone using Bluetooth technology. Arduino BT board was connected with home appliance and it was controlled by a Symbian OS cell phone application.
Provides for an environment with multiple wireless systems to perform a given task using a ... 5.Bluetooth Module • HC-05 is a Bluetooth Smart module targeted for low-power sensors and accessories. • It integrates all features required for a Bluetooth Smart application. • It is powered directly from a standard 3V coin cell battery or a voltage regulator. • In the lowest power sleep mode it merely consumes 500 nA and will wake up within a few hundred microseconds. Sir , please provide the code with LCD interface also the modified circuit diagram.
Similarly, another study presented home automation system using Bluetooth and android application. However, this was designed only for 4 lights and it was not feasible to control more than 4 Home appliances. In another research work, XBee based home automation system introduced for handicapped and elderly people. XBee transceivers was used for wireless communication between the master control panel board and the remote control device. The 12V 2A relays are used to switch the AC appliances ON or OFF in the project.
Embedded computing devices integrate SoM to control, monitor, and perform a specific function by executing commands. Microprocessors and microcontrollers integrated on these modules are the basic components used to operate embedded computing systems. These are used in various applications including office automation, home applications, banking & financial institutes, security, defense, healthcare, and automobile, among others. They offer additional features such as low power consumption, enhanced accuracy, increased reliability & adaptability, and high speed, accelerating market growth.
