We have already seen how a DTMF controlled home appliances system works in the earlier post. Operating conventional wall switches is difficult for physically handicapped or elder people. This project provides the solution to this problem by integrating all the electrical appliances to a control unit that can be operated by an Android application on a device (Android smart phone or Tablet). The proposed system controls the electrical loads based on the data transmitted by the Android device. An Android application should be installed in user’s mobile or tablet to control the electrical loads. Using this Android application user can send the commands to the Bluetooth module to control the electrical loads. Wireless technology used in this project is Bluetooth. It can also be called as “Bluetooth Controlled Electronic Home Appliances” or “Android based Home Automation System” or “Remote Password Operated Electronic Home Appliances Control System”. [Also Read: How To Make an Adjustable Timer ] . Bluetooth Controlled Electronic Home Appliances Circuit . This Bluetooth Module receives the commands from the Android application that is installed on the Android device. Microcontroller switches the electrical loads automatically based on the commands received from the Bluetooth. Android Based Home Automation System Circuit Block Diagram Bluetooth Controlled Electronic Home Appliances Circuit Diagram Components Required Hardware Requirements 8051 Microcontroller (AT89C51) 8051 Development Board 8051 Programmer (Programming Board) Programming Cable 16 × 2 LCD Display 10KΩ Potentiometer . using wireless communication (Bluetooth Technology).Principle In this project. a Bluetooth module is interfaced to 8051 Microcontroller. The program which is written to the 8051 microcontroller communicates with Bluetooth module serially to receive the commands. Here. GND and P3. It is an 8 – bit microcontroller and it requires supply voltage of 5V DC. then you can build the 1 – channel relay circuit (for 1 load) using the following 5V or 12V Relay BC547 NPN Transistor 1N4007 PN Junction Diode 1 KΩ Resistor (1/4 Watt) Software Requirements Keil µVision IDE Willar Software Proteus (for Circuit Diagram and Simulation) Android Application installed on Android Device Buy Step by step Guide along with Code:Bluetooth Controlled Electronic Home Appliances» Android Based Home Automation System Circuit Design This project consists of a microcontroller. Loads (Light Bulbs are used in the demonstration) and Bluetooth Module. Crystal Circuit and Reset Circuit) if you are using an 8051 Development Board.7 pins respectively. the LCD display is used to indicate the status of electrical loads and also used to display received data from Bluetooth (Optional Feature).6. 16 x 2 alphanumeric LCD. For the above circuit additionally you need to connect reset circuit and crystal circuit to the controller to work properly. the LCD Display is interfaced to the PORT1 of the microcontroller in 8 – bit mode i. We can use 9V DC battery or 12V. You can ignore these connections (Power Supply Regulator. 1A adapter to provide the supply to the circuit. .) Power Supply Connecting wires If 8051 Development Board isn’t available. a 10KΩ POT is connected to the Contrast Adjust pin of the LCD to control the contrast of the display. Bluetooth Module (HC – 05) 4 – Channel Relay Module Loads (like Light Bulb. etc. RS. then you might need the following 10µF Electrolytic Capacitor 2 x 10KΩ Resistors (1/4 Watt) 2 x 33pF Ceramic Disc Capacitors 0592 MHz Quartz Crystal Push Button 1KΩ x 8 Resistor Pack If Relay Module isn’t available. Also. the data pins of the LCD are connected to PORT1.e. The three control pins of the LCD i. AT89C51 Microcontroller is used. 4 – Channel Relay Module. In the above circuit. Here. Fan. Use 7805 power supply circuit to provide 5V DC to the microcontroller.e. RW and EN are connected to P3. To know about all the Bluetooth AT commands refer HC-03/05 Embedded Bluetooth Serial Communication Module AT command set. Electrical loads (like Lamp and DC motor) are connected to the P0. AT+PSWD =<password> — Sets module pairing password. Use a baud rate of 9600 to communicate with Bluetooth. 4. Display the received data on LCD. Display the status of electrical loads on LCD. Android based Home Automation System Circuit Simulation Video Watch the following output video of home automation system using android applications.0 to P0. VCC pin (Pin 40) is connected to the +5V and GND pin (Pin 20) is connected to ground. NOTE: The Circuit Diagram shows connections of only one load.1) of the microcontroller. Below are the few Bluetooth AT commands: AT — Responds OK. The Microcontroller communicates with Bluetooth Module using serial communication (UART protocol). If you are using a relay module. Algorithm for Bluetooth Controlled Electronic Home Appliances 1. Compare the received string with predefined strings and accordingly switch the electrical loads. 5. AT+PSWD? — Responds with the existing password. (Used to test the Bluetooth module) AT+RESET — Responds OK. AT+NAME = <name> — Responds OK.3 Pins through the 4 – Channel Relay Module. NPN transistors are used to drive the relays. . (Used to reset the module) AT+NAME? — Responds with the module name. But the connections to the other loads can also be made in a similar fashion. 2. relays are used to switch AC loads using small DC voltages. then transistor and other important components to drive the relay are already embedded on the module itself. Now read the data from Bluetooth module. Name should be less than or equal to 20 characters. Here.0 and P3. 3. If you want to change the Bluetooth name and password then you need to use Bluetooth AT commands. Initialize the LCD and UART protocol.The TX and RX Pins of the Bluetooth Module are connected to the RXD and TXD pins (P3. 3. give the connections as per the circuit diagram. Install the “Bluetooth Controller” application on your Android Device (Mobile Phone or Tablet) from the following link https://play. 5. Now pair the Android device with Bluetooth module. Switch on the both AC and DC supplies. Bluetooth Controlled Electronic Home Appliances Project Output Video . 8.com/store/apps/details? id=apps. 6. While making the connections. Write the program to the project in Keil software and create .BT&hl=en 9.google. Configure the Bluetooth Controller App as per the 8051 Program. Burn program to the controller with help of 8051 Programmer and Willar Software. Use 5V power supply circuit to provide regulated 5V DC to the microcontroller. ensure that there is no any common connection between DC and AC supplies.hex file. 4. So. Now relay output pins gets 230V. Now. 7. “ Related Post: Also read the post – RF remote control for Home Appliances.
