- 2. INTRODUCTION It realizes the concept of a smart home. Makes a wireless home network. Appliances can communicate with each other in network. Used in a cost-effective manner. Provide secured network.
- 3. ADVANTAGES • The main advantage of this is that it’s Wireless. All you need is a smartphone to control. • Replace television, air conditioner, remotes etc. • It’s efficient and cost effective. • It helps to make a Smart Home.
- 4. APPLICATIONS • Home automation – This project can be used to control various Home Appliances. • We can control device from a long distance, thus it gives ease of access. • Faster operation and efficient. • No need to carry separate remote or any other controlling unit.
- 5. COMPONENTS USED Arduino Uno. 8 channels relay module (5v/12v) adapter. HC-05 Bluetooth module. Jumper wires male to female, male to male. AC (220v/120v) Loads/Home appliances. Laptop/PC. Android phone. Arduino IDE (used for programming the Arduino Uno). Control app with Arduino code (be installed on the smartphone to control the appliances).
- 8. ARDUINO UNO
- 9. ARDUINO UNO • Arduino is an open source electronics prototyping platform based on flexible, easy- to-use hardware and software. It is intended for artists, designers, hobbyists and anyone interested in creating interactive objects or environments Arduino Uno is based on ATmega328 microcontroller (MCU). It consists of 14 digital input/output pins, six analogue inputs, a USB connection for programming the onboard MCU, a power jack, an ICSP header and a reset button. It is operated with a 16MHz crystal oscillator and contains everything needed to support the MCU. It is very easy to use as you
- 11. BLUETOOTH MODULE (HC-05) • Bluetooth module used in this project is HC-05 (Fig. 4), which supports master and slave mode serial communication (9600-115200 bps) SPP and UART interface. Using these features it can communicate with other Bluetooth-enabled devices like mobile phones, tablets and laptops. The module runs on 3.3V to 5V power supply. It has got 6 pins.
- 12. RELAY MODULE
- 13. RELAY MODULE • A relay allows you to turn on or turn off a circuit using voltage and/or current much higher than what Arduino could • handle. Relay provides complete isolation between the low-voltage circuit on Arduino side and the high-voltage side • controlling the load. For this project a 4 channel, 5V relay channel has been taken. This 5V 4- channel relay interface • board and each channel needs a 15-20mA driver current. It can be used to control various appliances and equipment • with large current. It is equipped with high-current relays that work under AC250V 10A or DC30V 10A. It has a • standard interface that can be controlled directly by microcontroller.
- 14. SOFTWARE ARDUINO SOFTWARE (IDE) • The open-source Arduino Software (IDE) makes it easy to write code and upload it to the board. It runs on Windows, • Mac OS X, and Linux. The environment is written in Java and based on Processing and other open-source software. This software can be used with any Arduino board.
- 15. ANDROID APP • An android app is used to control the appliances wirelessly. We’ve developed an app for wireless commands.
