bluetooth controlled home automation using arduino by shubham sinha
- 3. INDEX • INTRODUCTION TO THE PROJECT • BLOCK DIAGRAM AND CIRCUIT DIAGRAM • HARDWARE REQUIRED • ADVANTAGES • DISADVANTAGES • PROBLEM FACED
- 4. INTRODUCTION 1. To develop a Bluetooth based home automation system with Arduino-UNO Board and an Android application. 2. Remote controlled home automation system provides a simpler solution with Android application technology. 3. Remote operation is achieved by any smart phone/Tablet etc., with Android OS, upon a GUI(Graphical User Interface) based touch screen operation
- 7. HARDWARE REQUIREMENTS •Arduino UNO •Bluetooth Module -HC-05 •12V Relay •Power Supply 230v,50Hz •Switch board
- 8. ARDUINO UNO •The Arduino Uno is a microcontroller board based on the ATmega328P. • It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. • Simply connect it to a Computer with a USB cable or power it with a AC-to-DC adapter or battery to get started
- 9. ARDUINO UNO SPECIFICATIONS •MICROCONTROLLER : ATMEGA 328P •OPERATING VOLTAGE : 5V •DIGITAL I/O PINS : 14 •PWM DIGITAL I/O PINS : 6 •ANALOG INPUT PINS : 6 •FLASH MEMORY : 32KB •CLOCK SPEED : 16MHZ ARDUINO
- 10. BLUETOOTH MODULE Bluetooth Technology is standard for short-range radio communication. It is a low cost bi-directional (2 ways) wireless interface between mobile devices that provides low power consumption. Bluetooth Transceiver referring to Bluetooth Transmitter and Receiver and every Bluetooth node have Bluetooth Transceiver. The aim is to eliminate the usage of cables. Bluetooth system operates in worldwide unlicensed 2.4GHz Industrial-Scientific-Medical (ISM) frequency band. Bluetooth Receiver
- 11. RELAY •Relay is basically an electromagnetic switch which can be turn ON and OFF by applying the voltage across its contacts. •In this project we used a 12V 5 pin relay RELAY
- 12. • The relay takes advantage of the fact that when electricity flows through a coil, it becomes an electromagnet. • The electromagnetic coil attracts a steel plate, which is attached to a switch. • So the switch's motion (ON and OFF) is controlled by the current flowing to the coil, or not, respectively.
- 13. ELECTRICAL WIRE AND JUMPER WIRES Electrical wire is used in the AC power supply and Jumper wire in the DC power Supply. electrical wire jumper wire
- 14. POWER SUPPLY • A device or system that supplies electrical or other types of energy to an output load or group of loads is called a power supply unit or PSU. • Here in our application we need a 9v DC power supply for all electronics involved in the project. • This requires step down transformer, rectifier, voltage regulator, and filter circuit for generation of 9v DC power. • We are using an adaptor here for the power supply
- 15. ADVANTAGES • It is a robust and easy to use system. • It will save your energy and money. • Provides Security. • Convenience and comfort. • Can be used by physically challenged and disabled people. • Complexity is less as only a single mobile is used multiple devices. • Smart home technology.
- 16. DISADVANTAGES • Only works for limited range or short distance with in 5-10m surroundings. • No feedback path. • Number of appliances which can be controlled through this circuit are limited. • Circuit complexity increases as number of devices increase
- 17. PROBLEM FACED DURING THE PROJECT • Problem associated with power supply. We used a step down transformer of 6v but the Arduino was not working properly and also the voltage regulator was not working properly. We overcome that problem by using adapter here • The programming was not easy to compile. • Little problem in wiring of the loads
- 18. FUTURE WORK •This setup can further be developed into IOT project by using Ethernet arduino and a wifi module. •So , it can be controlled from anywhere around the globe having feedback from the devices to further improve the energy savings.
