IoT BASED SMART HOME USING ARDUINO
- 1. SMART ENVIORNMENT USING IoT PRESENTED BY COORDINATED BY GUIDED BY AKSHARASASIDHARAN KRISHNA RAJ SENTHIL NIVAS ARDRA MS AYSHA S KABEER NEETHU A COLLEGE OF ENGINEERING,KOTTARAKKARA
- 2. PROJECT IDEA • Design and construct a home automation system that can be control automatically and manually using IoT. • The status of each appliances can be view in android app.
- 3. INTERNET OF THINGS • Inter networking of physical devices, vehicles, buildings and other items. • Embedded with electronics, software, sensors • Internet connected objects working together to solve a problem.
- 4. WHY IoT ?? • Generate, collect, process and use acquired information to make better decisions. • Things could be anything. Physical or virtual. • Things can be interact each other smartly. • Create a social network of sensors
- 5. ALTERNATE SOLUTION • ZIGBEE BASED • BLUETOOTH BASED • GSM BASED • But our project is wireless home automation system using IoT.
- 7. BLOCK DIAGRAM DESCRIPTION • Transformer, rectifier and regulator is used to provide power supply • Light is sensed by using LDR and control the lamp through relay • Motion is detected by using PIR and security is provided by making alarm through buzzer. • Temperature & humidity can be sensed and can be used to control fan using DHT11..
- 8. • Water level in tanks or even having a check on floods can be done using ultrasonic sensor. • Plant watering is made simpler in this project by measuring moisture content on soil and watering accordingly.

- 10. COMPONENTS REQUIRED HARDWARE • ARDUINO MEGA • LDR • PIR • DHT11 • HCSR04 • SOIL MOISTURE SENSOR • ESP8266
- 11. SOFTWARE • ARDUINO IDE-C/C++ • ANDROID STUDIO-JAVA • FRITZING
- 12. WHY ARDUINO ?? • Simplicity – easy to interface & simple coding • Robustness – turn on and off at any time, there is no shutdown of operating system • Low power consumption - easily powered from battery • Cheaper • Suitable for electronic products
- 13. ARDUINO • Microcontroller based physical computing platform. • Does not need any OS • Need to create sketch in the arduino language(just like C) • Inbuilt ADC.
- 14. ARDUINO MEGA
- 15. FEATURES • Microcontroller ATmega2560 • Operating Voltage 5V • Input Voltage (recommended) 7-12V • Input Voltage (limits) 6-20V • Digital I/O Pins 54 (of which 15 provide PWM output) • Analog Input Pins 16
- 16. • DC Current per I/O Pin 40 mA • DC Current for 3.3V Pin 50 mA • Flash Memory 128 KB of which 4 KB used by bootloader • SRAM 8 KB • EEPROM 4 KB • Clock Speed 16 MHz
- 18. LDR • Used to sense light • Photocell is used • Resistance is inversely proportional to light falling on it. • Lightly doped for required conductivity
- 19. SOIL MOISTURE SENSOR • When soil having water shortage, the sensor o/p will be high. Otherwise low. • Triple output mode. Digital o/p, analog o/p and serial o/p • Adjustable sensitivity
- 20. HCSR04 • Provides 2cm-4m non contact measurement. • Module include transmitter, receiver and control circuit. • Test distance=(high level time*velocity of sound)/2. • Plane should be smooth for accurate measuring
- 21. PIR • Used for motion detection • Passive infrared sensor • 3pins- gnd, vcc, o/p • o/p pin will be high when motion detected • Sensitivity 20 feet range(
- 22. DHT11 • Humidity+Temperature sensor • Measurement range: 20-90%RH,0-50’C • Sends data in form of pulses train of specific time period.
- 23. ESP8266
- 24. • Self contained SOC with integrated TCP/IP protocol. • 1mb flash memory. • Integrated TR switch, balun, LNA, power amplifier and matching network. • Integrated PLL, regulators, and power management units.
- 25. APPLICATIONS • Precise and safe blind control • Security cameras can be controlled • User can observe and control the activities. • Detect any kind of unauthorised movement and notify the user through security system
- 26. ADVANTAGES • Adding Convenience to your Daily Life. • Energy efficient • Customization • Ease of Use • Save Money and the Environment • Security
- 27. DISADVANTAGES • Equipment and installation costs • System crashes due to any damage in the interconnection • Reliability • Difficult to control different sensors simultaneously.
- 28. CONCLUSION • This is an on going project and our prime objective is to assist handicapped/old aged people. • This paper gives basic idea about the controlling of home appliances and provide a security using android. • In future it can be expanded to many other areas.
