  • Best survey site online! $1,500 a month thanks to you guys! Without a doubt the best paid surveys site online!I have made money from other survey sites but made double or triple with GoldOpinions.com for the same time and effort. The variety and number of daily paid surveys I get from them is unmatched. A must for anyone looking for extra cash or a full time income. ▲▲▲ http://t.cn/AieXAuZz

IoT BASED SMART HOME USING ARDUINO

  1. 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. 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. 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. 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. 5. ALTERNATE SOLUTION • ZIGBEE BASED • BLUETOOTH BASED • GSM BASED • But our project is wireless home automation system using IoT.
  6. 6. BLOCK DIAGRAM
  7. 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. 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.
  9. 9. GANTT CHART 1 2 3 4 5 6 7 8 9 10 11 FINAL PROJECT GANTT CHART ACTIVITIES Concept Product finalization Basic design Final design hardware Packing SUBMISSION PHASE Review IMPLEMENTATION PHASE 2 Loading program to IC Hardware on bread board Testing 1 IMPLEMENTATION PHASE3 Pcb design Body design Final software design Product procurement IMPLEMENTATION PHASE 1 Programs Power supply Simulation of circuit Hardware on bread board Final report Package design IMPLEMENTATION PHASE 4 Pcb making Soldering Testing 2
  10. 10. COMPONENTS REQUIRED HARDWARE • ARDUINO MEGA • LDR • PIR • DHT11 • HCSR04 • SOIL MOISTURE SENSOR • ESP8266
  11. 11. SOFTWARE • ARDUINO IDE-C/C++ • ANDROID STUDIO-JAVA • FRITZING
  12. 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. 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. 14. ARDUINO MEGA
  15. 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. 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
  17. 17. LDR • Used to sense light • Photocell is used • Resistance is inversely proportional to light falling on it. • Lightly doped for required conductivity
  18. 18. 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
  19. 19. 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
  20. 20. 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(
  21. 21. DHT11 • Humidity+Temperature sensor • Measurement range: 20-90%RH,0-50’C • Sends data in form of pulses train of specific time period.
  22. 22. ESP8266
  23. 23. • 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.
  24. 24. 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
  25. 25. ADVANTAGES • Adding Convenience to your Daily Life. • Energy efficient • Customization • Ease of Use • Save Money and the Environment • Security
  26. 26. DISADVANTAGES • Equipment and installation costs • System crashes due to any damage in the interconnection • Reliability • Difficult to control different sensors simultaneously.
  27. 27. 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.
