- 3. What is IoT ? The Internet of Things (Iot) is the network of physical objects or things embedded with electronics software, sensors , and network connectivity , which enables these objects to collect and exchange data.
- 4. • A “Thing” in the context of Internet of Things (IoT), is an entity or physical object that has the ability to transfer data over a network. • Smart microwaves • Self driving cars with built in sensors • Wearable fitness devices that measure your heart rates etc. • These devices collect useful data with the help of various existing technologies and then autonomously flow the data between other devices.
- 5. History of IoT In 1999 Kevin Aston, also known as the father of Iot coin the term “Internet of Things” and establishes MIT’s Auto-ID Center, a global research network of academic Laboratories focused on the IoT. He believed that “Information is a great way to reduce waste and increase efficiency, and that’s what the Internet of Things provides”.
- 6. How IoT Works ? The Internet of Things(IoT) , consists of all the web- enabled devices that collect, send and act on data they accuire from their surrounding environments using embedded sensors, processors and communication hardware.These devices communicate with each other and act on the information they get from one another. Humans can give instructions or access data, but the devices do most of the work on their own without human intervention.
- 7. The Internet of Things Lifecycle COLLECT (Devices and Sensors collect data like at your house , in your car etc.) COMMUNICATE (Sending data and events through networks to a cloud platform) ANALYSE (Creating information from the data like building report filtering data) ACT (Taking action based on the information and data like talk to another system or sending notification)
- 8. Few Applications of IoT • Building and Home automation
- 9. • Medical and Healthcare systems
- 10. • Transportation
- 11. • Environment monitoring • Manufacturing • Energy management • Infrastucture management • Media and so on.
- 12. Electronic Platforms for IoT 1. ARDUINO
- 13. • Arduino is an open-source prototyping platform based on easy-to-use hardware and software IDE. Arduino boards are able to read inputs like light on a sensor and turn it into an output,activating a motor, turning on an LED. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. It is like the brain of a project. • The programming languages that are used with arduino board are C and C++.
- 14. Why Arduino ? • Inexpensive • Cross-platform • Simple programming environment • Open source and extensible software • Open source and extensible hardware
- 16. • Power USB - Arduino can be powered by using the USB cable from computer. • Crystal Oscillator - It helps arduino in dealing with time issues. • Power LED indicator – This LED should light up when you plug your Arduino into a power source. • Pins - Arduino UNO R3 microcontroller based on Atmega328p has 14 digital pins of which 6 can be used as PWM outputs, 6 analog inputs, a USB connection , power jack , ICSP header and a reset button.
- 17. 2. RASPBERRY Pi
- 18. • The Raspberry Pi is a credit sized fully featured micro-computer squashed onto a circuit board measuring approximately 9cm x 5.5cm. • By default it supports Python as programming language but any language which will compile for ARMv6 can be used with the raspberry Pi. • The SoC used in Raspberry Pi is Broadcom BCM2835 SoC. • It does not include a built-in hard disk , but uses an SD card for booting and long-term storage. • Supports and runs on free and open source Linux OS
- 19. Why Raspberry Pi ? • Low cost • Works on low power • Small in size and portability • It works as a Low cost server to handle web traffic • Can work with open source operating systems like ArchLinux ARM, Respbian , Fedora etc. • Easy to program
- 21. • Memory (RAM) - 512 Mb • Processor – Broadcom BCM2835 SoC • GPU - Broadcom Videocore IV • USB 2.0 – 4 ports • On board storage - micro SD card • Video input - Camera support via CSI connector • Video Output – HDMI support via DSI • Networking - Ethernet support • Audio Output – 3.5mm jack • GPIO pins - 40 General Purpose Input Output pins
- 23. OBJECTIVE The main objective of the project is to provide a platform that monitors the parameters and help to create better and pollution free future life.
- 24. Hardware Requirements • Arduino Atmega 328P Microcontroller • DHT22 Module • MQ135 Gas Sensor • Soil Moisture Sensor • 16*2 Liquid Crystal Display (LCD) • ESP 8266 WIFI Module • PCB Board • Light Detecting Resistors (LDR) • Resistors • Jumper Wires • Soldering Kit • 12v Supply • I2c (Inter integrated Circuit) Module for LCD Interfacing in TWI Mode
- 25. DHT22 Module The DHTxx sensors have four pins, VCC, GND, data pin and a not connected pin which has no usage. A pull-up resistor from 5K to 10K Ohms is required to keep the data line high and to enable the communication between the sensor and the Arduino Board.
- 26. MQ – 135 Gas Sensors Used in air quality control equipment for buildings/offices, is suitable for detecting of NH3, NOx, alcohol, Benzene, smoke, CO2, etc.
- 27. Soil Moisture Sensor This sensor measures the volumetric content of water inside the soil and gives us the moisture level as output.
- 28. Light Dependent Resistors (LDR) An LDR is a transducer which changes its resistance when LIGHT falls on its surface changes.
- 29. CONCLUSION The proposed system which is designed shows the simulation output of sensing the carbon dioxide gas in air, humidity, noise pollution and temperature pollution in Environment. The sensor output is pushed to cloud and can be viewed through internet. This is a flourishing system which is very useful in industries because of the increasing pollution due to increase in industries. This system is user friendly. The results of the project are accurate and hence can be implemented in any industries for the safety of workers and the environment.
