IoT and embedded systems.pptx
- 1. •Basics of IoT •Embedded systems • Sensors and Actuators • Microcontrollers and Applications • Networks, Protocols and MANETs
- 2. Stands for Internet of Things Cannot be fitted in a single definition Simplest explanation :- Internet-of-Things means connection of the simplest things to the internet
- 3. •The term , “Internet of Things”, is used to mean a variety of ideas, depending on the motivation and background of the speaker. •Smart connectivity with existing networks and context-aware computation using network resources is an indispensable part of IoT. •However, for the Internet of Things vision to successfully emerge, the computing paradigm will need to go beyond traditional mobile computing scenarios that use smart phones and portables, and evolve into connecting everyday existing objects and embedding intelligence into our environment. •Network of interconnected objects that not only harvests information from the environment (sensing) and interacts with the physical world (actuation/ command/control), but also uses existing Internet standards to provide services for information transfer, analytics, applications, and communications .
- 6. What is a Refrigerator? An electronic item used to cool and store the daily eatables. It had many problems like :- Forst in the freezer Foul smelling, decayed eatables Storage limits Required temp. according to the weather and food stored & many more All these problems solved with the arrival of the smarter version of the refrigerators Lets see how………
- 7. Processor + Sensors + Network Connectivity + Smart Phone = Smart Refrigerators! It can tell when the water filters are to be refilled, beeps when the door is left open, notify when over weighted, Auto set temperature …………. these are some local intelligence features with applied network connectivity it can:- •Order the essentials by itself •Suggest recipes with the stored ingredients •Weather Forecast
- 9. ANCESTOR CAR MODERN CAR
- 10. It had a simple gearing, steering, electrical and rarest had the stereo systems. They had no rear cameras, cabin controlled petrol locking system and auto locking systems. No GPS, LED headlamps, engine technologies nothing………. The item developed with the time, now it has many electrical features like auto locking, fuel indicators, auto focusing lamps, switch controlled windows, rear gear cameras and many better options like refrigerator, ACs and air bags are provided. The most special and IoT related attractions are auto focusing lamps, Net connected stereos GPS systems and some of the cars are now provided with better braking systems.
- 13. All of your data is on the clouds so it is somehow unsafe and and the chances are higher of it getting leaked. Work becomes impossible if you get disconnected to the network or internet. Commercial sites always have an eye on you. Social isolation Sometimes, companies knowingly or unknowingly sell your data which was expected to be kept safe.
- 15. Different electronic components like capacitors, resistors, chips, etc. when connected together on a single platform to make a useful and productive circuitry becomes an Embedded systems. In case of IoT definition changes a little, An embedded system is one kind of a computer system mainly designed to perform several tasks like to access, process, store and also control the data in various electronics-based systems.
- 16. •Embedded systems are computer based systems that don’t look like computers. •Embedded systems have their own computational complexity. eg cameras , video games. • Sometimes embedded systems don't interact directly with the user, but they interact with the user through another device. Eg flash drives, car braking systems. •the big property of embedded systems and a difference in embedded system design is that efficiency is really important. Embedded System Input Sensors Microcontr ollers Output Actuators
- 18. The computational part inside the embedded system is called as the Microcontroller. A microcontroller is an integrated circuit that executes a program. programs are filled inside the non-volatile memory of the microcontrollers and it executes to them to perform tasks.
- 19. Microprocessor is an IC which has only the CPU inside them i.e. only the processing powers such as Intel’s Pentium 1,2,3,4, core 2 duo, i3, i5 etc. They are general purpose that is can be used to perform different tasks at different times. microprocessor operate above 1GHz as they perform complex tasks. Microcontroller has a CPU, in addition with a fixed amount of RAM, ROM and other peripherals all embedded on a single chip. Microcontrollers are designed to perform specific tasks. Specific means applications where the relationship of input and output are defined. the microcontrollers operate from a few MHz to 30 to 50 MHz,tput is defined.
- 20. Hardware and software components interact with each other to form a perfectly functioning embedded system. For every software instruction executed there should be some output obtained to get the user know about the computation going on. Software programs are executed inside the microcontrollers and the resultant is observed at the hardware components like blinking of the light, vibrations, etc.
- 21. Arduino Uno : A hardware component •Open source platoform for programming. •Used in Washing Machines, radio control cars. •It is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online It works on ATmega328P(datasheet) It has 14 pins power supply, USB connection, reset button, HDMI port.
- 22. When a set of devices gets connected to each other to communicate and carry out tasks they are said to be networked. Devices can be connected by different methods like trans mission lines, wired, RF network and even Internet!
- 23. LAN :- Local area Network PAN:- Personal Area Network MAN:- Metropolitan Area Network WAN:- Wide Area Network
- 25. a protocol, is a set of rules that enables communication which minimally constrains the message. It adds a little bit of data to the message typically. An Internet Protocol, meaning IP or TCP or UDP, provide a naming scheme. Every component on the Internet has to have an IP address, and so each host and router gets assigned at least one of these Internet addresses. A message packet travels through varies machine and networks before reaching its destination. It has 2 parts :- Header and the Payload. Header contains the info about the packet and payload contains the main msg. Internet Protocol(IP) is of 2 types:- Transmission Control Protocol(TCP) User datagram Protocol(UDP)
- 27. Stands for Mobile Ad hoc Network aka Wireless ad hoc network. It has a routable networking environment. Characteristics of MANETs:- • Dynamic topologies • Bandwidth Constrained • Autonomous Behavior • Energy constrained operation • Limited Security • Less Human Intervention
- 28. Mobile Ad hoc Network
Editor's Notes
- #26: Eg. Hello I am ishaan Over hello is the header ishaan is the payload and over becomes the overload. Walky talky cops example!
