2. Working Principle of Internet of Things

Consider reservation counters and banks for example:

  • Typical computer system work on the principle, Input-->process-->output.
  • In conventional system input is keyed in by human beings.
  • The software algorithm running at the computing system, process the input data and produces an output.
  • If people responsible are lethargic or lazy, often the speed and accuracy of the system is lost.
  • But in IoT we do not have this issue. Inputs are replaced by relevant sensors.
  • Hence possibility of human error can be eliminated to the great extent. Processing happens in cloud and returned to receiver end.

Block diagram of the process-flow:

  • In many IoT systems, sensors forward data via short-range wireless communication protocols such as Bluetooth, zigbee, wifi to the local computing system. Data gets pro-processed and sent to the central server or the cloud system. Analytics software system takes informed decisions at the cloud platform and will reach the receiver end device. 
  • In few cases this will be an actuator that will execute certain action on the targeted hardware. For E.g: Action could be Opening the door, Switching on the light, Closing the tap. 


IoT system works on the principle:

  • Sensors-->Process-->Acutator similar to Input-->Process-->Output where sensor acts as Input and the Actuator as output.


IoT enabled system consists of :

  1. Sensors
  2. Embedded system
  3. Wireless communication
  4. Data storage via internet into cloud server
  5. Analytics software system to take informed decisions
  6. Receiver end device


Overview:

    We can choose appropriate objects such as lockers, curtains, water bottles, consumer electronic devices such as cookers and interface it with an appropriate sensor, sense the required data and monitor it continuously. At periodic time intervals, data is stored and analysed to take actions. Actions could be a notification in the receiver end device [mobile] or Actuation of some sub-system of the end-device.

7. What is Arduino Nano

The Arduino Nano is a microcontroller.  The Arduino Nano is Arduino’s classic breadboard friendly designed board with smallest dimensions. The Arduino Nano comes with pin headers that allow for an easy attachment onto a breadboard and features a mini-B USB connector. It is an intelligent development board designed for building faster prototypes with the smallest dimension. Oldest member of Nano family. Enough interface for breadboard friendly applications Heart – Atmega328 microcontroller Clocked at a frequency of 16MHZ Same functionalities as the Arduino Duemilanove. 22 digital pins. 8 analog pins. A mini USB port. First embedded micro-controller in the Nano series   Features: High performance low power 8-bit processor. Achieve up to 16 MIPS for MHZ clock frequency.

6.6 LED

Before going into the details of LED (Light Emitting Diode), let us understand electrical transducers and diode.  Electrical Transducer: An electronic device that converts energy from one form to another is called transducer. This process is called transduction. An input transducer takes in physical energy and converts it into an electrical energy. Example: Microphone Takes in physical sound waves and converts into an electrical signal that can be transferred through wires. An output transducer or an actuator takes in electrical signal and converts them into other forms of energy. Example: Lamp  Converts electricity into light.  Motor converts electricity into motion.  This transducer works to convert a form of energy (Heat, light or sound) into an electrical signal (Frequency, current and voltage). DIODE: A diode is a two terminal electric component that conducts electricity primarily in one direction. It has high resistance on one end and low resi...

1. What is 'Internet of Things'?

Description: Internet of things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals, people that are provided with Unique Identifiers (UIDs) and the ability to transfer data over the internet without requiring human-to-human (or) human-to-computer interactions. It is the process of connecting everyday physical objects to the internet.  It refers to a system of physical devices that receive and transfer data over wireless networks with limited human intervention.  It is the concept of computer and machines with sensors which connect to the internet to Report status and Accept control commands. The term 'Thing' in the 'Internet of Things' can be a: Person with heart monitor implant Farm animal with a biochip transponder Automobile that has built in sensor Any other natural or man-made object can be assigned an IP address and is able to transfer data over the internet. Other names of IoT are: Ubiquitous computing Physical ...
