4. What are IoT devices?

Description:

  • When it comes to IoT, internet is used to send, receive or communicate information. And in each case, the gadget that was connected to the internet wasn’t a computer, tablet or mobile but an object (a thing).
  • They are internet connected devices, hence each of them has a unique IP address and the devices range in complexity from Autonomous vehicle to simple sensors.
  • Any object in the physical world can be transferred into an IoT device if it can be connected to the internet to be controlled or communicate information.
  • IoT devices are generally expected to have an internet connection and that communication with the network independently of human action.


Idea of IoT:

  • Rather than having a small number of very powerful computing devices in life such as laptop, tablet, music player, phone you might have a larger number of devices which are perhaps less powerful such as umbrella, bracelet, mirror, fridge, shoes and water bottles.
  • For this reason, a pc, a smartphone a tablet is not considered as an IoT device whereas a smartwatch or fitness band is considered.

Devices have hardware like sensors that collect data and the collected data is then shared via the cloud and interface with software. The software then analysis and transmits the data to users via an app or website. 

Sometimes these devices communicate with other related devices (M2M communication) and act on the information they get from one another

These devices do most of the work without human intervention, although people can interact with devices for instance, to set them up give them instructions or access the data.

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. Flash memory – 32 KB of which 2 KB used by bootloader. Internal SRAM – 2 KB EEPROM – 1 KB PWM Channels – 6 Power: Mini – B USB Connection 6-20 Unregulated external po...

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 ...
