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.

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 ...

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...

6.5 Capacitor and Capacitance

  Description:  Capacitance is the capacity or ability of a capacitor to store electrical energy. Capacitor is a component to store and discharge energy. The other name for capacitor is condenser. Image shows different variants of Capacitor Working: The capacitor is made up of two close conductors (usually plates) that are separated by a dielectric material. The plates accumulate electric charge when connected to power source. Once the battery is connected, negative charges on the right side gets attracted towards the positive terminal of the battery and on the left side, negative charges gets repelled away from the negative terminal of the battery. As the negative charges leaves the piece of metal in the right, it makes that piece of metal positively charged, and the piece on left becomes negatively charged. Both sides has same magnitude of charge. As the plate on the right becomes positively charged, the next electron gets confused where to move, whether to the positive term...
