Small Discussion About IOT?

What is IOT?

The Internet of things (IoT) is the network of physical devices, vehicles, and other items embedded with electronics, software, sensors, actuators, and network connectivity which enable these objects to collect and exchange data

The IoT allows objects to be sensed or controlled remotely across existing network infrastructure, creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency, accuracy and economic benefit in addition to reduced human intervention. When IoT is augmented with sensors and actuators, the technology becomes an instance of the more general class of cyber-physical systems, which also encompasses technologies such as smart grids, virtual power plants, smart homes, intelligent transportation and smart cities

A thing, in the Internet of Things, can be a person with a heart monitor implant, a farm animal with a biochip transponder, an automobile that has built-in sensors to alert the driver when tire pressure is low -- or any other natural or man-made object that can be assigned an IP address and provided with the ability to transfer data over a network. 

IoT has evolved from the convergence of wireless technologies, micro-electromechanical systems (MEMS), microservices and the internet. The convergence has helped tear down the silo walls between operational technology (OT) and information technology (IT), allowing unstructured machine-generated data to be analyzed for insights that will drive improvements.

IOT Platform

The IoT platform is a suite of components that enable: Deployment of applications that monitor, manage, and control connected devices. Remote data collection from connected devices. Independent and secure connectivity between devices. Device/sensor management.

An IoT platform is also often referred to as IoT middleware, which underlines its functional role as that of a mediator between the hardware and application layers. The best IoT platforms are capable of being integrated with almost any connected device and blend in with the applications used by the device. This independence from underlying hardware and overhanging software allows a single IoT platform to implement IoT features into any kind of connected device in the same straightforward way.

What is ThingsBoard?

ThingsBoard is an open-source server-side platform that allows you to monitor and control your IoT devices.

With ThingsBoard, you are able to:

  • Provision and control devices.
  • Collect and visualize data from devices.
  • Analyze device data and trigger alarms.
  • Deliver device data to other systems.
  • Enable use-case specific features using customizable rules and plugins.

Features

  • scalable: horizontally scalable platform, build using leading open-source technologies.
  • fault-tolerant: no single-point-of-failure, every node in the cluster is identical.
  • robust and efficient: single server node can handle tens or even hundreds thousands of devices depending on use-case. ThingsBoard cluster can handle millions of devices.
  • customizable: adding new functionality is easy with customizable widgets, rule engine, and plugin system.
  • durable: never lose your data.

The ThingsBoard IoT Gateway is an open-source solution that allows you to integrate IoT devices connected to legacy and third-party systems with ThingsBoard.

ThingsBoard IoT Gateway provides following features:

  • MQTT extension to control, configure and collect data from IoT devices that are connected to external MQTT brokers using existing protocols.
  • OPC-UA extension to collect data from IoT devices that are connected to OPC-UA servers.
  • Sigfox extension to collect data from IoT devices that are connected to Sigfox Backend.
  • Persistence of collected data to guarantee data delivery in case of network and hardware failures.
  • Automatic reconnect to ThingsBoard cluster.
  • Simple yet powerful mapping of incoming data and messages to unified format.

What is Raspberry Pi?

The Raspberry Pi is a credit-card-sized computer that plugs into your TV and a keyboard. It is a capable little computer which can be used in electronics projects, and for many of the things that your desktop PC does, like spreadsheets, word processing, browsing the internet, and playing games.

The Raspberry Pi is a series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation to promote the teaching of basic computer science in schools and in developing countries.The original model became far more popular than anticipated, selling outside of its target market for uses such as robotics. Peripherals (including keyboards, mice and cases) are not included with the Raspberry Pi. Some accessories however have been included in several official and unofficial bundles.

The Raspberry Pi is slower than a modern laptop or desktop but is still a complete Linux computer and can provide all the expected abilities that implies, at a low-power consumption level.

The Raspberry Pi is open hardware, with the exception of the primary chip on the Raspberry Pi, the Broadcomm SoC (System on a Chip), which runs many of the main components of the board–CPU, graphics, memory, the USB controller, etc. Many of the projects made with a Raspberry Pi are open and well-documented as well and are things you can build and modify yourself.
