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.
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.
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.
Macchina is an open source software toolkit for quickly building embedded applications for the Internet of Things that run on Linux-based IoT gateways and devices like the Raspberry Pi, Beaglebone, RED Brick or Galileo/Edison.
Runs on Embedded Linux devices with as little as 32 MB of RAM, as well as desktop Linux and OS X. Develop and test on desktop machine, then easily deploy to embedded device.
It runs on Linux-based devices, including IoT gateways, industrial computing devices, and prototyping platforms like the Raspberry Pi, Beaglebone and MangOH.
Zetta is an open source platform built on Node.js for creating Internet of Things servers that run across geo-distributed computers and the cloud. Zetta combines REST APIs, WebSockets and reactive programming – perfect for assembling many devices into data-intensive, real-time applications.
npm install zetta
Zetta servers run in the cloud, on PCs and on single-board computers. With Zetta you can link Raspberry Pis, BeagleBones and PCs together with cloud platforms like Heroku to create geo-distributed networks.Zetta turns any device into an API.
Zetta servers communicate with microcontrollers like Arduino and Spark Core giving every device a REST API both locally and in the cloud.
Zetta's reactive hypermedia design marries reactive programming with Siren hypermedia APIs so that you can assemble distributed systems of devices that communicate and react via APIs.
Building Internet of Things systems is complex. Zetta provides helpful abstractions for increased developer productivity while also giving direct access to underlying protocols and conventions allowing you to focus on the big picture without losing track of the details so that you joyfully transform sensors, actuators and controllers into big, creative applications.
Zetta's architecture is optimized for data-intensive, real-time applications. Zetta allows you to observe and react to device and system behavior in code and using visualization tools
