5 Data Models for IoT

Apache Cassandra is a rock-solid choice for managing IoT and time series data at scale. The most popular use case of storing, querying, and analyzing time series generated by IoT devices in Cassandra is well-understood and documented. In general, a time series is stored and queried based on its source IoT device. However, there exists another class of IoT applications that require quick access to the most recent data generated by a collection of IoT devices based on a known state. The question that such applications need to answer is: Which IoT devices or sensors are currently reporting a specific state? In this blog post, we focus on this question and provide five possible data modeling solutions to efficiently answer it in Cassandra.

Introduction

The Internet of Things (IoT) is generating massive amounts of time series data that needs to be stored, queried, and analyzed. Apache Cassandra is an excellent choice for this task: not only because of its speed, reliability, and scalability but also because its internal data model has built-in support for time-ordered data.

A Camunda Greenhouse: Part 3

Review

If you've been following this (incredibly slow) project, then you've already been through part 1 and part 2 and have been wondering if part 3 would ever arrive. Well, here it is! This is the part where I pull together all the previous parts and actually deploy a Camunda BPMN-powered IoT Greenhouse!

Just to review a bit, I proposed building a greenhouse, monitored by some IoT sensors, that would then be entirely controlled by a Camunda BPMN process. The entire process would then control all aspects of the Greenhouse.

Build Your IoT Application in a Day

IoT Application development is required today at all levels. But for people with very low coding knowledge, it is not easy to build/develop what is needed for them. With MQTTRoute, an IoT application framework with an inbuilt MQTT Broker, any early adopters or budding developers can develop, host and manage their application easily. This just leaves their development challenge for their IoT Server application. MQTT Broker comes with a default user interface, however, visualization needs to be built specific for each distinct vertical. We recently run an internal hackathon at Bevywise to build applications over our framework. Interestingly, we were able to build an IoT application in a day. The application built was an Industrial Furnace Monitoring. This blog portrays the hacks used to build the application.

IoT Application for Industrial Temperature Monitoring

Monitoring and control of the temperature of the furnaces is crucial with respect to its usage in the industries as it directly affects the quality of the product that is being created. We have created a simulated device using IoT Simulator similar to a monitoring edge device that pushes data to the MQTT Broker. The goals set for the application were:

Top IoT App Development Trends in 2021

More Focus on Container Technologies in IoT Platforms

Gartner projects that over 75% of global organizations will be using containerized apps in production by 2022. So far, container technologies have been part of traditional enterprise IT environments and cloud architectures. Recent developments in industrial IoT platforms and the increased demand for vendor-neutral IoT technologies, however, have made containers increasingly relevant for the Internet of Things. 

Defining Containers

What is a container? It is a lightweight virtualization technology that includes an entire runtime environment. This means an application and all its dependencies, plus the libraries and configuration files required to run the application. Container technologies help you abstract differences in operating systems and underlying infrastructures. This is why they are often embedded in IoT platforms so that you can connect to any device and make virtually any machine or piece of legacy equipment IoT-ready.

Popular IoT Development Platforms: 2021 Edition

The Internet of things or IoT is a real trend that is apparently gaining popularity among other things. We all might have heard about the buzzword ‘IoT’ at some point in our lives either from a friend, a blog post, or people walking by on a sidewalk. IoT is all about 'physical devices connected to the internet,' in other words, ‘Simply, the Internet of Things is made up of devices — from simple sensors to smartphones and wearables — connected together,’ Matthew Evans, the IoT program head at techUK describes IoT in a nutshell.

The Brief History of IoT

The year 1999 is considered huge for IoT. The term ‘Internet of Things' was coined by Kevin Ashton, executive director of the Auto-ID Center. According to British tech pioneer, Kevin Ashton,

5 Tech Trends Driving Growth in Automotive Manufacturing

Introduction

New and emerging technologies are playing a major role in the future of automotive manufacturing. As tech like smart robotics and the Industrial Internet of Things (IIoT) transforms automaking at large, information technology is becoming an increasingly important driver of growth in the industry.

At the same time, shifting consumer preferences and the growing importance of sustainability in the industry are also having a significant impact on manufacturing processes.

How IoT Technology Is Being Used to Fight Against Corona Virus

As we all have heard about the current outbreak of COVID-19 that was first evolved from Wuhan, China, on December 31, 2019. With rapidly spreading diseases like COVID-19 are the epic concerns for medical professionals in all places around the world.

Medical authorities, as well as citizens, are now using IoT technology to inform people to avoid walking outside in the absence of masks and estimate their temperature from a distance with the help of drones. Various technologies have been acquired by China to handle the deadly virus spread across the country. The Wuhan coronavirus outbreak has begun to be a worldwide catastrophe, causing thousands dead, leaving millions at a risk, economies blocked, factories, as well as cities, are under lockdown.
