The AirQuality Lab: How To Work With IoT Sensors

IoT Sensor: The AirQuality Lab

 

Want to learn about the Internet of Things and how to work with a sensor? I did too! I’ve been experimenting with the “Internet of Things” (IoT) since 2014 and have learned about the challenges with my sensor project: the AirQuality Lab. In the beginning, I just wanted to create something and work with the components. The scope of my side project was to read values from a sensor, transfer it to a thing-backend and then learning from the data. This post starts with the basic setup of the Thing and the following posts will cover further points.

After finishing a project in late 2014, I played around to learn a bit more about the Internet of Things (IoT) stuff for my next project. So, it was (and is) proposed, that “everything is connected in 2020” and I had to think about a product, product strategy and technical implementation in this area. Our thoughts about a domain model for IoT at this time was, to reduce everything to a source and a drain. Well, as hardware is cheap (but this is not all) I bought a Raspberry PI, a bunch of sensors and a small LCD display. Inspired by the CubeSensors, I wanted to measure air quality with the sensors and work with the derived data. This should help to understand how things process data, how to transfer it, how to analyze and derive information from it. I started the AirQuality Lab.

Retrospective December 2016

Slogan of the month: The intellectual capital of your business has two legs and walks home every day.

What have I done:

  • Had nice workshops at Fraunhofer Institute for Big Data Analytics
  • Successfully finished hard work on a internal data center migration with the Cloud of Things team
  • Planted the seeds for the hosting quality improvements
  • Worked on the performance of my blog. Improved site performance by 40%. PHP upgrade to v7 was the most gain. Performance could be better but for my kind of hosting it’s very good.
  • Designed strategy, corner milestones and goals for 2017
  • Prepared my talk for Bonn Agile Meetup January: IoT und Bastelprojekte (more on this later in this blog)
  • Enjoyed Christmas and New Year’s Eve vacation

IoT hardware is cheap, but other things are difficult

Internet of Things - Raspberry PiIn the early days of the Internet of Things hype, the industry stated that computing power and accessories are cheap and ubiquitous. Read: available and ready to use. The good part of this statement is, that it is true. Partly. RaspberryPi, Arduino, Seed Studio Groove, Adafruit Feather and so on are cheap and versatile computing devices, available on many online retailers. Several toolkits and online resources help the hackers and makers to prototype and develop products. Also many online platforms are ready for the users to connect and manage the things.

Nonetheless is the Internet of Things not as ready as the industry states. You can prototype fast, but if you would like to adapt the Internet of Things for your business. If you compare the Gartner Hype Cycle for Emerging Technologies from 2015 and 2016 you may see, that the Internet of Things was dropped. While not sure if intentionally or not, it can’t be found on the plateau of productivity. I would place it in the trough of disillusion. For example, here are some topics, the industry is struggling with.

Favorite slogan: So we are doomed!

What have I done:

  • Worked hard on launching new Cloud of Things Features: New Cockpit App is out!
  • Wonder how someone can setup a MongoDB Docker Cluster without persistence!?
  • Coded on some Cloud of Things API and Client stuff Had a new record on contributing code to Github: Longest streak 7 days
    January 30 – February 5.
  • Updating servers for glibc vulnerability.
  • Start planning for big CoT team ramp-up. Scale from one to four teams in one month. Big experiment.
  • Had a week of vacation. Practiced not to work. Successful.

Retrospective January 2016

Favorite slogan: You want to get things done, not building an inventory of unfinished work!

What have I done:

  • Kicked of the first quarter 2016 with hard deadlines for Cloud of Things (watch out for CeBIT)
  • Had some weekend & night shifts because of service outages of Cloud of Things. Turned out that a Gelf4J appender for Graylog caused the issues.
  • Started to play with JavaFX and build a Cloud of Things Genius Client for testing purposes on CoT. (Thanks code.makery for this helpful JavaFX tutorial)
  • Did a talk on our Deutsche Telekom M2M Day 2016
  • I have a new record on contributing to Github

PS: A new try to give a regular update on this blog. Last year I tried a weekly recap, didn’t worked out. But I’m pretty sure that this will work ;-) Continue reading Retrospective January 2016

Internet of Things – my thoughts revisted

I had written my first article about my thoughts on the internet of things about three months ago. I gained some more insights and experiences since then, also, for the beginning of 2016 I feel the time has come for an update.

In my last post I wrote about the maturity of IoT solutions. I think the market is still in the same position. There are many innovators, doing their first steps by digitalizing things and connect them with the Internet (by the end of 2016, do we still talk about the Internet of Things? Or just the Internet?). But the main issue is still the variety of technologies, the problems of physical implementations in retrofit, different types of use cases. Okay, I would make an exception for the Smart Home industry. These points are huge barriers for the implementers in terms of time, budget and quality (ROI).But all the machine manufactures, the producers of all the physical things which doesn’t need a power supply? The big tech companies (e.g. Amazon and Microsoft) are developing tools and services for the market, but they don’t address a major problem: the mass-market digitalization and connection of things.

Internet of Things – My thoughts on IoT

This week I read an article on Wired about the data flow in the Internet of Things. It is essentially about how things are connected and where the data flows through, and provides a good description of the basics of Internet of Things. But connecting machines, devices and other things, and transferring data from one site to the other is just the necessary stuff. Don’t get me wrong – it is pretty complex, perhaps even the most complex part of it. The heterogeneous physical interfaces, protocols, connectivity options and use cases result in maximum diversity on this site. However, with a good range of IoT software systems we can solve any problem. By the way, it is wise to choose an independent IoT system regarding devices and technology. This will assure your investment for the future. Sad but true – the amount of work for integration still does not fit all business…

Raspberry Pi GPIO mit XMPP

Seit einiger Zeit liegen in meiner Schublade zwei Raspberry Pi herum. Die Zeit war reif, endlich etwas damit zu machen. Zunächst wollte ich etwas mit den General-Purpose-Input-Output (GPIO) spielen. Danach dachte ich jedoch, dass es doch mehr Spaß machen würde, wenn ich das Ganze mit XMPP verbinden kann. Dies ist dabei heraus gekommen.
