Short MIIMETIQ definition

Reading time: 2 – 3 minutes

M2MCF and MIIMETIQ

Last months in M2M Cloud Factory we have been working on MIIMETIQ. Last weeks I’ve been thinking about how to define MIIMETIQ shortly and this is my definition, please tell if you can understand something. Of course, you have to know we’re focused in Internet of Things and M2M market.

  • MIIMETIQ is an IoT/M2M framework, so this is the first step to setup to develop your vertical solution.
  • Framework: With a well defined architecture a framework is a set of functions ready to create any application. Everything else is open and adaptable.
  • MIIMETIQ architecture is service oriented and it uses AMQP as a message broker to connect the services.
  • MIIMETIQ has several modules, we define a module as a set of services. Basicly MIIMETIQ have 5 modules:
    • Identity Manager: manage users, groups, roles and all kind of entities the project needs and its security.
    • Assets Manager: a data model manager, the integrator creates the business logics and data models here.
    • Distribution System: this is a set of agnostitc connectivity layers to different types of devices.
    • A E N M: several time series and other signals flow through the AMQP, this data are events and using rules those events could be converted in alarms and some alarms have to be notified to proper services, systems or people.
    • Control Panel UI: this is an administration dashboard, in form of a UI to setup and monitor the most common uses of MIIMETIQ.
  • Using those modules usually the integrators create their own user interface to satisfy customer requiremests. In M2MCF we create those UI using ADUX (Advanced Development User Experience).
  • After configuring MIIMETIQ the integrator has 2 customized APIs to connect their code with MIIMETIQ. One of them is an API REST and another one is AMQP.
  • Finally everything inside MIIMETIQ could be customized, because the flexibility is very important when you have an horizontal solution.

Conferència al Tecnocampus: Internet of Things (IoT) low cost

Reading time: 1 – 2 minutes

Després d’arribar corrent de Cardiff on era aquest dilluns el dimarts vaig arribar a temps per fer la presentació “Internet of Things low cost” als companys del Tecnocampus de Mataró; per cert, unes intal·lacions brutals res a veure amb la EUPMT on vaig estudiar jo fa una colla d’anys. Jo encara diria més, molt millor que no pas la gran Universitat de Cardiff on vaig ser el dilluns.

Pel que fa a la xerrada agraïr a tothom que hi va assistir, a continuació adjunto les transparències pels que vareu ser-hi i pels que no.

Properament pujaré el video, o la part, del video que es va poder gravar. El problema és que són diversos gigues i he de deixar l’ordinador renderitzant cosa que encara no he pogut fer.

El video no conté tota la presentació però té una part important del contingut, així que desitjo que ús sigui útil:

Per cert, una gran part de la presentació esta reciclada de la conferència: Conferència: La revolució dels mini-PC: Raspberry PI, Arduino i més

Firmware of my home heaters (Panstamp = Arduino + TI C1101)

This entry is part 3 of 4 in the series heater

Reading time: < 1 minute Clicking the next link you can get my github repository with the firmware of my home heaters. The code is very simple but useful as we tested last winter at home.

I know all the public documentation is not enough to duplicate my heating project. I’m so sorry but I have a lot of pending home projects to do because I have a lot of under construction things. If you need some help to understand what I have or how to do something feel free to ask.

Conferència: La revolució dels mini-PC: Raspberry PI, Arduino i més

Reading time: 1 – 2 minutes

Ahir al vespre vaig fer una conferència a la FIB (Facultat d’Informàtica de Barcelona) dins de la UPC (Universitat Politècnica de Catalunya). En aquesta xerra vaig estar explicant què és i en que es diferència Arduino i Raspberry PI. A més de presentar tot un conjunt de solucions alternatives i experiències en el tema.

En aquest enllaç podeu trobar les transparències de:  La revolució dels mini-PC: Raspberry PI, Arduino i més. i el video el teniu disponible al servidor de la FIB.

Ara també teniu disponible el video a youtube:

i podeu veure les transparències des d’aquest mateix post:

Espero els vostres feedbacks als comentaris, desitjo que ús sigui útil.

Home heating using Panstamp (Arduino + TI C1101) and SSR

This entry is part 2 of 4 in the series heater

Reading time: 3 – 5 minutes

Last weekend I worked on setting up home heaters using Panstamp. Panstamp is an Arduino board with Texas Instruments radio. Next winter we’re going to control our home heater using connected internet devices like the laptop, tablet o mobile phones. In this post I only want to share some pictures about the process to install the electronics inside the heaters changing the old electronic boards with new custom ones.

The parts:

  • AC/DC transformer, outputs 5V. It’s really cheap, in this case free because I have more than 20 of them from old projects.

  • A small custom PCB designed and made by Daniel Berenguer, the owner of Panstamp. Thanks again Daniel. I bought the PCBs and parts for around 10€ each one.

  • TMP36 temperature sensor. It costs about 1,5€ each one.

  • Solid state relay (SSR) bought in Alied Express web site for less than 5€.

The process:

I used a lot of tools, because DIY aren’t my strong hability.

Next weeks, I’ll come back with this subject to talk about the software part.
