Frequently Asked Questions

What is Sentilo?

Sentilo is an open source sensor and actuator platform designed to fit in the Smart City architecture of any city who looks for openness and easy interoperability. Its objective is to exploit the information "generated by the city" and the layer of sensors deployed across the city to collect and broadcast this information. See more here.

Who is Sentilo for?

Sentilo is aimed at municipalities or organizations who need to process lots of information received from the terrain generated by heterogeneous hardware and software devices (sensors, etc.), and who want a centralized and homogeneous way of managing and distributing these data across their information systems.

It is also aimed at anyone from the IT world interested in contributing to the expansion of the "Internet of Things" and smart cities with the goal of improving citizens' quality of life.

Who is not Sentilo for?

Sentilo is not aimed at end users: they are the ultimate beneficiaries of the services provided system, but they not are going to install the product in their workstations!

How and why was Sentilo created?

Sentilo was initially built to be used as the sensor platform for the City of Barcelona, with an aim of openness from its beginning, using only open source components. After its deployment the City Council has released the code under a free and open source software license, licensing all its rights to the Sentilo Community.

The main idea that inspired the design of this is first and foremost the desire to create a cross-platform oriented infrastructure and data management service, escaping from vertical ITC solutions organized in "silos".

These silo solutions make cities too dependent on specific technologies, solutions or providers and create isolated compartments where the applications cannot access data from other applications. As a result, we get duplicity and multiplicity of data and infrastructures and an upward trend in investment and maintenance costs. The silo structure can only be avoided by creating horizontal and global platforms with a broad and multiorganization scope.

Why the name "Sentilo"?

The word 'Sentilo' means "Sensor" in Esperanto. Naming the project from an Esperanto word was chosen to reflect our intention of openness and universality in the use of Sentilo.

How can I get Sentilo?

What license is used for Sentilo?

Sentilo is free and open source software, licensed under a dual licensing regime, under the EUPL 1.1 and/or LGPL3 licenses (or later versions).

Can I build a commercial product on top of Sentilo Platform?

There are no restrictions to commercial use of Sentilo, particularly building a commercial product on top of (or that uses) Sentilo: you may build and install Sentilo and sell services or license software extensions to third parties. You may also install Sentilo and provide your services on a (for payment) SaaS basis. If you distribute any Sentilo software (or any modification to the original software), you need to ensure that the end-user/client gets a copy of the source code of this software - but not of any extensions, plug-ins or applications that use the Sentilo code as a platform.

What are the future plans for Sentilo?

Barcelona City Council is committed to keep on improving and enlarging the functionalities of the sensor platform. For more information, have a look at Sentilo roadmap.

How and where is Sentilo tested?

Barcelona City Council has been using the platform for two years (since beginning 2013) and is committed to improve the system with different features in the next months.
Sentilo has also been tested in several cities worldwide and used in some Catalonian municipalities.

In which platforms has been Sentilo tested ?

The first deployment for the Barcelona City Council has been tested in the following infraestructure:

  • Four virtual machines, two for the front-ends and another two for the back-end
  • All of them use as operating system Ubuntu server LTS 12.04
  • The real time database server(Redis) works with 16 GB of memory and 36 GB of hard disk
  • The other three servers works with 4 GB of memory and 16 GB of hard disk

Another deployment configuration should work properly, always keeping in mind the expected load by the system.
There also a virtual machine ready for use that can be used for testing purposes.
