Sensorlab / Hardware



VESNA is a modular and fully flexible platform for the development of wireless sensor networks developed at the SensorLab @ Jozef Stefan Institute. Based on the high-performance microcontroller with ARM Cortex-M3 core and radio interface spanning over multiple ISM frequency bands it is designed to meet the requirements of diverse applications.

In terms of modularity the platform consists of the VESNA core module and a set of special feature modules (sensor node radio – SNR, sensor node expansion – SNE, sensor node power – SNP) that are used as/if needed. Various peripherals including UART, I2C, SPI, USB, ADC and DAC allow hosting of different sets of sensors and/or actuators including sensors for temperature, humidity, luminance, color, reflectance, pressure, presence, location, sound, acceleration, gasses, motion, range, and actuators such as motor, relay, servo, alarm, … The platform readily supports:

  • communication standards IEEE 802.15.4, IEEE 802.15.1 and IEEE 802.11; 
  • ZigBee, 6LoWPAN, Bluetooth and Wireless M-Bus protocol stacks and technologies; 
  • operating system Contiki; 
  • connection to the Internet via Wi-Fi, Ethernet or GSM/GPRS; 
  • Arduino integrated development environment
  • a variety of energy supply options including battery, solar panel and external power supply. 


Depending on the needs of application it can either come in bare metal variant or running a Contiki. Soon it will become Arduino compatible. It can as well be used to implement fixed or mobile gateway solutions based on Ethernet, GSM/GPRS, Wi-Fi, Bluetooth and HSPA communication networks.

Tomaz's blog entries related to cognitive radio, VESNA and other stuff:


Our paper "Trends in the devlopment of communication networks: Cognitive networks" is the 10th among the 25th most cited articles published since 2009, extracted from Scopus, see all on the Elsevier web site.

Check the "Cognitive radio experimentation with VESNA platform" presentation by Miha Smolnikar at the School on Applications of Open Spectrum and White Spaces Technologies.

We are looking for a C programmers that would join the team developing the VESNA platform. Candidates that have previous experience with electronic circuit design, operating systems or open source projects will have priority.

Together with industrial partners we are working on advanced control of ventilation system with heat recuperation. Read more in Slovenian.

The CFP for the Web of Things workshop is out. Consider submitting a paper.

Carolina Fortuna successfully defended her PhD thesis entitled Dynamic Composition of Communication Services.

The CREW OC2 project CREW-TV (Feb. 1 2013 - March 31 2014) focuses on the experimental coexistence in TV bands and will involve the LOG-a-TEC testbed where also the final demonstration will be given. 

Tomaz talks about the CREW training days on his blog.

The CREW OC2 project CREW-TV will involve the LOG-a-TEC testbed. 

Zoltan Padrah successfully defended his MSc thesis entitled Distributed Spectrum Sensing in Unlicensed Bands Using the VESNA Platform

The Absolute project has had the kick-off meeting in October 2012.

The CITI-SENSE project has had the kick-off meeting in October 2012.

Tomaž talked about VESNA and Cognitive radio in Kibepipa (talk in Slovenian).

Join us at the CREW training days! Program available here.

Check our github to see what we've opened up!

One of the many aplications we use VESNA for is spectrum sensing. Read more about it!


We are constantly open for talented, open minded and hard working undergraduate students, interns and MSc/PhD candidates. Read more.
