VESNA

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.
