Encryption Libraries for Waspmote Sensor Networks (AES / RSA)

Libelium has released a set of Encryption Libraries for Waspmote and Plug & Sense!™ sensor platforms in order to ensure the authentication, confidentiality (privacy) and integrity of the information gathered by the sensors. To do so different cryptography algorithms including AES 256 and RSA 1024 have been implemented in the libraries and released under an open source license.

Libelium releases Waspmote Plug & Sense!

Libelium lanunches today Waspmote Plug & Sense!™, a new line of Libelium encapsulated wireless sensor devices allowing system integrators to implement scalable, modular wireless sensor networks and reduce installation time from days to hours. Each Waspmote Plug & Sense! node is equipped with six connectors to which sensor probes can be attached directly, allowing services to be scalable and sustainable. The new platform may be solar powered to allow energy harvesting and years of autonomy.

Raspberry Pi to Arduino shields connection bridge

The idea behind the Raspberry Pi to Arduino shields connection bridge is to allow to use any of the shields, boards and modules designed for Arduino in Raspberry Pi. It includes also the possibility of connecting digital and analog sensors, using the same pinout of Arduino but with the power and capabilities of Raspberry.

In order to make complete the compatibility we have created the arduPi library which allows to use Raspberry with the same code used in Arduino. To do so, we have implemented conversion functions so that you can control in the same way as in Arduino all the I/O interfaces: i2C, SPI, UART, analog, digital, in Raspberry Pi.

Let’s summarize what we can do using this shield along with the arduPi library:

  • Connect any Arduino Wireless module in Raspberry. Some examples: XBee 802.15.4/XBee ZigBee, RFID, NFC, Bluetooth, Bluetooth Pro, Wifi, GPRS, 3G
  • Connect any sensor (analog 0-5V, digital) to Raspberry Pi with a precession of 16b using the ADC integrated. Connect also complex sensors through i2C and UART buses
  • Connect any Arduino specific shield such as: Radiation sensor shield, CanBus, Relay shield,…
  • Connect any electronic module or actuator which works over i2C, SPI, UART

Measuring the inertial forces in two of the most savage roller coasters with wireless sensors

Libelium has tested his sensor platform Waspmote in two of the most savage roller coasters of the world in the Port Aventura theme park (Spain). Waspmote integrates a powerful and accurate accelerometer to measure inertial forces up to +-8g on 3 axis (X, Y, Z) with output data rates up to 1kHz. The tests include 8 complete inversions at a max speed of 135km/h. Data is recorded in the internal SD card and sent via Wifi to a SmartPhone using an Adhoc connection. Read more.

Meshlium Xtreme gives 3G connectivity to ZigBee, Wifi and Bluetooth Sensors

Meshlium Xtreme is the new multiprotocol router for wireless sensor networks designed to connect ZigBee, Wifi and Bluetooth sensors to the Internet through 3G connectivity. The new line launched today allows to send the information gathered by hundreds of sensor nodes at the same time, as it counts with an unprecedented “upload to the Cloud” bandwidth of 5.5 Mb/s -more than 10 times faster than compared with traditional GPRS gateways-.

Sensors to Detect iPhone and Android devices

The new sensing technology integrated in Meshlium Xtreme is able to detect any Smartphone (iPhone, Android) in the area by measuring Wifi and Bluetooth activity; allowing to know in real time people and vehicle presence and fluency. Applications of this new technology go from street activity measurement to vehicle traffic management. Read more.

Libelium unveils the top 50 Internet of Things Applications

More than 50 billion devices will be connected to the Internet by 2020, but this new connectivity revolution has already started. Libelium publishes a compilation of 50 cutting edge Internet of Things (IoT) applications. The list is grouped in 12 different vertical markets, showing how the Internet of Things is becoming the next technological revolution. It includes the most trendy scenarios, like Smart Cities where sensors can offer us services like Smart Parking -to find free parking spots in the streets- or managing the intensity of the luminosity in street lights to save energy. Climate change, environmental protection, water quality or CO2 emissions are also addressed by sensor networks and are just some of the examples included in the Smart Water and Smart Environment sections included in the study.
