Smart Cities platform from Libelium allows system integrators to monitor noise, pollution, structural health and waste management
New sensor board completes Libelium's Smart Cities solution, enabling installation of services ranging from noise pollution monitoring to smart waste management
Today's city councils face many challenges requiring effective monitoring. Noise pollution is a common environmental problem affecting both the quality of life and health. Atmospheric pollution - whether in the form of gases such as CO2 and NO2 or dust - is a threat to the health of urban dwellers by causing respiratory diseases. With many of the largest structures - including buildings, bridges and roads - located in cities, ensuring that such structures are sound is critical for public safety. Last, but not least, traffic management is a major challenge with the need to minimise emissions and avoid unnecessary journeys. Until now, some of these challenges have been addressed separately with separate vertical solutions; but city councils cannot afford to deploy one sensor network for each type of problem.
"Urban monitoring - whether relating to noise pollution, traffic management or structural health - can be addressed cost-effectively by wireless sensor networks", says Alicia Asín, Libelium's CEO. She explains, "Libelium is now able to provide system integrators with a complete technology for deploying all the services a Smart City needs using the same modular platform".
The new sensor board includes four new sensors:
- A noise sensor detected sound pressure level (dBSPL). This sensor can be used to detect noise from traffic and people. It is suitable for creating a real-time noise map of a city.
- A particulate matter (dust) sensor for measuring PM-10 concentrations. The sensor is capable of measuring concentrations down to 0.1 micrograms per cubic metre.
- A crack sensor for measuring cracks in public structures such as buildings and bridges. It can detect displacements as small as 10 micrometres as well as oscillations and dilations. This sensor is applicable to Structural Health Monitoring.
- An ultrasound sensor capable of measuring garbage levels in bins. This can enable waste management services to empty rubbish only from bins that are sufficiently full thus saving time and fuel.
The board also includes temperature, light and humidity sensors.
The Smart Cities platform enables system integrators to deploy a heterogeneous wireless sensor network with a combination of sensor boards for city councils. The platform is based on Libelium's modular Waspmote wireless sensing technology.
System integrators can exploit Waspmote's modularity and open source software to create custom solutions for a particular city. Motes or nodes in the network communicate with their gateway using ZigBee radio links. The over the air (OTA) programming capability ensures that sensors can be updated without requiring physical access. The platform's outstanding low power performance ensures that Smart City networks have minimal battery requirements or can work from solar power.
Libelium recently won the Best of Sensors Expo award in the category of data acquisition at the 2011 Sensors Expo for their radiation sensor board.

Waspmote is a modular platform for building wireless sensor networks. The platform comprises: the Waspmote board with microcontroller, memory, battery, accelerometer and sockets for add-on modules; open source API and compiler; a range of ZigBee wireless communication modules offering a choice of protocol versions, radio frequency and range (up to 12 km); wireless modules supporting Bluetooth, GPRS, GPS; and a wide variety of sensor boards enabling the measurement of gases, physical events, agricultural & smart metering parameters. It has outstanding power management - an unprecedented 0.7 microamperes is required in hibernate mode. It supports over the air (OTA) programming. Waspmote is CE, FCC and IC certified.
