The Smart Cities sensor board from Libelium measures noise pollution, dust quantities, structural health, and garbage levels. The board may be combined in a network with other sensor boards for gas monitoring, radiation detection, and Smart Parking, enabling System integrators to create a comprehensive range of services based on the Smart Cities 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. The platform is based on Libelium’s modular Waspmote wireless sensing technology 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 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.
