Libelium, Zaragoza, Spain, has completed its Smart Cities platform with a sensor board that measures noise pollution, dust quantities, structural health, and garbage levels. The new board can be combined in a network with other Libelium sensor boards. Its noise sensor detects sound pressure; its particulate matter dust sensor measures PM-10 concentrations and can measure dust concentrations down to 0.1 µg/m3; the crack sensor can detect displacement as small as 10 µm as well as oscillations and dilations for measuring cracks in public structures; and the ultrasound sensor can measure garbage levels in bins. The board also includes temperature, light, and humidity sensors. The Smart Cities platform is based on the company's Waspmote wireless sensing technology.
