New IoT Sensor Platform for Smart Cities Aims to Improve Accuracy in Sound Level and Air Quality Sensors

Today, at Smart City Expo, Libelium presents the new generation of the IoT Sensor Plaform for Smart Cities with more accurate sound level and air quality sensors. These sensors address current market demands of higher precision and are aimed to complete the professional equipments to increase city capillarity.

Traffic noise and air pollution together represent the most important environmental risk factors in urbanized societies. Increased awareness of the societal burden of these factors is intensifying the efforts for effective legislation. “Up to 3.7 million people die yearly in the world due to exposure to pollution in cities. The UN Climate Change Conference COP22 is agreeing to implement climate finance to reduce gas emissions so developed countries have a commitment to invest $100 billion annualy by 2020 and the smart cities market needs accurate technology to comply with legislation”, reasons Alicia Asín, Libelium CEO.

In this emerging scenario, Libelium has improved its sensors design according to regulations of noise and environmental control. A new set of factory-calibrated gas sensors allows to calculate the AQI (Air Quality Index) following international worldwide directives, measuring CO, NO, NO2, SO2 and dust/particle matter (PM1/PM2.5/PM10). This new generation of gas sensors offers extra accuracy detecting variations as small as 0.1 ppm in many cases.

The new sound level sensor can be placed outdoors as it includes a waterproof microphone. It has been designed following the specifications of the IEC 61672 standard for sonometers with an accuracy of +/-0.5dBA. The value given by the sensor is the Leq (Equivalent Continuous Sound Level), a magnitude used in regulations of noise control at workplaces and outdoors and perfect for the creation of sound level maps.

“The accuracy of these sensors and the fact of being wireless communicated with any Cloud platform in real time make them the perfect complement to extend the capillarity of these services in Smart Cities” concludes David Gascón, Libelium CTO.

Libelium Plug&Sense! Smart Cities is fully certified with CE (Europe), FCC (US), IC (Canada), ANATEL (Brazil), RCM (Australia), PTCRB (US) and AT&T (US).
