Plug & Sense – Smart City Pro


The main applications for the Waspmote Plug & Sense – Smart City PRO  model are noise maps (monitor in real time the acoustic levels in the streets of a city), air quality, waste management, smart lighting, etc. Smart Cities PRO board is to extend the monitoring functionalities from indoor environments to outdoor locations, in order to perform IoT projects in Smart Cities and urban environments.


Some of the Smart Cities sensor applications are :

Smart Parking
Monitoring of parking spaces availability in the city.

Structural health

Monitoring of vibrations and material conditions in buildings, bridges and historical monuments.

Noise Urban Maps

Sound monitoring in bar areas and centric zones in real time.

Smartphone Detection

Detect iPhone and Android devices and in general any device which works with WiFi or Bluetooth interfaces.

Eletromagnetic Field Levels

Measurement of the energy radiated by cell stations and and WiFi routers.

Traffic Congestion

Monitoring of vehicles and pedestrian levels to optimize driving and walking routes.

Smart Lighting

Intelligent and weather adaptive lighting in street lights.

Waste Management

Detection of rubbish levels in containers to optimize the trash collection routes.

Smart Roads

Intelligent Highways with warning messages and diversions according to climate conditions and unexpected events like accidents or traffic jams.


The Smart Cities PRO board adds support for the Noise Level Sensor too…!!
