Taltech and Thinnect are building world´s largest smart city sensor network in Tallinn

The Institute of Software Science of Taltech University and startup company Thinnect are developing technology that can monitor urban air and measure traffic flows via hundreds of sensors powered by solar panels and connected by mesh network.

Sensor hubs are placed to street lighting posts of Tallinn and are connected to a network. Different combinations of sensors can measure noise, sound radars can analyse traffic conditions and microphone arrays can record anything for further scientific research. For example, a student of taltech collected birdsongs and analysed different bird species heard my microphone arrays over the city.

It is possible to analyse traffic data in real time by city traffic board and measure noise levels according to traffic. For example, it is possible to see if maximum speed limit lowered, how noise and air quality will change.

There are over 900 sensors over the city measuring different measurements and they will be added to city more.

It is one of the biggest IoT networks in city what can be used for different research projects and data collection for Smart City solutions.
