Telensa is working with the City of Harrisburg, Pennsylvania, to trial smart city technologies featuring smart sensors for traffic, air quality and waste monitoring. The City deployed a Telensa smart street lighting system in 2016 and saw the potential to use this physical and network infrastructure to roll out additional smart technologies.

Telensa partner sensors, including CA Traffic for traffic analytics, Libelium for air quality and FarSite for waste monitoring, have been installed. The data from these sensors is analysed and combined with existing lighting data and displayed in a smart city dashboard. This provides custom visualisation of multiple sensors, showing correlations across departments and driving insights for smarter, more efficient and joined up services. Harrisburg is also set to test the use of technology for Traffic Adaptive Lighting, whereby groups of streetlights can be dynamically adjusted in the central management system using real-time, raw traffic data received from a radar-based sensor. This adaptive lighting results in energy savings of up to 30 percent.

Harrisburg has previously worked with Telensa to deploy over 4,000 connected streetlights spanning the whole city, leading to utility bill reductions of 60-70 percent. The city realised the additional value of their lighting infrastructure as a platform for smart city sensors.

Telensa PLANet is an intelligent street lighting system, consisting of wireless nodes connecting individual lights, a dedicated network owned by the city and a central management application.
