Smart City technology for Darmstadt

Pilot project for intelligent and adaptive lighting

Location: Darmstadt/Germany, Wixhausen district
Products: , PIR sensors for street lighting, wireless modules with AES-128 end-to-end encryption (IPv6)


Smart and adaptive lighting on a road and footpath in the Wixhausen district of Darmstadt provides security and protects the environment. Presence-controlled lighting saves energy and reduces light pollution.

Smart lighting for Darmstadt
Smart City technology from Tridonic in Darmstadt

Wireless modules connect the street lamps with each another and forward the signals. Data security is ensured by encrypted data transfer. Operators can access the system at any time via the Smart City platform and its management portal.

As part of the “Digital City Darmstadt” project, a street in the Wixhausen area of Darmstadt has been equipped with adaptive lighting. The pilot installation consists of 13 energy-saving LED luminaires equipped with integrated PIR sensors from Tridonic. These sensors detect movement and control the brightness of the street lights as required. Tridonic wireless modules interconnect the lights as an IoT solution and connect them to the internet.
 

Smart lighting for safety and environmental protection

As a car, pedestrian, jogger or cyclist approaches, the smart interconnected street lamps provide adequate illumination. The wireless module in the first street lamp forward the signal to the rest of the lamps so that the entire street run is illuminated. This increases visual comfort and the personal sense of security. If there is no one in the vicinity, the wireless modules dim the lamps, thereby reducing light emission. This ensures that animals and plants are not excessively disturbed by the light, and also saves energy.

Smart City technology from Tridonic

The pyroelectric (PIR) sensors developed by Tridonic detect differences in temperature and thermal radiation from road users. If the sensors detect a vehicle or pedestrian they react by increasing the lighting level and then dim the lights back down again. The LED luminaires and sensors are integrated in a secure network. Data security is ensured by encrypted data transfer. Operators can access the system at any time via the Smart City platform and its management portal, for example to change the grouping of the lamps or the illuminance level. The platform also provides a status report for the lamps, indicates their energy consumption, pending maintenance work and possible faults. There are long-term plans to extend smart street lighting to other places in and around Darmstadt.
