Light Hacker is an accessory that “hacks” or modifies the behavior of an existing streetlamp. By using a sound sensor and a color filter that responds to ambient noise, Light Hacker changes the color of the emitted light. The device also has a stand-alone internet connection allowing to send real-time sensor readings to an internet server (COSM), providing open data for the development of noise maps and computer software useful for planners, researchers and citizens. It can be reused, transported and installed where required.
