The company was founded in 2008 in Rome by two engineers specializing in traffic infrastructure. They developed a wireless parking sensor called Sky Light Sensor using ambient light, IR, and magnetic detection technologies. They now produce and sell systems for traffic and parking management using 868MHz and LoRaWAN radio communication. Their Parking Angel system uses Sky Light sensors, a central unit, and smartphone authorization to manage reserved parking spaces and detect unauthorized vehicles.
