Traffic Speed Sensor Applications

While the Traffic Speed Sensor has features that are normally seen in law enforcement Traffic Radar, such as speed locking and Doppler audio output, it is the perfect speed sensor for any application requiring monitoring road traffic speed or speed management in a mobile environment.
