The Wavetronix SmartSensor Matrix™  is a stop bar presence detector designed for use at signalized intersections. The SmartSensor Matrix detects vehicle demand through the use of a 24.125 GHz (K band) operating radio frequency. Using what is classified as frequency modulated continuous wave (FMCW) radar, SmartSensor Matrix detects and reports vehicle presence in as many as 10 lanes simultaneously.

SmartSensor Matrix is a first-of-its-kind radar stop bar detector with Radar Vision™. It delivers the reliability of radar and the simplicity of non-intrusive detection for stop bar presence detection. In many situations, the sensor is installed on the roadside in order to prevent the need for lane closures and traffic control. Once the unit is installed, the configuration process is quick and easy.  After installation, the sensor will require little or no on-site maintenance and can be remotely configured.
