Doppler Radar Sensor

May 22, 2019
OmniPreSense's doppler sensor offers detection distances up to 100 m.

The OPS243 is a radar sensor for traffic monitoring that offers detection distances up to 100 m (328 ft), provides 4 times the detection range of its predecessor, the OPS242, and includes a unique object counting algorithm. This makes the OPS243 an ideal solution for vehicle and people traffic monitoring in Smart City applications. In addition, the OPS243 will carry full FCC/IC modular certification, lowering system costs and time to market.


The OPS243 can see cars and trucks up to 100 m away and has a tight 20-deg. beam width, allowing it to look farther down two-lane roads, and providing more data points for analysis. OmniPreSense makes use of additional data, incorporating a simple counting algorithm. Customers can easily implement a traffic monitoring solution to better understand traffic flows in front of the sensor. Armed with this data they can better optimize operations for improved traffic flow, safety, and energy efficiency.


Future versions of the OPS243 will provide wireless communication options, simplifying the passing of traffic data to the cloud for further analysis. Power consumption is reduced to as low as 0.1W, enabling battery operation in remote locations.
