24GHz Doppler Radar Sensor Traffic CW Speed Measurement
LDTR04plusm is a radar module integrating a microstrip antenna, RF circuit and signal processing circuit, which directly outputs the speed information of the target.
1. Long-Range Vehicle Detection
Detects large vehicles beyond 150m and small vehicles beyond 100m, ideal for highway and roadside speed monitoring applications.
2. High-Precision Speed Measurement
Achieves ±1 km/h accuracy across a wide speed range of 1 to 240 km/h.
3. Fully Configurable Performance
Sensitivity, direction filtering (approaching/receding), speed units, and output rate are all adjustable via serial commands.
4. Flexible Communication Interfaces
Supports both RS485 and UART (3.3V TTL) with simple ASCII output for easy integration into existing systems.
5. Compact and Reliable
Measures only 70 × 89 × 6.7 mm with robust frequency stability, suitable for roadside and outdoor installation.

Application
It can be used for long-distance car speed measurement over 150 meters. It adopts an integrated RF chip, with extremely high frequency stability and a speed measurement accuracy of up to 1KM/h.
It is widely used for vehicle speed monitoring and early-warning systems on highways, urban trunk roads, county roads, rural roads, and in curves and intersections where safety visibility is limited.
