24GHz Automotive Radar Sensor Traffic Speed Sensor
LDTR04PLUSB is a radar module that integrates a microstrip antenna, RF circuit and signal processing circuit, directly outputting 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.
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 Integration
Supports both RS485 and UART interfaces with simple ASCII output for easy connection to existing systems.
5. Rugged & Reliable
IP67-rated waterproof housing and robust Infineon chipset ensure stable operation in outdoor environments.

application
It can be used for long-distance vehicle speed measurement over 100 meters. It adopts an integrated radio frequency 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.
