24GHz Doppler Radar Sensor 1-240km/h Mmwave Radar
LDTR20VDA speed radar is a millimeter-wave radar module integrating a microstrip antenna, a radio frequency circuit and a signal processing circuit, which directly outputs the speed information of the target.
1. Long Detection Range
Detects vehicles beyond 180 meters, ideal for highways and high-speed road monitoring.
2. High-Precision Speed Measurement
Achieves ≤ ±1 km/h accuracy across a wide range of 1 to 240 km/h.
3. Wide Coverage Angle
Horizontal ±20° beam width covers more than 4 lanes, reducing the need for multiple sensors.
4. Ultra-Low Power Consumption
Consumes only ≤50mA at 12V, suitable for solar-powered or remote installations.
5. Flexible Integration
Supports RS485, UART, and direct alarm outputs for easy connection to speed signs, cameras, or controllers.
