Product introduction

The HLK-LD2415H velocity radar is a millimeter wave radar module that integrates microstrip antennas, RF circuits, and signal processing circuits, directly outputting target velocity information. Can be used for long-distance car speed measurement up to 180 meters or more, using integrated RF chips, with extremely high frequency stability and a speed measurement accuracy of 1KM/h. Widely used for speed warning and warning of road bends and intersections on various types of roads such as highways, urban and rural trunk roads, city and county level highways, and urban and rural trunk roads.


Feature Description

 

◆ K-band RF integrated circuit design;


◆ Frequency range: 24.125GHz (customizable frequency)


◆ Modulation method: CW detects moving vehicles with a detection distance of ≥ 180 meters


◆ Support RS485 interface and TTL serial port (baud rate 9600bps)


  Speed measurement range: 1KM/H~240KM/H


◆ The speed measurement error is less than ± 1KM/H (when the angle between the motion direction and the radar beam azimuth is zero degrees)


  Voltage: 9~24V, current ≤ 50mA@12V


  Output power (EIRP): 20dBm; Actual power consumption ≤ 1.2W


◆ Antenna angle: horizontal 40 °, elevation 16 ° (3dB beam width, actual detection angle greater than 4 lanes) ◆ Sensor size: 69 * 53 * 5mm
