Overview HLK-LD2415H speed radar is a millimeter wave radar module integrating microstrip antenna, radio frequency circuit and signal processing circuit, which directly outputs the speed information of the target. It can be used for long-distance car speed measurement up to 180 meters or more. It adopts integrated radio frequency chip, has extremely high frequency stability and speed measurement accuracy of 1KM/h. It is widely used in speed reminders on various roads such as highways, urban trunk lines, city and county highways, urban and rural trunk roads, as well as road curve and intersection warnings. 2. Feature description - K-band radio frequency integrated circuit design; - Frequency range: 24.125GHz (customizable frequency) - Modulation method: CW detects moving vehicles, detection distance ≥180 meters - Supports 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 movement direction and the radar beam azimuth is zero degrees) - Voltage: 9~24V, current ≤50m A@12V - Output power (EIRP): 20d Bm; actual power consumption ≤1.2W - Antenna angle: horizontal 40°, pitch 16° (3d B beam width, actual...
