Description

The HLK-LD2415H is a compact, integrated millimeter-wave radar module that combines a microstrip antenna, radio frequency circuit, and digital signal processor into a single unit. It operates on the 24GHz ISM band (specifically 24.125 GHz) and utilizes Doppler radar principles to detect the speed of moving targets, directly outputting processed digital speed information.

Engineered for high frequency stability and measurement accuracy (±1 km/h), this sensor is built for demanding outdoor environments. Its robust construction and wide operating temperature range ensure reliable performance in traffic management and industrial speed monitoring applications, providing a direct serial data stream for easy integration into control systems.

Key Features

  • Integrated K-band RF chip and microstrip antenna for compact, reliable design.
  • High-precision speed measurement with an accuracy of ±1 km/h across the full 1-240 km/h range.
  • Dual communication interfaces: industrial-standard RS485 for long-distance networks and 3.3V/5V TTL UART for direct MCU connection.
  • Extended detection capability for moving vehicles at distances of 180 meters or greater.
  • Ruggedized for outdoor use with an operating temperature range of -20°C to +85°C.
  • Low-power RF architecture optimized for continuous operation in traffic monitoring systems.

Applications

  • Traffic speed monitoring and display systems for highways and urban roads.
  • Vehicle speed detection for curve warning and intersection safety systems.
  • Industrial site vehicle speed monitoring and access control.
  • Parking lot and toll gate speed management.
  • Integration into smart city and ITS (Intelligent Transportation System) infrastructure.

Frequently Asked Questions

What is the maximum detection distance of the HLK-LD2415H radar sensor?

The HLK-LD2415H is specified for long-range detection of moving vehicles at distances of 180 meters or greater under typical conditions. The actual maximum range can be influenced by environmental factors, target size, and installation alignment.

What interfaces does this radar module provide for data output?

The module provides two serial communication interfaces: an RS485 port for robust, long-distance industrial networking (often using Modbus RTU protocol) and a 3.3V/5V logic-level TTL UART for direct connection to microcontrollers like Arduino, ESP32, or Raspberry Pi. You select one interface based on your system requirements.

What is the operating voltage and how do I power the sensor?

The module is typically powered via a 5V DC supply connected through its communication interface connector. Always refer to the official datasheet for precise pinout and voltage requirements to ensure proper operation and avoid damage to the sensitive RF circuitry.

Can this sensor measure the speed of pedestrians or bicycles?

The HLK-LD2415H is optimized and calibrated for detecting larger moving vehicles (cars, trucks) at long range. Its sensitivity and signal processing are tuned for these targets, so performance for smaller, slower-moving objects like pedestrians or bicycles may be limited and is not its primary design application.
