Product Description

HLK-LD2410C 24GHz Millimeter Wave Radar Module

= Non-Contact Human Presence and Motion Detection Sensor =

The HLKLD2410C is a highsensitivity 24GHz millimeter wave radar module for non-contact heartbeat and motion detection. Using FMCW technology, it reliably identifies both moving and stationary human presence in indoor environments.

Detects Motion and Static Presence - Identifies breathing and subtle movement
Long Detection Range - Up to 6 meters with ±60° coverage angle
Supply voltage is 5V with current consumption ~79mA
Default UART baud rate is 256000 for configuration
IO output level is 3.3V - use level shifting for 5V microcontrollers

== Applications ==

  1. Smart lighting and HVAC control
  2. Security and alarm systems
  3. Occupancy monitoring
  4. Smart home automation
  5. Energy management
Reliable Presence Detection Detects breathing through nonconductive materials
Wide Compatibility - Works with Arduino, ESP32, ESPHome, and Tasmota

√ Plug and play assembly

√ FCC and CE spectrum certified

√ Supports GPIO and serial output

= Connection Guide =

To ESP32/Arduino:

  • VCC: 5V (supply capacity >200mA)
  • GND: Ground
  • TX: Connect to MCU RX (3.3V logic)
  • RX: Connect to MCU TX (3.3V logic)
  • OUT: GPIO output (optional, 3.3V)
Use femaletofemale jumper wires for quick prototyping
Visual configuration tool requires USB-UART adapter
UART is 3.3V level - use level shifting for 5V microcontrollers
Input power supply must provide >200mA for reliable operation

= Configuration Notes =

The module features 8 configurable distance gates at 0.75m intervals:

  • Set detection range by configuring zones 2-8
  • Adjust moving and static sensitivity per zone
  • Configure "no-one" delay time (default 5 seconds)
  • Use LD2410 tool or web-based configuration utility

ESPHome Support - Binary presence sensor with adjustable zones

Tasmota Compatible - Commands for sensitivity and duration settings

√ Visual tuning tool available for Windows

√ Bluetooth version available for mobile configuration

= Troubleshooting =

Module not responding:

  • Verify 5V power supply with >200mA capacity
  • Check TX/RX crossover connection
  • Confirm 3.3V logic compatibility

Short detection range:

  • Adjust sensitivity settings via configuration tool
  • Ensure proper mounting orientation
  • Avoid metal obstructions near sensor
