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[citation:1][citation:7].

Detects Motion and Static Presence - Identifies breathing and subtle movement[citation:1]
Long Detection Range - Up to 6 meters with ±60° coverage angle[citation:1][citation:7]
Supply voltage is 5V with current consumption ~79mA[citation:1]
Default UART baud rate is 256000 for configuration[citation:5]
IO output level is 3.3V - use level shifting for 5V microcontrollers[citation:1]

Connection Guide

To ESP32/Arduino:

  • VCC: 5V (supply capacity >200mA)[citation:9]
  • GND: Ground
  • TX: Connect to MCU RX (3.3V logic)[citation:2]
  • RX: Connect to MCU TX (3.3V logic)[citation:2]
  • OUT: GPIO output (optional, 3.3V)[citation:9]
Use femaletofemale jumper wires for quick prototyping[citation:2]
Visual configuration tool requires USB-UART adapter[citation:5]
UART is 3.3V level - use level shifting for 5V microcontrollers[citation:1]
Input power supply must provide >200mA for reliable operation[citation:9]

Configuration Notes

The module features 8 configurable distance gates at 0.75m intervals[citation:5]:

  • 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[citation:5]

ESPHome Support - Binary presence sensor with adjustable zones[citation:2]

Tasmota Compatible - Commands for sensitivity and duration settings[citation:9]

√ Visual tuning tool available for Windows[citation:5]

√ Bluetooth version available for mobile configuration[citation:5][citation:12]

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
