Description
LD2410C 24GHz Human Presence Sensor Module
The LD2410C is an advanced presence sensor that detects human movements using 24 GHz FMCW millimeter-wave radar. Unlike traditional PIR sensors, this module operates via microwaves and the Doppler effect, allowing it to perceive movements through almost all materials except metal.
Main Features
- Detection range from 0.75 to 6 meters with a detection angle of ± 60°
- Detects both moving and stationary persons
- Status readable via "OUT" pin, UART interface, or Bluetooth
- Adjustable sensitivity, detection areas, and delay via app or PC
- Operates between -40 °C and +85 °C, insensitive to light, dust, and moisture
- Compact size: 22 x 16 mm and low power consumption of 79 mA at 5 V
- Plug-and-play with 5-pin connector, suitable for Arduino, Raspberry Pi, ESP32
- Compatible with Home Assistant and ESP Home
Applications
- Direct connection to Home Assistant via Bluetooth for smart automation
- Configuration with HLKRadarTool app (Android/iOS) for adjusting delay and detection distance
- Reading with microcontrollers such as ESP32 via available LD2410 library
- Applications in intelligent lighting, HVAC systems, and security
Technical Details
- Power supply: 5 V
- Power consumption: 79 mA
- Dimensions: 22 x 16 mm
- Detection technology: 24 GHz FMCW radar, Doppler effect
- Interfaces: OUT pin, UART, Bluetooth
- Temperature range: -40 °C to +85 °C
The LD2410C offers a reliable and flexible solution for detecting human presence, even in challenging environments. Thanks to easy integration and extensive configuration options, this sensor is suitable for various smart applications without requiring extensive programming knowledge.
