With its compact size, wide detection range, and ability to detect micro-movements such as breathing and subtle body shifts, the HLK-LD2410 provides superior sensitivity and stability across various environments.

Key Features of 24GHZ Radar Human Body Motion Detection Sensor Module HLK-LD2410

• 24GHz Radar Technology: Uses millimeter-wave radar for more accurate and stable motion detection compared to traditional PIR sensors. Works effectively in complete darkness or through non-metallic materials like plastic or glass.

• Human Presence Detection: Can detect not only motion but also the presence of a stationary human by sensing micro-movements like breathing or slight posture changes.

• Wide Detection Range: The HLK-LD2410 offers a detection range of up to 6 meters for motion and around 5 meters for presence detection, with a wide 120-degree field of view.

• High Sensitivity: Detects small movements and subtle presence changes, making it ideal for environments that require high precision, such as smart lighting or security alerts.

• Non-Invasive and Privacy-Safe: Unlike camera-based systems, radar technology respects privacy by sensing motion and presence without visual surveillance.

• Low Power Consumption: Optimized for energy efficiency, making it perfect for battery-powered smart devices or IoT systems.

• Compact Design: Small form factor makes it easy to integrate into various electronic enclosures or consumer devices.

• Multiple Output Modes: Offers UART communication and GPIO output, enabling seamless integration with microcontrollers like ESP32, Arduino, and Raspberry Pi.

• Environment Adaptive: Performs reliably in a wide range of lighting conditions and temperatures, from -30°C to 85°C, without false alarms from heat sources or light fluctuations.

Applications of 24GHZ Radar Human Body Motion Detection Sensor Module HLK-LD2410

The HLK-LD2410 24GHz Radar Sensor Module is highly versatile and widely applicable across a range of modern smart and automation systems:

1. Smart Lighting Control

Automatically turns lights on or off based on human presence, significantly improving energy efficiency in residential, commercial, or industrial spaces. Unlike PIR sensors, it can detect still occupants, ensuring lights remain on when needed.

2. Smart Home Automation

Integrates with smart home hubs and systems for intelligent presence-based automation. For instance, it can trigger HVAC systems, alarms, or smart appliances when it detects a person entering or leaving a room.

3. Security and Surveillance

Enhances security systems by detecting motion in real time—even through obstacles such as curtains or thin walls—reducing false alarms and increasing system reliability.

4. Elderly Care and Health Monitoring

In medical and elder care environments, the sensor can be used to monitor the presence and movements of patients without invading privacy, supporting fall detection and health monitoring systems.

5. Energy Management

Helps in reducing energy costs by ensuring devices and systems operate only when human presence is detected, especially in offices, classrooms, and public buildings.

6. Commercial Buildings and Workspaces

Ideal for modern offices and commercial buildings where smart presence detection can help manage lighting, air conditioning, and security efficiently.

Why Choose the HLK-LD2410 Radar Sensor?

1. Superior Accuracy Compared to PIR

Unlike PIR sensors, which rely on detecting infrared radiation and often miss slow or stationary movement, the HLK-LD2410 detects even the slightest human motion using radar technology. This ensures that presence is never overlooked.

2. All-Weather, All-Light Performance

The radar operates independently of light conditions, making it functional in both total darkness and bright sunlight—something many traditional sensors cannot achieve.

3. Privacy-Friendly Design

No image or audio recording involved—radar technology means no personal data is captured, offering a more secure and ethical alternative to camera-based systems.

4. Customizable and Developer-Friendly

With UART interface and easy-to-integrate firmware, developers and engineers can customize the sensor’s behavior to fit their specific project needs. Perfect for OEMs and DIY enthusiasts.

5. Energy Saving Capabilities

By accurately determining room occupancy, the HLK-LD2410 helps reduce unnecessary energy consumption by controlling lights, air conditioning, and other appliances only when needed.

6. Long-Term Durability

Built for industrial-level reliability, the sensor operates flawlessly in extreme environmental conditions and has a long service life with minimal maintenance.
