LD2410B FMCW 24G

LD2410B FMCW Sensor, Smart human presence sensor, bluetooth

The HLK-LD2410B is a 24 GHz millimeter-wave radar sensor module specifically engineered for the detection of human presence and motion. It utilizes Frequency Modulated Continuous Wave (FMCW) radar technology, which allows for precise identification of both stationary and moving human bodies. Notably, this module is capable of detecting micro-movements, such as a person sitting or lying down, a functionality that traditional sensors, including infrared and ultrasonic devices, typically lack.

This sensor is designed for use in indoor environments and is capable of detecting human presence within a range of up to 5 meters. With compact dimensions of 7mm x 35mm, it is suitable for integration into various devices and applications. The module supports both Bluetooth and UART communication protocols, enabling users to configure and adjust the sensor through mobile applications or personal computers.

etection Range: The module can detect human presence at distances up to 5 meters, with a resolution of 0.75 meters, ensuring high precision.

Wide Detection Angle: The sensor covers a ±60° detection angle, allowing it to monitor a broad area.

Micro-Motion Detection: In addition to detecting moving human bodies, the module can detect static and micro-movements, such as sitting or lying down.

Adjustable Sensitivity: Users can adjust the sensitivity to fine-tune detection parameters based on specific needs.

Bluetooth & UART Communication: The sensor supports Bluetooth and UART interfaces, enabling flexible configuration via mobile apps or direct device integration.

Strong Environmental Adaptability: The sensor operates effectively under various environmental conditions, unaffected by factors like temperature, humidity, and light.

Compact Design: The module is very small (7mm x 35mm), making it easy to integrate into various devices such as smart home systems or security devices.

The LD2410B human presence sensing module uses 24GHz millimeter-wave radar technology, offering significant advantages in human detection applications compared to other solutions:

Enhanced Sensitivity: In addition to its capacity to detect moving human bodies, the system is also capable of identifying static subjects, micro-movements, and individuals who are sitting or lying down—qualities that traditional solutions typically fail to recognize.

Excellent Environmental Adaptability: In contrast to infrared or ultrasonic sensors, the LD2410B remains unaffected by environmental variables such as temperature, brightness, humidity, and light fluctuations. This characteristic guarantees stable performance across diverse conditions.

Good Shell Penetration: The sensor can be concealed within a protective casing without compromising its functionality. This design approach eliminates the necessity for surface perforations on the product, thereby enhancing its aesthetic appeal and mitigating the risk of electromagnetic interference or structural complications.

Flexible Configuration of Detection Range and Sensitivity: Users have the capability to configure the maximum detection range and sensitivity for each distance gate with a high degree of flexibility, facilitating a tailored and personalized experience.

Bluetooth Functionality: The module is equipped with Bluetooth functionality, enabling users to configure radar parameters directly through an application, thereby eliminating the need for a serial port connection. This advancement significantly streamlines the setup process.
