LD2410B is a highly sensitive 24GHz human presence status sensing module developed by Hi-link. It operates based on the principle of using FMCW (Frequency-Modulated Continuous Wave) to detect human targets within a defined space. Through the combination of radar signal processing and a precise human body sensing algorithm, it achieves high-sensitivity sensing of human presence status, capable of identifying both moving and stationary human bodies. Additionally, it can calculate auxiliary information such as the distance of the target.
Support GPIO and UART output, plug and play, and can be flexibly applied to different smart scenarios and terminal products.
Product parameters
Solution Advantage
LD2410 human body sensing module adopts 24GHz millimeter wave radar sensor technology. Compared with other solutions, it has obvious advantages in human body sensing applications:
-
In addition to being sensitive to the moving human body, it can also sensitively sense the static, fretting, and sitting and lying movements of the human body that cannot be recognized by traditional solutions.；
-
It has good environmental adaptability, and the sensing effect is not affected by the surrounding environment such as temperature, brightness, humidity and light fluctuations；
-
With good shell penetration and can be hidden in the shell to work without opening holes on the surface of the product, which improves the aesthetics of the product；
-
Flexible configuration of the farthest sensing distance and the sensitivity on each distance door for flexible and fine-tuned personalization；
Application
Human body sensor light control
It senses whether there is someone in the space, and automatically controls lights, such as lighting equipment in public places, various sensor lights, bulb lights, etc.
Human body induction wake-up of advertising screen and other equipment
Automatically turn on when people come, and automatically sleep when no one comes to save power, information delivery is more accurate and efficient.
Life safety protection
UV lamp work protection, to prevent the UV lamp from being turned on when there are people around and causing personal injury.
Automatic detection and alarm of dangerous places to prevent people from entering specific high-risk spaces, such as high-risk places entered by personnel from coal mine blasting.

Important Notice:
- Inventory Status: Please check the inventory status on the product page. Our system displays real-time stock for our Munich and Long Beach warehouses. If an item is out of stock in these locations, it will be marked as "Pre-order". You can still place an order for these items.
- Pre-order Fulfillment: For "Pre-order" items, we arrange the most efficient logistics solution to ensure you receive your goods as quickly as possible. Your package may be shipped directly from our Shenzhen warehouse. Alternatively, as part of our standard restocking process, we may transport the goods to our Munich or Long Beach warehouse first (typically taking 5-10 business days) before dispatching them to you.
- Split Shipments: If your order contains both in-stock and Pre-order items, we will prioritize shipping the in-stock items from the local warehouse immediately. The remaining Pre-order items will be sent to you in a separate shipment once they are ready.
3. International Warehouse
Our products are stored in our Munich, Long Beach, and Shenzhen warehouses to provide more flexible logistics solutions tailored to different regions and customer needs. On each product's description page, we indicate the specific warehouse location to help you better plan your purchase and delivery schedule.

Otherwise, products will be restocked to our Munich or US warehouses before final delivery, as detailed in the "Important Notice" above.
