Hi-Link 24G Low Power mmWave Radar Human Body Sensing Module HLK-LD2410S
Important Notice: This product ships from China to our Munich warehouse before final dispatch. Estimated processing time: 2 weeks. Thank you for your patience!
The HLK-LD2410S is a cutting-edge, battery-powered, and ultra-low-power millimeter-wave sensor from the Hi-Link LD2410S series, specifically designed for highly accurate human presence detection. This compact module seamlessly integrates a simplified 24 GHz mmWave sensor hardware platform with intelligent low-power sensing firmware.
The LD2410S hardware features an AIoT-enabled mmWave sensor, a high-performance 24 GHz 1T1R antenna, and essential peripheral circuitry.
Powered by the ICL1112 chip, its smart human presence detection algorithm combines distance measurement technology, advanced radar signal processing, and innovative low-power control mechanisms. This powerful combination enables precise detection of both micro-movements and stationary presence with exceptional accuracy.
Optimized for indoor environments, the firmware operates in a low-power mode to reliably sense whether a human is present, detect motion or subtle movements, and provide real-time updates on detection status. This makes it ideal for applications in smart homes, offices, and various energy-efficient automation systems.
The HLK-LD2410S can detect moving human bodies at distances up to 8 meters. It includes adjustable trigger and hold thresholds, supports real-time human presence status updates, and reports target distance at various intervals, including unmanned states.
With support for both GPIO and UART interfaces, the module offers plug-and-play convenience for a wide array of intelligent devices. Its flexible design facilitates easy integration into scenario-driven applications and terminal products across smart homes, offices, and diverse IoT systems.

3. International Warehouse
Our products are stored in both our U.S. 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.
3.1 U.S. Warehouse
3.2 Chinese Warehouse
We will only arrange YunExpressexpress shipping from Shenzhen for orders with products in the Shenzhen warehouse worth more than €50. Orders directly shipped from our Shenzhen warehouse are handled by YunExpress. Given the complexities of international shipping, the estimated delivery time for these packages is around 10 business days, though this may vary slightly due to customs processes or other uncontrollable factors. Otherwise, the products will first be shipped from China to our U.S. warehouse and then shipped to the final destination.
