XIITIA 3pcs LD2410S Human Presence Radar Sensor Module HLK-LD2410 LD2410 Millimeter Wave Non-Contact 24GHz ISM Band Serial Port IO Level Output

The HLK-LD2410S is a battery-powered, ultra-low-power human presence millimeter-wave sensor from Hailinks LD2410S series, comprising the streamlined 24GHz millimeter-wave sensor hardware (LD2410S) and low-power human presence detection smart algorithm firmware. ^^ The LD2410S hardware integrates an AloT millimeter-wave sensor, a high-performance 24GHz transmit-receive antenna and peripheral circuitry; the low-power intelligent human presence detection algorithm utilizes millimeter-wave sensor distance measurement technology and the ICL1112 chips advanced proprietary radar signal processing and low-power control technology to achieve precise detection of moving, slightly moving, and stationary humans. ^^ The low-power human presence detection algorithm firmware is primarily designed for indoor applications, detecting whether there are moving or slightly moving humans within the sensing area in low-power mode and refreshing detection results in real time.

^^ The HLK-LD2410S has a farthest detection range of 8 meters for moving humans. It supports configurable trigger and hold thresholds for different ranges, human presence status, reporting frequency for target human distance, as well as reporting intervals when no human is present. ^^ The HLK-LD2410S supports GPIO and UART interfaces, offering plug-and-play functionality and flexible application in various smart scenarios and end-user products.
