1. Product introductionHLK-LD2410C is a high-sensitivity 24GHz human presence status sensing module developed by Hilink Electronics. Its working principle is to use FMCW frequency-modulated continuous wave, to detect human targets in the set space, combined with radar signal processing, accurate human body induction algorithm, to achieve high sensitive human presence status sensing, which can identify the human body in motion and stationary state, and can calculate auxiliary information such as the distance to the target.This product is mainly used in indoor scenes to sense whether there is a moving or micro-moving human body in the area, and output the detection results in real time. Farthest sensing distance up to 6 meters, distance resolution 0.75m. Provides a visual configuration tool, which can easily configure the sensing distance range and sensing in different intervals sensitivity and unmanned delay time, etc., to adapt to different specific application needs.Support GPIO and UART output, plug and play, and can be flexibly applied to different smart scenarios and terminal products.2. Product Features and Benefits2.1 FeaturesPlug and play, easy assemblyThe longest sensing distance is up to 5 metersLarge detection angle, coverage up to 60 degreesAccurate identification within the interval, support the division of the sensing range, and shield the interference outside the intervalMulti-level intelligent parameter adjustment to meet the needs of scee changesVisual debugging and configuration toolsSmall and simplified, the minimum size is only 16mmx22mmSupports various installation methods such as ceiling hanging and wall hanging24GHz ISM band, compliant with FCC and CE spectrum regulations512V wide voltage power supplyThe ultimate cost-effective choice2.2 BenefitsLD2410C human body sensing module adopts 24GHz millimeter wave radar sensor technology. Compared with other solutions, it has obvious advantages in human body sensing applications:1. In addition to being sensitive to moving human bodies, it can also sensitively sense static, micro-moving, sitting and lying human bodies that cannot be identified by traditional solutions;2. It has good environmental adaptability, and the sensing effect is not affected by the surrounding environment such as temperature, brightness, humidity and light fluctuations;3. It has 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;4. It can flexibly configure the farthest sensing distance and the sensitivity on each distance door to achieve flexible and fine personalized configuration.3. Application scenariosThe LD2410C human body sensing module can detect and identify the human body in motion, fretting, standing, sitting and lying down. It supports multi-level parameter adjustment and can be widely used in various scenarios of AIoT. The common types are as followsHuman body sensor light controlIt 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 equipmentAutomatically turn on when people come, and automatically sleep when no one comes to save power, information delivery is more accurate and efficientLife safety protectionUV lamp work protection, to prevent the UV lamp from being turned on when there are people around and causing personal injuryAutomatic 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 blastingSmart home appliancesWhen there is no one in the room for a long time, the TV, air conditioner and other electrical appliances are automatically turned off, saving energy and safetyIntelligent securityDetection and identification of people intruding, staying, etc. within the specified range4.
