You can choose from a variety kinds of kit at this link. , please select the one you real need.
1. Product introduction
Product Description:
HLK-LD2410B/LD2410Cis 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 and accurate human body sensing algorithms, it realizes high-sensitivity human presence status sensing, and can identify human bodies in motion and stationary states. And auxiliary information such as the distance of the target can be calculated.
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. The farthest sensing distance can reach 5 meters, and the distance resolution is 0.75m. Provides a visual configuration tool, which can easily configure the sensing distance range, sensing sensitivity in different intervals 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 Benefits
2.1 Features

3. Application scenarios
The LD2410B 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 AIoT scenarios. The common types are as follows:
l 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.
l 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.
l 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.
l Smart home appliances
When 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 safety.
l Intelligent security
Detection and identification of people intruding, staying, etc. within the specified range.
