HLK~LD2410 24G FMCW 24GHz Smart Human Presence Sensing Module Millimeter Wave Motion Switch r Module

HLK-LD2410

1. Product introduction

HLK-LD2410 is a high-sensitivity 24GHz human presence status sensing module developed by Hilink Electronics. Its working prince is to FMCW frequency-modulated continuous wave, to detect human targets in the set space, combined with signal proceing, 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 d in indoor scenes to sense whether there is a moving or micro-moving human body in the area, and output the 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 ibly applied to different smart scenarios and terminal products.

2.2 Benefits

LD2410 human body sensing module adopts 24GHz millimeter wave r technology. Compared with other solutions, it has obvious advantages in human body sensing applications:

1. In addition to g sensitive to moving human bodies, it can also sensitively sense static, micro-moving, sitting and lying human bodies that cannot be identified by ditional solutions;

2. It has good envmental adaptability, and the sensing effect is not affected by the surrounding envment such as temperature, brightne, humidity and light fluctuations;

3. It has good shell penetion and can be in the shell to work without opening holes on the surface of the product, which improves the aesthetics of the product;

4. It can ibly configure the farthest sensing distance and the sensitivity on each distance door to achieve ible and fine personalized configuration.

3. Application scenarios

The LD2410 human body sensing module can detect and identify the human body in motion, fretting, standing, sitting and lying down. It supports multi-level adjustment and can be widely d in various scenarios of AIoT. The common types are as follows

Human body r light control

It senses whether there is someone in the space, and automatically controls lights, such as lighting equment in public ps, various r lights, lights, etc.

Human body induction wake-up of advertising screen and other equment

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 g turned on when there are people around and causing personal injury

Automatic and alarm of dangerous ps to prevent people from entering specific high-risk spaces, such as high-risk ps entered by personnel from coal mine

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

Intelligent

and identification of people intruding, staying, etc. within the specified range

4. Hardware Descrtion

4.1 Features

Module size: 7mmx35mm, 5 pin holes are reserved in the hardware (the factory default does not match the pins)

The pin hole diameter is 0.6mm, and the pin spacing is 1.27mm.

5. Visual Configuration Tool Descrtion

In order to facilitate the r to test and configure the module quickly and efficiently, a PC configuration tool is provided. The r can this tool to connect the serial port of the module, read and configure the s of the module, and receive the results reported by the. module. Data, and real-time visual display, which greatly facilitates .the of rs.

How to the host computer tool:

the USB to serial port tool to connect the module serial port correctly

Select the corresponding serial port number in the host computer tool, set the baud rate to 256000, select the engineering mode, and click to connect the device

Ar the corresponding is succeful, click the start on, the right graphical interface will display the test results and data

Ar connecting, if the start on is not clicked, or click stop ar starting,the mode information can be read or set

Note:The s cannot be read and configured ar clicking start, and configuration can only be performed ar stopping.

The interface and common functions of the host computer tool are as follows:

The ball is the target state output indication: red means that there is a moving target, and purple means that there is a stationary target:,Green means no one.

6. Bluetooth instructions (LD2410B / LD2410C)

6.1 Install (English version)

Currently the Asupports Android and IOS platforms, you can download it from this link:https://www.pgyer.com/Lq8p(Android)

You can also go to major astores to search for "HLKTools" and install it.

6.2 Instructions

Open the app, and the asearches for nearby devices. The broadcast name of the device is "HLK-LD2410B_xxxx" (xxxx is the last four dis of the ae). Ar the module is succefully connected, you can view the information, or debug and save the s.

The distance of the Ashould not exceed the Bluetooth signal range (within 4 meters).

The proce of modifying the s of the Bluetooth Ais the same as that of the PC host computer tool.

6.3 Turn on bluetooth again

The Bluetooth function of LD2410B is enabled by default, and Bluetooth can be turned off or turned on through the serial port protocol (see LD2410B serial port communication protocol.pdf). If the bluetooth has been turned off, or the serial port cannot be d, the bluetooth can be turned on again ar the module is powered off and then powered on for more than 5 times within 2~3s.
