HLK-LD2410
1. Product introduction
HLK-LD2410 is a high-sensitivity 24GHz human presence reputation sensing module progressed by method of Hilink Electronics. Its operating principle is to apply FMCW frequency-modulated continual wave, to come across human targets in the set space, combined with radar sign processing, correct human physique induction algorithm, to achieve immoderate touchy human presence repute sensing, which might identify the human physique in movement and stationary state, and can calculate auxiliary information such as the space to the target.
This product is mainly used in indoor scenes to sense whether or not there's a transferring or micro-moving human physique within the area, and output the detection leads to genuine time. Farthest sensing distance as much as 6 meters, distance resolution 0. Provides a visual configuration tool, which might smoothly configure the sensing distance vary and sensing in numerous durations sensitivity and unmanned delay time, etc., to adapt to various definite application needs.
Support GPIO and UART output, plug and play, and might be flexibly applied to diverse sensible eventualities and terminal products. Product Features and Benefits

2 Benefits
LD2410 human physique sensing module adopts 24GHz millimeter wave radar sensor technology. Compared with various solutions, it has obvious advantages in human physique sensing applications:
1. In addition to being touchy to shifting human bodies, it will additionally sensitively sense static, micro-moving, sitting and lying human bodies that can not be recognized via standard solutions;2. It has good environmental adaptability, and the sensing impact isn't always plagued by the surrounding environment resembling temperature, brightness, humidity and light fluctuations;3. It has pleasant shell penetration and can be hidden within the shell to paintings with out 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 realize flexible and tremendous customized configuration.
3. Application situations
The LD2410 human body sensing module can come upon and title the human physique in motion, fretting, standing, sitting and lying down. It helps multi-level parameter adjustment and might be extensively utilized in various situations of AIoT. The regular types are as followsHuman body sensor light controlIt senses whether or not there may be somebody in the space, and automatically controls lights, corresponding to lighting fixtures kit in public places, various sensor lights, bulb lights, and so forth body induction wake-up of advertising and marketing display and different equipmentAutomatically turn on when humans come, and routinely sleep when nobody involves save power, news shipping is extra accurate and efficientLife security protectionUV lamp work protection, to prevent the UV lamp from being grew to turn into on when there are humans around and causing own injuryAutomatic detection and alarm of risky places to stop humans from coming into definite high-risk spaces, similar to high-risk locations entered via body of employees from coal mine blastingSmart home appliancesWhen there is no one in the room for an extended time, the TV, air conditioner and varied electric home equipment are mechanically grew to become off, saving energy and safetyIntelligent securityDetection and identification of folks intruding, staying, etc. in the specified range4. Hardware Description
4 FeaturesModule size: 7mmx35mm, five pin holes are reserved in the hardware (the manufacturing facility default does not tournament the pins)The pin gap diameter is 0, and the pin spacing is 1.
four Pin definition5. Visual Configuration Tool Description
In order to facilitate the patron to test and configure the module quickly and efficiently, a PC configuration gadget is provided. The user can use this application utility to connect the serial port of the module, learn and configure the parameters of the module, and procure the detection results reported by way of the. module. Data, and real-time visual display, which greatly facilitates use of users.
How to apply the host laptop computer tool:Use the USB to serial port device to attach the module serial port correctlySelect the corresponding serial port number in the host pc tool, set the baud price to 256000, choose the engineering mode, and click to attach the deviceAfter the corresponding is successful, click on the start button, the right graphical interface will reveal the check outcomes and dataAfter connecting, if the beginning button isn't always clicked, or click on give up after starting,the mode parameter news could be read or setNote:The parameters cannot be study and configured after clicking start, and configuration can totally be played after stopping.
The interface and common functions of the host laptop computer machine are as follows:6. Bluetooth instructions (LD2410B / LD2410C)
6 Install application (English version)
Currently the APP helps Android and IOS platforms, you might achieve it from this link: also can visit main app stores to look for "HLKRadarTools" and set up it Instructions
Open the app, and the app searches for nearby radar devices. The broadcast name of the mechanical device is "HLK-LD2410B_xxxx" (xxxx is the ultimate four digits of the mac address). After the module is efficiently connected, you may view the radar information, or debug and save the parameters use distance of the APP should not exceed the Bluetooth signal vary (within four meters) technique of enhancing the radar parameters of the Bluetooth APP is analogous to that of the PC host laptop computer tool.
6 Turn on bluetooth again
The Bluetooth function of LD2410B is enabled through default, and Bluetooth can be grew to become off or grew to develop into on during the serial port protocol (see LD2410B serial port verbal exchange protocol). If the bluetooth has been grew to develop into off, or the serial port can't be used, the bluetooth would be grew to become on back after the module is powered off and then powered on for more than 5 occasions within 2~3s APP supports Android and IOSplatforms can seek for"HLKRadarRTools in primary app。stores and set up it the close by radar kit throughAPP. The broadcast call of the equipment is"HLK-LD2410B-XXXX (XXXX is the final 4 macaddresses). After the relationship is successful,you can view the radar news and setparameters. Search/ Bluetooth. View parameters environment
Note: APP use distance needs to be inside thesignal fluctuate of Bluetooth-compatible (<4m)ec-buying Bluetooth-compatible function is on bydefault, and may be turned off by way of theserial port protocol. If theBfuetooth-compatible is turned off and themserial port can't be used, theBluetooth-compatible would be turned on againafter power off for more than 5 times in 2-3S.
