Product Description
24G Human Presence Radar Sensor Motion Module Product Introduction LD2410 is a high-sensitivity 24GHz human presence status sensing module developed by Hi-Link Electronics. Its working principle is to use FMCW frequency-modulated continuous waves to detect human targets in the set space. Combined with radar signal processing and accurate human body sensing algorithms, it realizes high-sensitivity sensing of human presence status, 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. Supports GPIO and UART output, plug and play, and can be flexibly applied to different smart scenarios and terminal products.Features- Plug and play, easy assembly

Application ScenariosThe LD2410 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 follows.* Human-sensitive lighting controlSensing the human presence in the space,and automatically controls lights, such as lighting equipment in public places, various sensor lights, bulb lights, etc.* Human-sensitive wake-up of advertising screen and other equipmentAutomatically turn on when people come, and automatically hibernate when no one comes to save power, information delivery is more accurate and efficient.* Life safety protectionUV 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.* Smart home appliancesWhen there is no one in the room for a long time, the TV, air conditioner and other electrical appliances will be automatically turned off, energy conservation and safety.
* Smart Security
Detection and identification of people's intrusion, stay and other actions within the specified range
Dimension
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.Installation Conditions* Confirm the minimum installation clearanceIf the radar needs to be installed with a casing, the casing must have good wave-transmitting properties at 24GHz, and cannot contain metal materials or materials that have a shielding effect on electromagnetic waves.* Installation environment requirementsThis product needs to be installed in a suitable environment. If it is used in the following environments, the detection effect will be affected:• There are non-human objects that are continuously moving in the sensing area, such as animals, continuously swinging curtains, large green plants facing the air outlet, etc.• There is a large area of strong reflectors in the sensing area, and the strong reflectors will cause interference to the radar antenna.• When installing on the wall, external interference factors such as air conditioners and electric fans on the top of the room need to be considered.* Precautions during installation• Try to ensure that the radar antenna is facing the area to be detected, and the surrounding area of the antenna is open and unobstructed• To ensure that the installation position of the sensor is firm and stable, the shaking of the radar itself will affect the detection effect.• To ensure there is no movement or vibration on the back of the radar. Due to the penetrating nature of radar waves, the back lobe of the antenna signal may detect moving objects behind the radar. A metal shield or metal backplane can be used to shield the radar back lobe and reduce the impact of objects on the back of the radar•The theoretical distance accuracy of radar is the result obtained through special algorithm processing on the basis of the physical resolution of 0.75 meters. Due to the difference in the size, state, and RCS of the target, the target distance accuracy will fluctuate; at the same time, the longest distance will also fluctuate slightly.Performance and Electrical Parameters| Operating frequency | 24GHz~ 24.25GHz
