Today, with the rapid development of technology, various advanced sensor technologies are emerging continuously, bringing great convenience to our lives and production. Among them, the 24G micro-motion sensing radar module plays an important role in many fields due to its unique advantages.
The 24G radar module, such as the hlk-2420 model, adopts a one-transmit and one-receive antenna design, which can achieve precise sensing of human micro-motion and movement. Its working principle is based on microwave technology. By transmitting and receiving microwaves with a frequency of around 24.125GHz, it can sense information such as the presence of objects, movement speed, stationary distance, and the angle at which the objects are located. This radar module uses planar microstrip antenna technology and has significant characteristics such as small size, high integration degree, and sensitive sensing.
Taking the hlk-2420 as an example, its volume is only 20mm×20mm. Such a small size contains powerful functions. In terms of the sensing distance, its close-range sensing can reach 0.2m, and there is no detection blind area. The maximum sensing distance for a moving human body can reach 8m. It has a large detection angle, and the coverage range reaches ±60°. This module also supports the ranging function. Although it is not for precise measurement, it can provide reference data for relevant applications. In terms of power supply, it only requires a 3.3v power supply, supports a wide voltage range of 3.0v - 3.6v, with an average operating current of 50ma, and has low energy consumption, making it suitable for long-term stable operation.
In the field of smart home, the 24G micro-motion sensing radar module shows its great capabilities. It can sense human micro-motion and distance and report the detection results to the main control module, thus realizing the intelligent control of home appliances. In smart switches and smart sockets, when a person approaches, the module senses the human body signal, and the smart switch can automatically turn on the lights, and the smart socket can automatically supply power to the device. When the person leaves, it can automatically turn off, achieving the purpose of energy saving. In smart toilets, such as the scenario where the rd-03e radar module is applied, when a person enters the sensing range, the radar senses the person, the night light turns on, the seat ring is heated, and the toilet lid is opened. When a person waves within the toilet range, the inner ring of the toilet is automatically opened. When the person leaves the sensing range, the toilet turns off the heating, closes the lid, turns off the night light, and activates the flushing and sterilization functions, bringing a convenient and hygienic experience to users.
The field of smart business also cannot do without the 24G radar module. In the commercial lighting scenario, the module can recognize whether a human body is approaching or moving away within the set distance range and light up or turn off the screen in a timely manner. When a customer approaches the product display area, the lighting device automatically turns on to highlight the products. After the customer leaves, the lights automatically turn off, which not only saves energy but also creates a comfortable shopping environment. In some electronic billboards or smart display devices, the screen brightness can also be dynamically adjusted according to the distance between the human body and the screen, further saving power consumption.
Smart lighting is also an important application field of the 24G micro-motion sensing radar module. In public place lighting devices, such as induction lights and bulb lights, the module can identify and sense human bodies and detect positions. In some corridors or stairwells, when someone passes by, the induction light automatically turns on and turns off with a delay after the person leaves. In some large parking lots, by sensing vehicles and pedestrians through the radar module, the on-off of the lighting devices can be reasonably controlled, improving the intelligence level of the lighting system and reducing energy waste.
In addition to the above fields, the 24G radar module also has a wide range of applications in smart security, motion speed measurement, industrial applications, etc. In smart security devices such as induction access control systems, building intercoms, and electronic cat eyes, it can accurately identify the entry and exit of personnel and ensure the safety of the place. In motion speed measurement, products such as running speedometers and golf speedometers can be developed to accurately measure the movement speed of people or objects. In industrial application scenarios such as liquid level measurement, flow rate measurement, and conveyor belt monitoring, it plays a stable and reliable monitoring role.
With its excellent performance and wide applicability, the 24G micro-motion sensing radar module is gradually becoming an indispensable part of smart life and production. With the continuous progress and innovation of technology, it is believed that it will show greater value in more fields and create a more convenient, efficient, and intelligent living environment for us.
