There is a sensor radar module for intelligent home application scene perception scheme. There are many kinds of non-contact sensing technologies, including infrared ray, ultrasonic wave and millimeter wave. As a sensor and detection technology with higher precision, millimeter wave can detect objects and provide information about distance, speed and Angle of objects. Its operating spectrum range is 30GHz to 300GHz wavelength small, can provide sub-millimeter ranging accuracy. In addition, the millimeter wave body sensor radar module can penetrate certain materials such as plastic, wall panel and clothing, and is not affected by environmental conditions such as rain, fog, dust and snow.
Millimeter wave human presence sensor Radar modules send signals with millimeter wave radar (mm) in the wavelength range of the short wavelength of the electromagnetic spectrum, so the size of the system components required to process millimeter wave signals is very small, which is one of the main advantages of this technology. Another advantage of short wavelength is high resolution, with millimeter-wave systems that analyze distance as wavelength achieving millimeter-level accuracy.
Available millimeter bands include 24GHz, 60GHz, 77GHz and 120GHz, with 24GHz being the most widely used. The 77GHz band is already widely used in automotive ADAS and autonomous driving, but is severely limited in non-automotive applications. 60GHz has become the choice of human-computer interaction for factory automation, building automation, urban traffic management, smart home, Internet of Things applications and other emerging needs.
Recently, I interviewed two people from the millimeter-wave radar sensing technology project and had an in-depth exchange on the millimeter-wave human presence sensor radar module and related module solutions and application scenarios. Now in the form of questions and answers summarized below, to show readers the millimeter wave radar sensing technology in the field of intelligent building and smart home applications of high-precision solutions.
Radar induction technology has been widely used in automotive electronics/industry. Development trend and prospect of millimeter wave body presence sensor radar module sensing technology in Internet of Things/smart city/smart home and other applications. Today, sensors play an important role in how people interact with their devices. This interaction often depends on the interpretation and integration of information from different sources. Machines cannot understand our thoughts or grasp enough of the information needed to properly assess a given situation. So we have to tell devices clearly what we want them to do. This method is inconvenient and a waste of time.
Inspired by the human ability to sense touch, the millimeter-wave body presence sensor radar module intuitive sensing solution aims to simplify the interaction between humans and devices as much as possible. Based on the holistic idea, we combine different sensors with advanced software that mimics human perception to more fully explore the world around us. By combining multiple smart sensors into one coherent intelligent system, our intuitive sensing solution can simplify complex technical processes and make interaction between people and devices very easy. These smart devices intuitively sense the world around them to determine what they should and need to do.
Radar can give objects eyes. Millimeter wave human presence sensor radar module radar can make objects have situational awareness, completely change the man-machine interface, and help realize our intuitive perception concept: make objects (devices) have human senses. Thanks to industry-leading technology, sensors are partners in a variety of application scenarios such as automotive, industrial and consumer products.
Millimeter wave body Presence Sensor Radar module Integrated radar sensor solutions with their compact appearance and extremely low power consumption bring innovative intuitive sensing capabilities to many applications. Radar has proven to be an effective sensor technology in consumer electronics, surveillance, driver assistance and industrial applications for short-range positioning and vital signs tracking.
The radar not only supports existing applications, but also has the capability to implement new applications. The millimeter-wave body presence sensor radar module measures speed, distance and Angle, including horizontal and vertical viewing angles, for accurate 3D mapping and position tracking.
