Support

Millimeter-wave detection is a radar technology that can detect objects and provide information on their distance, speed, and angle. This contactless sensing technology operates in the frequency range of 24GHz to 300GHz. Due to its short wavelength, it offers millimeter-level ranging accuracy and can penetrate non-metallic materials like plastic, drywall, and clothing. It is also unaffected by environmental conditions such as rain, fog, dust, and snow.

Measurement Range and Accuracy of Millimeter-Wave?

Creatrol's millimeter-wave sensors can detect human movement within the required range in real-time, accurately identifying motion to control the activation and deactivation of smart devices. The sensing range of millimeter-wave radar depends on the "target object," "detection environment," hardware configuration, and antenna design, requiring specific application testing and evaluation.

How Does Millimeter-Wave Differ from Common Sensors?

Millimeter-wave sensors are theoretically suitable for various radar applications. Compared to radar using 5.8G/2.4G/sub-1G/sub-10G electromagnetic waves, millimeter-wave sensors have lower transmission power and better sensing performance. Unlike infrared, ultrasonic, laser, and camera sensors, millimeter-wave sensors have different detection environment requirements and can complement these common sensing technologies to maximize sensing needs.

Is Millimeter-Wave Sensor Sensitivity Affected by Weather?

Millimeter-wave sensors emit electromagnetic waves and do not rely on medium propagation. With their inherent wavelength characteristics, they possess high energy penetration and diffraction capabilities. They are insensitive to non-metallic material obstructions and have been experimentally verified to effectively penetrate materials like drywall, glass, plastic, and dry surfaces, unaffected by rain, fog, or dust.

Frequently Asked Questions

Detection Principle of Your Sensor

Our radar operates using the FMCW method, whereas infrared sensors utilize the pyroelectric method.

What Distinguishes Your Radar Technology?

Our radar technology employs 24G FMCW (Frequency-Modulated Continuous-Wave) radar, which operates at a higher frequency compared to the 5.8G Doppler radar used by some sensors. This higher frequency enables millimeter-level detection with significantly greater precision. When combined with our proprietary algorithms, it ensures highly accurate detection results. Additionally, our sensor features an integrated light meter function. The light-sensing chip measures real-time illuminance, providing more accurate readings of indoor light levels than sensors that rely on photoresistors. This function is fully digital.

Principle of the Radar Breathing Presence Sensor and Its Naming

The core detection component of our radar sensor is the 24G millimeter-wave radar. Coupled with our exclusive computational algorithms, it can precisely detect the expansion and contraction of the chest during human respiration, thereby accurately determining the presence of an individual within a space. This capability enables more precise and intelligent scene settings, which is the basis for its designation as a breathing presence sensor.

Inability of Infrared Motion Sensors to Detect Breathing Presence

Infrared sensors function by detecting moving heat sources. The subtle chest movements associated with breathing are insufficient to trigger an infrared sensor.

产品定义、功能、应用等方面介绍

60GHz康养雷达是什么？

60GHz康养雷达是一种基于毫米波技术的非接触式人体监测传感器。它通过发射60GHz高频电磁波并分析人体反射的微动信号（如呼吸、心跳和肢体活动），实现精准的跌倒监测、存在检测和人体姿态分析，专为健康护理、智慧养老和医疗监护等场景设计。

60GHz频段相比其他频段（如24GHz）有何优势？

相比24GHz等其他频段，60GHz具有三大核心优势：1.60GHz频段带宽更宽，分辨率更高，可检测更微小的动作（如呼吸）;2且此频段干扰少，适合多人场景;3.更强的穿透能力，可透过轻薄遮挡物检测人体状态。

60GHz传感器在功能和使用体验上，相比传统监测方式（如智能手表、传统监控）有哪些独特优势？

60G 传感器除检测呼吸存在外，还能非接触式监测心率，以及实现跌倒监测。无需像传统方式（如智能手表）需穿戴设备，且避免了传统监控的隐私困扰，比如老人在浴室跌倒，安装的它可检测并上报，既便捷又保护隐私。

60GHz传感器是如何检测跌倒的？误报率如何？

60G传感器通过探测房间中的微动信号，形成点云图像，通过算法搭建模型识别和区分出人的不同姿态，比如是否跌倒。然后把跌倒信号，通过有线或者无线的通讯方式通知给智能中控系统，进行是否报警联动的动作，或者直接通过APP的提醒消息通知给用户；60G跌倒探测准确率在96%以上。
