Smart Lighting
Precise sensing—say goodbye to “ineffective lighting.” At the heart of radar’s application in lighting is intelligent interconnection—a system that, by sensing the movement of people and objects, enables automatic control of lighting: lights turn on when someone enters the room and turn off when they leave. Essentially, this endows lighting with a “sensing brain.”
Smart Security
At the heart of radar’s application in camera-based security systems lies “precise triggering and range-based alerting.” It endows cameras with “long-distance sensing capabilities,” addressing the pain points of traditional cameras—such as “blind-spot imaging” and “post-event retrospective analysis”—and enabling proactive security through “preemptive warnings and precise capture during events.”
Smart Home Appliances
By using radar to detect the presence, distance, movement trajectories, and even subtle movements (such as breathing) of humans or objects, home appliances can “understand” the environmental conditions. For example, an air conditioner can sense prolonged absence of occupants and automatically reduce power consumption or shut down; a refrigerator can recognize when a user approaches and automatically light up the screen; and a range hood can be activated with a wave of the hand and adjust its fan speed accordingly. These features not only enhance the interaction experience but also make appliances more energy-efficient.
Smart Home
Without requiring image capture, radar can precisely detect the presence, location, and movements of people—and even subtle vital signs such as breathing and heart rate—while safeguarding privacy and penetrating non-metallic obstructions. It enables automated control that ensures devices start up when a person enters the room and automatically enter energy-saving mode when the person leaves. Additionally, it supports natural interactions like gesture-based controls and offers enhanced safety through features such as fall detection and alerts for unusual intrusions. Ultimately, this technology makes home environments more convenient, comfortable, secure, and low-carbon.
Automotive ADAS
In smart vehicle applications, radar serves as the “eyes” for environmental perception. By precisely detecting the position, speed, distance, and motion trajectories of surrounding objects—such as vehicles, pedestrians, and obstacles—it provides critical data support for autonomous driving decision-making and driving safety.

The 5.8GHz FMCW respiration and ranging radar sensing solution of Airtouch Technology helps accurate human presence perception!
Release time:
2022-04-30 15:57
With the rapid development of smart lighting, smart home, smart home appliances, smart security, etc., people's requirements for human body detection are also increasing. From motion detection, micro-motion detection, and now breathing detection, more chip solutions have also been proposed. high demands. It is necessary to effectively detect the presence of human body information, and to avoid false triggering interference of curtains, vegetation, and fans as much as possible, and also need more accurate distance information and a larger detection range.
01
Advantages Of The Airtouch FMCW Solution
Airtouch Technology has innovatively launched a 5.8GHz microwave radar FMCW (Frequency Modulated Continuous Wave) solution, which can achieve:：
The ranging function of the human body in the state of motion.
Lifebeing detection with ranging
function.
The 5820 breathing version chip of Airtouch Technology has excellent radio frequency performance and built-in high-performance MCU, which can effectively extract the weak signals of the human body such as breathing, chest expansion, and slight shaking.
The advantage of the 5.8GHz FMCW presence detection scheme of Airtouch Technology over high-frequency radar is that it has a larger coverage area and fewer human sensors can be deployed in the same space. At the same time, compared with the traditional 5.8G CW (continuous wave) presence detection scheme, it provides distance information, which can better avoid false trigger interference outside the range.

Implementation Principle
Principle of ranging
Frequency Modulated Continuous Wave (FMCW) refers to the emission of a continuous signal with a certain bandwidth and a linear change in frequency. This kind of signal is called a Chirp signal. FMCW can test distance, speed, etc.
Principle of motion detection
By detecting the amplitude of signal change at different times, when the degree of change exceeds a threshold and is within a given distance, it is determined that a moving target exists.
Principle of micro-moving detection
Anti-jamming filtering is performed on the signal, and based on the FMCW distance unit, the phase/amplitude change degree with time is counted for each distance unit. If the change degree exceeds the threshold, it is determined that the micro-moving target exists.
Principles of breath detection
By accumulating the signals of a given distance unit for a long time (several seconds to tens of seconds), the slow signal changes are extracted, and when the signal characteristics match the characteristics of human breathing (such as 12-20 times per minute, etc.), it is determined to be breathing exist.
