Respiration and heartbeat detection radar finished product human presence non-contact

The finished product of respiratory and heartbeat detection radar is a non-contact respiratory and heart rate vital signs detection radar in the human body. The vital signs parameters are an important manifestation of human health. Real-time detection of vital signs signals has great research value. Currently, the vital sign detection devices on the market are not only about price. The volume is difficult to meet the requirements of ordinary users, and the device itself is also limited by cable connections. Most of the traditional traditional detection methods require sensors to contact the human body, such as electrocardiogram (ECG) photoplethysmography (PPG) and pressure-sensitive pulse sensors.

The finished product of breathing and heartbeat detection radar for vital signs detection does not need to contact the human body, is not easily affected by the surrounding environment, and has good permeability. It has strong anti-interference ability and provides non-contact for cardiopulmonary activity monitoring in fields such as health monitoring. miniaturization. Portable solutions to make portable medical. Real-time health monitoring at home and outdoors is possible. Let Doppler biological non-contact breathing heart rate vital signs detection radar have a wide range of applications in clinical detection, medical detection and sleep monitoring of sleep-disordered breathing, as well as baby care.

With the development and popularization of smart terminals, physical sign signal processing and feedback based on mobile platforms have begun to be applied in the field of medical signal processing. The radar sensor design has the function of collecting vital sign information. The information collected by the radar is transmitted to the intelligent mobile terminal through the WiFi module. The digital signal processing is replaced by the computer or embedded system by the dynamic terminal. The finished product of the respiration and heartbeat detection radar realizes the real-time calculation and display of the heart rate and respiration. storage to form a complete vital signs monitoring system.

Radar actually judges static or dynamic objects by emitting electromagnetic waves of different frequencies and wavelengths. The principle is that the transmitter of the radar device emits electromagnetic wave energy to a certain direction in space through the antenna, and the radar antenna receives the reflected wave and sends it to the receiving device to extract the distance, distance change rate or radial velocity, direction, height from the target object to the radar. and other information.

The reflected wavelength varies with the parameters of the object. If the object is stationary, the wavelength is fixed. When encountering a moving object, the wavelength changes. The change in wavelength is related to the direction of the moving object. When away from the emitting device, the wavelength of the reflected wave is higher than the wavelength of the wave source, and the frequency is lower.

The finished product of respiration and heartbeat detection radar uses the Doppler principle to transmit high-frequency electromagnetic waves through the antenna, receive and process the reflected waves, judge the movement of objects within the coverage area, and give corresponding electrical signals. It is a small and complete radar system with integrated transceiver antenna and low power consumption. It can sense the motion state of objects in a closed space and accurately measure the distance between objects.

With radar chip as the core, it is a vital sign monitoring solution suitable for indoor scenes. It can monitor vital signs such as breathing/heart rate all day long, and has the characteristics of real-time monitoring and instant feedback. In addition to remote measurement, the scheme also has the advantages of high precision and high precision. It can detect the micro-motion and breathing signals of the human body, and realize the detection of living bodies under the motion and static state of the human body. It truly realizes presence sensing, and is also widely used in smart lighting, smart security, smart sensor switches, smart bathrooms, smart homes and other fields.

Human Presence Non-Contact Respiration Heart Rate Radar Product It can detect human presence within a set distance. From lighting and security equipment, anything within the range of smart homes and smart buildings can tell if human sensing is close enough and trigger an action.

Micro-motions of breathing can be detected and reacted even when the user is still. With this micro-motion detection capability, the solution has become ideal for intuitive user interaction with the device. Therefore, users do not need to wave their hands in front of the sensor to react to the device.
