Radar range
- The radar coverage range is a three-dimensional fan-shaped area with a horizontal angle of 40 ° and a vertical angle of 40 °.
- Due to the influence of radar beam characteristics, the radar has a relatively long operating distance in the normal direction of the antenna surface, but the operating distance will be shorter if it deviates from the normal direction of the antenna.
- When the radar is installed at an angle, the radar's operating range will be reduced due to the influence of the radar beam range and effective radiation space, and attention should be paid when using it.
Function Introduction
- Motion Detection: Can detect human movements, such as walking, small hand movements, etc.
- Respiratory detection: It can detect small movements such as chest heaviness caused by human respiration.
- Collection of respiratory heart rate: It can calculate the respiratory and heart rate values of the human body per minute.
- Sleep Monitoring: It can evaluate sleep quality, record sleep time, and monitor in/out of bed status.
Application Scenario
- Home: Can be used for health monitoring of the elderly and children, as well as sleep quality assessment of family members.
- Hotel: Can be used for intelligent management of guest rooms and provide personalized sleep services.
- Hospital: Can be used for postoperative monitoring, rehabilitation monitoring, and diagnosis and treatment of sleep disorders in patients.
- Nursing Home: Can be used for health monitoring, fall warning, and sleep quality assessment of the elderly.
Product Advantages
- Adopting millimeter wave radar technology, it has the characteristics of non-contact measurement, high-precision measurement, powerful functions, and easy installation.
- can be widely used in homes, hotels, hospitals, nursing homes and other places, providing efficient and accurate solutions for personnel health monitoring, sleep quality assessment, elderly care and other scenarios.
Due to the limitation of the radar antenna beam range and deviation from the normal direction of the radar, the effective operating distance will be reduced. Millimeter wave electromagnetic waves have certain penetration characteristics for non-metallic materials, and can penetrate common glass, wooden boards, screens, and thin partition walls, detecting moving objects behind obstructions; But it cannot penetrate thicker load-bearing walls, metal doors, etc.Precautions
- Startup time: When starting to work after initial power on, it is necessary to completely reset the internal circuit and fully evaluate the environmental noise to ensure the normal operation of the equipment. Therefore, when the device is initially powered on, it needs to have a stable startup time of ≥ 60 seconds to ensure the effectiveness of subsequent output parameters.
- Due to the limitations of the respiratory and heartbeat detection scenario, the radar is a non-contact device. To detect the respiratory and heartbeat of a target, the position of the target needs to be locked first, and then the respiratory and heartbeat intensity and values of the target need to be collected and calculated. Therefore, it is required to detect the target within a reasonable detection range, maintain a resting state for detection, and avoid continuous movement affecting the radar's locking of the target, thereby affecting the detection of respiration and heartbeat.
- Effective detection distance. The detection distance of radar equipment is closely related to the target and environmental factors. The effective detection distance may change with changes in the environment and target. This device currently does not have ranging function, so fluctuations in the effective detection distance within a certain range are normal phenomena.
- Radar biological detection performance, due to the fact that human biological characteristics belong to ultra-low frequency and weak reflection characteristic signals, radar processing requires relatively long time accumulation processing. During the accumulation process, many factors may affect radar parameters, so occasional detection failures are a normal phenomenon.
