60GHz Respiratory Heartbeat Sensor 生物心律雷達感測器 seeed原廠

Description

The MR60BHA1 60GHz radar module implements personal breathing rate and heart rate detection based on Frequency Modulation Continuous Wave(FMCW) detected theory, providing a fully private and secure environment, independently from other noisy influences. Additionally, with built-in a standard algorithm and onboard antenna, the unit ensures simultaneous signal output in high accuracy. It represents an ideal solution for high-accurate, self-regulation, privacy-protected, secure biotic radar systems in consumer electronics, healthcare as well as industrial applications.

Because the range resolution is heavily dependent on available bandwidth, 60 GHz mmWave sensors will offer significantly better performance than 24 GHz sensors for high-accuracy and reliable object identification. Meanwhile, 60 GHz mmWave sensors gather rich point-cloud data as it is critical to maintain high measurement accuracy for respiratory and heartbeat scenarios. As the radar works mainly on the basis of the respiratory heart rhythm causing undulating movements on the surface of the large muscles through 60 GHz mmWave, the undulation of the human chest and back will be more pronounced

The MR60BHA1 radar leverages the fine performance of 60 GHz FMCW and utilizes an intelligent processing algorithm to achieve the high-accuracy output, as 85% of heartbeat detection and 90% of breathing detection. Furthermore, the radar can be independent from temperature, humidity, noise, airflow, dust, light, and other environmental influences. Designed as low power output, the radar maintains health-friendly working status while it is observed. For privacy protection, the radar provides a perfect solution that applies FMCW monitoring technology to equip surveillance capabilities without identification.

The radar supports secondary development and it adapts to various scenarios applications. Using a universal UART communication interface provides an extra common protocol as 4 groups of IO that are reserved by the user’s definition. The detected area is a three-dimensional sector of 80° horizontally and 80° tilted and the measured distance is between 0.4-2 m.
