60GHz mmWave Sensor - Human Resting Breathing and Heartbeat Module

The MR60BHA1 60GHz radar module applies FMCW detected theory to implement simultaneous personal breathing rate and heart rate detention in high accuracy, providing a fully total private and secure environment, independently from other noisy influences. It is a standard biotic radar system in consumer electronics, healthcare as well as industrial applications.

PRODUCT DETAILS

Note

  • This sensor radar is for respiratory heartbeat detection, designed for normal resting heart rate for adults ranges from 60 to 100 beats per minute, i.e. the test range is under 100 beats per minute. As for test, the average person's heart rate is around 80 beats.
  • Because the detection mechanism is Frequency Modulated Continuous Wave mechanism, theoretically there will be no interference of the same frequency. However, it is highly recommended to have at least 1m installation spacing that radar sensor does not face each other, to avoid interference.

Note

  • The LED on the module has been removed.

Feature

  • Enabled theory: Implement radar detection based on FMCW FM continuous wave signals
  • Standard algorithm: Sense and output simultaneously human respiratory rate and heart rhythm in the self-adaption environment
  • Perfect privacy protection: Apply FMCW monitoring technology to provide surveillance capabilities without identification
  • Health-friendly working status: Output power as low as harmless to the human body
  • High stability: Independ from temperature, humidity, noise, airflow, dust, light, and other environmental influences
  • High measured accuracy: Achieve heartbeat accuracy up to 85% and achieve breathing accuracy up to 90 %
  • High flexibility hardware design radar: Support secondary development, adapt to various scenarios applications

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 I\O 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.
