MR60FDA1 60GHz mmWave Sensor - Fall Detection Pro Module | FMCW, Sync Sense, Privacy Protect, high stability, support secondary development

PRODUCT DETAILS

Note

• 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.
• We have provided upper computer for you to utilize radar directly. Enjoy it!

The 60GHz Fall Detection Module Pro mmWave sensor module, based on FMCW technology and self-algorithmic of the target's attitude parameters, through movement changes such as speed and distance, detects and continuously records the fall status of the target, and functions the alarm for abnormal stationary dwell, which is an ideal solution for private property surveillance, falling caution, and elderly health care.

Feature

• Enhanced detecting algorithm: Output simultaneously human activities including moving, falling, and stationary in the self-adaption environment
• High measured accuracy: Achieve fall detection accuracy ≥90% and achieve presence awareness function accuracy ≥90 %
• Privacy Protection: More secure identification than the vision-based devices, with no concern about privacy leakage
• High Immunity against Interferences: Independ on temperature, humidity, noise, airflow, dust, light, and other environmental influences
• Support Secondary Development: Adapt to various scenarios and applications

Description

The R60AFD1 radar module uses 60GHz mmWave radar technology to achieve the functions of human activity detection including moving, falling, and stationary. Based on the FMCW radar system and 1 transmit 3 receive (1T3R) antenna, the radar through the algorithm accurately scans the body tomography, achieving the fall detection function by height difference and speed change of the human body.

The module is suitable for top installation, and the detected area is a three-dimensional sector of 60° horizontally and 60° tilted and the measured distance is between 0.4-3 m.

The radar supports secondary development and it adapts to various scenarios and applications. Using a universal UART communication interface provides an extra common protocol as 4 groups of I/O are reserved by the user’s definition. It can also be equipped with a host computer to output detection status and data, and its several groups of GPIOs can be customized and developed by users.

Note:

1. The radar is designed to be used for individual (human body) in the environment, if there are multiple targets, it will affect the accuracy and precision of the radar.
2. The LED on the module has been removed.
3. The 60GHz radar baud rate is 115200.

Applications

• Elderly Care
• Home Security
• Smart Home

Pinout

Interface 1:

• The 5V pin is the power supply interface for the sensor.
• RX and TX are the data transmission interfaces for the sensor. RX means serial receive and TX means serial transmit.
• The human presence status output interface. You can use the level of these two pins to determine the current human movement in the environment.
  • GP2 output: high level - occupied, low level - unoccupied.
  • GP1 output: high level - active, low level - stationary.

Interface 2:

• Flash firmware pinout: GND/3.3V/SWD/SWC
• Overhead input/output pins: GP3~GP6.
