1. INTRODUCTION
The MM5D91-00 is the presence detection sensor module which integrates 60GHz
mmWave technology. The module simplifies the implementation of mmWave sensors in
the band of 61.0 to 61.5GHz, and it includes the ARM Cortex-M4F based processor
system, 1Tx 3Rx antenna and onboard regulator. This presence detection sensor module
targets low power and high resolution presence detection in smart home, office, security
and diverse applications.
Based on the MM5D91-00 Radar sensor module, the MM5D91E00 evaluation board is
built to demonstrate the function of presence detection of the 60 GHz radar sensor with
its sophisticated radar presence detection algorithms.
