Jorjin Technologies MM5D91-00 mmWave radar motion sensor module

The MM5D91-00, manufactured by Jorjin Technologies, is an integrated millimetre-wave (mmWave) radar-sensing solution based on Infineon’s XENSIV mmWave radar chip. The module enables engineers to rapidly deploy detecting and tracking capability of micro and macro motions with high sensitivity for developing next-generation smart home and building and healthcare applications.

Compared to traditional passive infrared and ultrasonic sensors, mmWave radar-sensing technology offers many performance benefits. Radar sensors do not require operation with a direct line of sight, making it possible to be concealed or disguised underneath plywood or plastic enclosures for addressing privacy and security considerations. Radar sensing is also adaptable to environmental conditions such as darkness, sunshine, smoke, fog or haze, which should reduce detection errors.

The all-in-one integrated solution enables the detection of human presence within a configurable range. Micro-movement detection like typing in front of a notebook and macro-movement detection like walking inside a room can be detected. Powered by Infineon’s XENSIV mmWave radar chip and its radar presence detection algorithms, the product incorporates a processor system based on Infineon’s ARM Cortex-M4F, an integrated 1Tx/3Rx antenna, and an onboard power regulator.

The antenna in package (AIP) with built-in detector feature makes it easy for engineers to integrate mmWave radar sensing capability, without prior technical know-how in radio frequency, antenna design or radar signal processing. The product offers low power consumption and a small form factor, and is FCC pre-test ready.
