This board features Infineon’s 60GHz XENSIV™ radar sensorBGT60LTR11AIP(configured in Autonomous mode). The BGT60LTR11AIP MMIC is a fully integrated microwave motion sensor including Antennas in Package (AIP), built-in motion and direction of motion detector and a state machine allowing fully autonomous operation of the MMIC without any external microcontroller. An integrated frequency divider with a Phase-Locked Loop (PLL) provides VCO frequency stabilization. These features make the small-sized radar solution a compelling, smart, and cost-effective replacement for conventional passive infrared (PIR) sensors in low-power or battery powered applications. The MMIC is designed to operate as a Doppler motion sensor in the 60GHz ISM-band. For this board, since the MMIC is for autonomous operation, it only requires power supply and ground via two pins and directly provides the digital output regarding detected motion and direction of motion via two other pins. It is designed in a way that it directly fits on an Arduino MKR board.
