Grove - Doppler Radar (BGT24LTR11) (24GHz Transceiver) _MAKE_ROBO The classic Arduino Uno hasThe Doppler Radar is a compact and low power all in one sensor (Distance, Motion, Velocity and Angle Detection) based on the BGT24LTR11 Silicon Germanium MMIC, a 24GHz radar transceiver, and driven by the XMC1302 MCU with an Arm Cortex M0 core. It is compatible with Arduino (With a Grove Base Shield) and Raspberry Pi (Only with the Grove Base HAT) Its high frequency allows it to penetrate through objects, meaning it can be installed behind surfaces
