Description:
The Grove Doppler Radar Module is powered by the BGT24LTR11 Silicon Germanium MMIC, a 24GHz radar transceiver, and is driven by an XMC1302 MCU based on Arm® Cortex®-M0. Its compact design ensures low power consumption while delivering high-precision measurements.
The high-frequency radar enables exceptional penetration through objects, allowing it to be deployed behind surfaces, making it ideal for security systems. This module operates effectively in harsh environments, including extreme temperatures, dust, and rain, providing reliable proximity sensing and motion detection even in challenging conditions
