Seeed Studio Studio Grove Doppler Radar (BGT24LTR11) - 24GHz Motion & Velocity Sensor Module
The Seeed Studio Studio Grove Doppler Radar (BGT24LTR11) is a 24GHz microwave motion and velocity sensor module compatible with 3.3V/5V systems like Arduino and Raspberry Pi via UART. It provides precise detection of moving objects, speed measurement, and angle detection, even when concealed behind non-metallic surfaces.
Features
- 24GHz Doppler radar transceiver (BGT24LTR11 MMIC) for precise motion and velocity sensing.
- Arm Cortex-M0 (XMC1302 MCU) provides onboard signal processing and UART communication.
- Operates from 3.3V to 5V DC, making it compatible with Arduino, Raspberry Pi, and other microcontrollers.
- High-frequency penetration allows deployment behind enclosures for discreet security and automation.
- Robust performance in harsh environmental conditions including dust, rain, and variable lighting.

The Grove Doppler Radar leverages a 24GHz Silicon Germanium MMIC (BGT24LTR11) paired with an XMC1302 Arm Cortex-M0 microcontroller to deliver advanced motion sensing capabilities. Unlike traditional PIR or ultrasonic sensors, it uses continuous-wave Doppler radar to detect not only presence but also the radial velocity and angle of moving objects with high precision. The electromagnetic signal penetrates non-metallic materials, enabling concealed installation for security and automation systems.
This module outputs processed data via a UART interface at 115200 baud, providing object detection, speed, and directional information with a 300ms update rate. Its compact, low-power design is engineered for reliability in industrial robotics, smart building access control, and UAV applications, maintaining stable operation across a wide temperature range and adverse weather conditions.
