DFRobot Gravity SEN0692 6DOF IMU Sensor
DFRobot Gravity SEN0692 6DOF Inertial Measurement Unit (IMU) Sensor is a plug-and-play motion sensing module built around the Bosch BMI323. The device combines a 3-axis accelerometer and a 3-axis gyroscope to measure acceleration, angular velocity, tilt, vibration, and changes in motion. The sensor supports measurement ranges up to ±16g and ±2000°/s, with output data rates reaching 6400Hz for accurate motion tracking and gesture detection.
Designed for rapid prototyping, the DFRobot SEN0692 features I2C and UART interfaces, Gravity-compatible connectivity, and operation from 3.3V to 5V systems. Built-in hardware functions support step counting, tap detection, tilt sensing, free-fall detection, and activity recognition, reducing processor workload. A 2048-byte FIFO buffer and GUI visualization software simplify development, making the sensor ideal for robotics, wearable devices, interactive electronics, game controllers, and motion-aware Internet of Things (IoT) applications.
