Accelerometer Sensor 3-5V GY-BMI160 6DOF 6-Axis Gyro Gravity

Accelerometer Sensor 3-5V GY-BMI160 6DOF 6-Axis Gyro Gravity

The BMI160 module from Bosch Sensortec is a highly integrated 6-axis MEMS inertial sensor that combines a 3-axis 16-bit accelerometer and an ultra-low-power 3-axis gyroscope into a single compact package. Designed for low-power motion-sensing applications, this module is ideal for smartphones, tablets, wearables, and fitness devices. It supports high-precision motion tracking, step counting, tilt detection, and gesture recognition, with extremely low power consumption—even in full-speed operation.

Package Includes:

  • 1 x BMI160 6-Axis IMU Sensor Module

Sample Arduino Code (I2C):


#include <Wire.h>
#include <Seeed_BMI160.h>

BMI160 bmi160;

void setup() {
  Serial.begin(115200);
  if (bmi160.initialize() != BMI160_OK) {
    Serial.println("BMI160 init failed!");
    while (1);
  }
  Serial.println("BMI160 initialized");
}

void loop() {
  bmi160.getMotion6();
  Serial.print("Accel: ");
  Serial.print(bmi160.ax); Serial.print(" ");
  Serial.print(bmi160.ay); Serial.print(" ");
  Serial.print(bmi160.az); Serial.print(" | Gyro: ");
  Serial.print(bmi160.gx); Serial.print(" ");
  Serial.print(bmi160.gy); Serial.print(" ");
  Serial.println(bmi160.gz);
  delay(500);
