Product Description

bluetooth accelerometer acceleration sensor gyroscope gyro magnetometer mpu6050 mpu9250 inclinometer

Highlights

HWT905’s scientific name is AHRS IMU sensor. A sensor measures 3-axis angle, angular velocity, acceleration and magnetic field. HWT905 is employed where the highest measurement accuracy is required. Its strength lies in the algorithm which can calculate three-axis angle accurately.

  • Robust MEMS designs and high performance in harsh environment
  • Ground breaking bias stability, low noise level and good vibration robustness
  • Persued for best data accuracy and stability: WTMOTION patented zero-bias automatic detection calibration algorithm and R&D dynamic fusion algorithm outperforms traditional accelerometer sensor

Technical Specifications:

  • Current: <40mA
  • Voltage: 5-36V (requiring a power source of 5-36V)
  • Interface: Modbus RTU
  • Baud Rate: 4800-230400 (adjustable)
  • Working Temperature: -40℃ ~ +85℃
  • Output Content: 3-axis Acceleration+Angle+Angular Velocity+Magnetic Field+Quaternion
  • Range: Acceleration (±6g), Gyroscope (±2000°/s), Magnet Field (±4900µT), Angle (X, Z-axis: ±180°, Y ±90°)
  • Resolution: Acceleration (0.005g), Gyroscope (0.61°/s), Magnet Field (16 bits)
  • Angle Accuracy(after calibrated): X, Y-axis: 0.05° (Static) , X, Y-axis: 0.1° (Dynamic)

Note: Z-axis angle will be affected by magnetic field. It is required to calibrate and keep the sensor at least 20cm away from the stuff like metal that may create magnetic field interference.
