Highlights

HWT901B’s scientific name is AHRS IMU sensor. A sensor measures 3-axis angle, angular velocity, acceleration and magnetic field. HWT901B 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: 3.3-5V (requiring a power source of 3.3-5V)

Data output frequency:0.2-200Hz

Baud Rate: 4800-961200 (adjustable)

Working Temperature: -40℃ ~ +85℃

Output Content: 3-axis Acceleration+Angle+Angular Velocity+Magnetic Field+Quaternion+Air Pressure+Height

Range: Acceleration (±16g), Gyroscope (±2000°/s), Magnet Field (±4900µT), Angle (X, Z-axis: ±180°, Y ±90°), Barometer (1 axis)

    I'm using this in my car with an Android head unit that lacks its own compass. The RS-485 version is compatible with the car's 12 volt supply, and the unit could be placed far away but I found a close spot for it without too much magnetic interference. I learned its important to calibrate according to the instructions.

    I really like this product.  It is everything that is advertised.  The after sales service was terrific.  Kyle, the company representative held my hand and guided me for the successful operation of this product.  I actually could have done it my self since it was so simple but I was just too lazy and took advantage of the great support they give !
