Accelerometer Sensor

WT901BLECL Accelerometer 

Accelerometer + Magnetometer + Gyroscope

  • 【Output data】3-axis acceleration, 3-axis angular velocity, 3-axis magnetic field, 3-axis angle and quaternion accelerometer.
  • 【Core Advantages】The WT901BLECL inclinometer integrates an attitude solver, which, in conjunction with the dynamic Kalman filter algorithm, therefore can accurately output the current attitude of the module in a dynamic environment. The accelerometer sensor measurement accuracy is 0.2°, the stability is extremely high, and the performance is even better than some professional inclinometers.
  • 【Technical advantages】Solved the cumulative error caused by the drift of gyroscope integration in the 6-axis algorithm.
  • 【Output frequency】The output content can be selected arbitrarily, data output frequency: 0.2Hz~200Hz, 50Hz~200Hz data package transmission, default 10HZ.
  • 【Production process】The inclinometer sensor module uses 4-layer PCB board process, thinner, smaller and more reliable.
  • 【Ble 5.0】Bluetooth 5.0: The Bluetooth accelerometer  support Android /IOS operating system and the maximum distance can reach 90 meters.
  • 【chip】The accelerometer sensor equip with a 168MHZ high-performance cortex-M4 core.
  • 【Current and baud rate】Operating current: ≈ 16mA, and standby current 14uA-16uA and Data interface: baud rate 115200.
  • 【Compact size】 32.5mm*23.5mm*11.4mm small size, therefore it easy to use in various scenarios.
  • 【You will get】WT9011DCL inclinometer*1, Type-C Charging cable*1, and Quick Start Guide*1.
  • 【 Worry-free Support 】12-month warranty, and lifetime friendly customer service.

Is this sensor an Inertial Sensor?

Our Attitude Sensors are all Inertial Sensors (IMU). The angle output uses an intrinsic Euler Angle coordinate system with the ZYX rotation sequence.

What is the Euler Angle rotation sequence, and what is the corresponding Quaternion order?

The Euler Angle rotation sequence is ZYX (intrinsic rotation). The Quaternion order q0, q1, q2, q3 corresponds to w, x, y, z.

Why does the Bluetooth connection disconnect when the distance exceeds 8 meters?

The Bluetooth module used in our product is rated for a 50-meter Transmission Range. Our Transmission Range tests were conducted in an open area without signal interference from other devices or physical obstructions. In actual use, interference from other devices and physical obstacles can affect the Bluetooth Transmission Range. The receiving device also plays a role. Please refer to the actual environment for real-world performance. Suggestions: First, reduce other signal interference, such as Wi-Fi 2.4GHz signals, which can affect Bluetooth. Second, avoid obstructions like walls and the human body; do not transmit through solid objects. Third, use a high-performance Bluetooth receiving device.

Why do the Quaternion Output, Magnetic field, and battery data show no change at 200Hz?

The WT901BLECL uses the Bluetooth 5.0 protocol, which has a limited payload length. The active output protocol only includes Acceleration, angular velocity, and Angle data. Other data, such as quaternion, magnetic field, and battery status, must be read by sending commands from the PC software or the mobile APP, and are not actively transmitted by the sensor. When the Output rate is at 200Hz, the sensor only outputs the default parameters. It cannot respond to other read commands in time, which results in no change in quaternion, magnetic field, and battery data on the PC software or the mobile APP.

What do the Bluetooth LED indicators mean?

When charging during power-on: The red light stays on, and turns off after fully charged. During power-on operation: The blue light flashes rapidly when connecting, and flashes slowly after successful connection. When powered off: No light. In abnormal cases, the red light is on while charging, but the blue light does not turn on when powering on, or no light turns on at all.
