Why choose WITMOTION? The company is ISO9001-2015 and IATF16949 certified, which are international standards for automotive manufacturing. WITMOTION masters the manufacturing chain, utilizing MEMS technology, advanced algorithms, strict chip selection, and calibration equipment.

The WT901C is the AHRS IMU sensor from WITMOTION. It integrates a high-precision gyroscope, accelerometer, and geomagnetic field sensor, and uses a high-performance microprocessor, advanced dynamics fusion algorithm, and Kalman dynamic filtering algorithm to quickly analyze the module's current real-time motion posture.

Through its advanced digital filtering technology, the WT901C can effectively reduce measurement noise and improve measurement accuracy. With its built-in posture solver and dynamic Kalman filter algorithm, the sensor can accurately output the current posture of the product in a dynamic environment. The measurement accuracy of the X and Y-axis can reach 0.05°, with extremely high stability.

The WT901C features several technical specifications, including a current draw of less than 40mA, a voltage range of 3.3-5V, a data output frequency of 0.2-200Hz, and a baud rate of 4800-230400 (adjustable). It can measure acceleration (±6g), gyroscope (±2000°/s), magnetic field (±4900µT), and angle (X, Z-axis: ±180°, Y ±90°).

In terms of hardware, the WT901C is built with a highly-integrated MEMS accelerometer and gyroscope sensor, a premium power chip for stable supply voltage, a 4-layer PCB design, and a Cortex-M0 core processor. The sensor is housed in a plastic casing with a net weight of 20g and dimensions of 51.3mm x 36mm x 15mm.

The WITMOTION products are derived from aerospace satellite attitude determination algorithms, including an R&D dynamic fusion algorithm, Kalman filtering, digital filtering, and state estimation algorithm. This allows for time and energy savings, as users don't need to write a filtering program or study the complicated protocol of MPU6050/9250 to analyze and collect the attitude angle data.

WITMOTION provides a detailed communication protocol for data analysis and calculation, as well as diverse sample codes for 51 serial, C++, C#, STM32, Arduino, and Matlab to reduce the work and time spent on MCU programming.

The company also offers a comprehensive tutorial and development kit, including a manual with setup instructions, a datasheet, free software for Windows PC (Minimu.exe), an Android app, and instruction videos on YouTube. Additionally, the product comes with a 4-pin Dupont cable and an instruction card with QR codes for the document center.

WITMOTION's software offers several advantages over traditional sensors, including configuration settings, a dashboard with 3D demo, data curve and chart display in real-time, data recording and playback, and raw data reviewing. The 3D demo provides a more intuitive view of the sensor's motion state, and the source code can be provided if customers have specific needs.

Customers can easily set up and use the WT901C by following the instructions on the manual or video demo, wiring the USB-TTL serial converter cable, and installing the CH340 or CP2102 serial drivers. The real-time motion changes will be displayed on the data curve, and users can record and export the data to TXT format for further analysis.

The WITMOTION sensor can also be configured using the provided software or Android app, allowing users to easily adjust settings such as acceleration and magnetic field calibration, output rate, bandwidth, measurement range, and placement direction.

In addition to the Windows PC software, the WT901C supports serial connection with Android smartphones. Users can search for "WitMotion" on the Google Play Store, install the app, and easily set up the sensor by choosing the 9-axis series, selecting the corresponding COM port and baud rate, and starting to use the sensor.

WITMOTION has a dedicated R&D department with over 20 professional engineers and a long-term collaboration with the Beihang University PhD team. The company has a world-class testing and manufacturing facility, including a triaxial nonmagnetic turntable, high and low-temperature test chambers, vector network analyzers, and a 6-degree-of-freedom vibration test bench, ensuring the high performance and stability of their sensors.

WITMOTION offers a range of products, including the WT901C-TTL Tilt Angle Sensor, WT901C-232 Digital Compass, WT901C-485 Inclinometer, WT61C-TTL Gyroscope Sensor, WT61C-232 Accelerometer, and BWT901CL AHRS IMU. These sensors are compatible with Windows PC, Android smartphones, MCUs, Arduino, Raspberry Pi, and more, with various connectivity options such as TTL, RS232, RS485 Modbus RTU, and Bluetooth.

In summary, WITMOTION is a professional attitude measurement solution provider with a focus on delivering high-performance, robust, and reliable sensors. With their advanced algorithms, strict quality control, and comprehensive customer support, WITMOTION aims to become a global leader in the attitude sensor market.
