## Description

Product Document: https://wiki.wit-motion.com/english (1) WT901 Inclinometer TTL version gyroscope is a good solution for angle measurement, acceleration measurement and angle speed measurement. 3-axis gyro and 3-axis accelerometer, 3-axis magnetic. (2) Kalman filters combine gyro and accelerometer for high precision angle measurements. Can be used for 4-axis flight control, self-balancing robot, angle measurement, depth measurement, etc. (3) The module can get accurate posture in a dynamic environment. The posture measurement accuracy is 0.05 degrees. (4) Using high precision gyro accelerometer MPU9250 to read measurement data in serial port and IIC port. Advanced digital filtration technology reduces measurement noise and improves measurement accuracy (5) Use the small case, quality assurance, you can install it on your board. Key Features: 1 Input Voltage: 3V-6V 2 Current Consumption: Typical 20mA 3 Volumes: 36mm X 51mm X 15mm 4. Measuring: Posture angle: 3-axis, Acceleration: 3-axis, Angle speed: 3-axis magnetic 5 Range: Acceleration: ±0.6 oz (16 g), Angle Speed: ±2000°/sec. 6 Data output frequency reaches 200Hz. 7 Data Interface: Serial port UART (TTL level), I2C 8 Baud Rate (Baud Rate 2400-921600kps 9600kps). 9 Provides single chip analysis sample code. 10 GPS Connectivity Allowable according to NMEA-0183 standard GPS data. 11 4-way expansion ports for analog input and digital input and output Note: The angle of the Z axis is accurate to add magnetic field correction. Not affected by magnetics. Package Contents (1) 1 x WT901 Inclinometer TTL Version Gyroscope

## Questions & Answers

**Q: Does this work with srs studio + dof reality and the varjo aero headset?**
A: hello
Not for srs studio + dof reality and varjo aero headphones

**Q: where can I find arduino sample code?**
A: Hello sir, 
Thanks for reaching out and letting me know the concern. 
The WT901C RS232 is RS232 interface which will requires a RS232 to TTL module if you wanna connect this sensor with Arduino. 

Its sample code link as below:
