This sensor measures 3-axis angle, angular velocity, acceleration, magnetic field. Its strength lies in the algorithm which can calculate three-axis angle (Attitude angles) accurately. The module has 3 aix gyro, 3 axis accelerometer, 3 axis magnetometer compass, pressure sensor for altitude. All these sensors are integrated for accurate attitude and heading angles measurements using advanced kalman filter algorithm.
HWT9053-TTL's interface is TTL , but its protocol is 485 communication.
Features
- Output TTL .
- Input Voltage: 5 - 36V.
- The attitude measurement accuracy up to 0.05°.
- IP67 level protection
- aluminum casing for magnetic interference and shock resistance
- Stable performance over long time with excellent noise suppression and temperature compensation.
