WitMotion SINDT Dual-Axis AHRS Inclinometer Tilt Sensor, Accelerometer+Gyro+Quaternion, 0.05° XY, 0–±90°, 200 Hz, IP67, RS232/RS485/TTL

Overview

WitMotion SINDT is an industrial dual-axis tilt sensor / AHRS inclinometer built around an MPU6050 IMU with a built-in Kalman fusion algorithm. It measures X- and Y-axis angles while outputting 3-axis acceleration, angular velocity, magnetic/quaternion attitude data. The unit uses an aluminum housing with IP67 sealing and ships with free PC software for configuration, visualization and logging. Designed for long-term deployment in harsh environments, it supports TTL/RS232/RS485 (CAN optional) interfaces and a wide 5–36 V supply.
