WitMotion SINAT-485 Dual-Axis Inclinometer Digital Angle Sensor, RS485, 0.2° Accuracy, IP68 Waterproof, 5–36 V, 0.0055°/LSB

Overview

WitMotion SINAT-485 is an industrial-grade, dual-axis digital angle sensor that measures X and Y inclination with 0.2° angular accuracy. It communicates over RS485, operates from 5–36 V, and features a rugged IP68 waterproof enclosure (supports working in water for up to 30 min). A built-in dynamic fusion + Kalman filtering algorithm delivers stable, low-noise output. Free PC software (MiniIMU.exe) provides real-time visualization, logging (TXT/CSV/Play/BIN), and 3D demos, with multi-device connections up to 128 units.

Key features
