WitMotion SINVT Dual-Axis Inclinometer, 0–5V Analog ±90°, RS232/RS485, 9–36V Supply, IP67 Industrial Attitude Sensor

Overview

WitMotion SINVT is a compact, low-cost voltage-type inclination sensor that measures X/Y dual-axis tilt (±90°) and outputs standard 0–5 V analog (center 2.5 V at 0°). Built on high-precision MEMS with an integrated Kalman filter, it delivers stable angle data in dynamic conditions. The module supports serial communication (RS232/RS485 optional) for configuration and alarm setting via PC software, operates from 9–36 V DC, and is housed to IP67 for harsh environments.
