WitMotion SINET Dual-Axis AHRS Tilt Inclinometer, 0.1° Accuracy, 0.01° Resolution, Alarm, RS232/RS485/TTL, IP67 (9–36V)

Overview

WitMotion SINET is a compact, industrial dual-axis AHRS inclinometer with a built-in tilt alarm. It measures X/Y tilt from 0 to ±90°, provides switching (voltage) alarm output with a configurable threshold (default 10°), and communicates via TTL/RS232 (RS485 optional per spec banner). The rugged aluminum alloy housing is IP67 sealed and survives high shock and vibration for outdoor machinery, vehicles, lifts, and antenna positioning. Power is a wide 9–36 V DC input.

Key Features

• Dual-axis tilt monitoring (X, Y), 0~±90°

• High precision: full-range ±0.1° accuracy; 0.01° resolution

• Fast response: up to 100 Hz (DC response)

• User-settable alarm threshold (default 10°); switch output, default level high (PC software adjustable)

• Wide supply: DC 9–36 V, typical 12/24 V

• Ruggedized: IP67, aluminum shell, anti-vibration 10 grms (10–1000 Hz), impact 3500 g/0.5 ms (3×/axis)

• Wide temperature: –40 … +85 °C operation

• Small size: 55 × 36.8 × 24 mm; four M4 mounting screws

• Quick start: 0.5 s power-on time

I/O & Wiring (color ↔ function)

1. Red — VCC (9–36 V)

2. Black — GND

3. Green — RX (device receives)

4. Yellow — TX (device transmits)

5. White — +X alarm output

6. Gray — –X alarm output

7. Blue — +Y alarm output

8. Brown — –Y alarm output

9. Purple — Relative-gesture zero; ground for ~2 s to set current posture to 0°

Interfaces: UART TTL or RS232 (ordering option). Alarm default output level is high (software-configurable).

Installation Notes

• Mount the sensor flat and rigid to avoid tilt errors; the mounting surface should be smooth/level.

• Keep the sensor axes parallel to the measured axes (see diagrams).

• May be installed horizontally or vertically (right-hand coordinate rule).

• Use the purple wire zeroing function to calibrate the current position to 0° after installation.

Typical Applications

• High-voltage line/pole monitoring

• Satellite & solar antenna positioning

• Aerial work platforms and vehicle leveling

• Medical equipment angle sensing

• Pan/Tilt mechanisms

• Hydraulic lifts

• General construction machinery angle control and tilt-based monitoring
