3-axis tilt sensor EM320-TILT

XYZLoRaWANwireless

Overview
The Milesight Tilt Sensor EM320-TILT is a 3-axis inclinometer for precise angle measurement and movement detection based on inclination changes. It supports configurable threshold alarms, NFC-based configuration and long battery operation for a wide range of IoT and industrial monitoring applications.

Key Features

• Accurate 3-axis tilt measurement (X, Y, Z) for angle and inclination monitoring.
• High-resolution, stable MEMS accelerometer sensing.
• Flexible alarm configuration: up to 36 customizable triggers and relative initial position setting for simplified deployment.
• LoRaWAN® wireless communication compatible with standard gateways and network servers.
• IP67-rated enclosure for outdoor and harsh environments; multiple mounting options (wall, pole).
• NFC configuration for quick device on/off and parameter setup via mobile phone and Milesight ToolBox.
• Long battery life using two ER14505 Li-SOCl2 batteries with low-power LoRaWAN operation.

Flexible Settings

• Up to 36 Triggers: Supports up to 36 customized trigger alarms based on angle/inclination on X, Y and Z axes.
• Relative Initial Position: Define a custom initial reference to detect relative angle changes and ease installation.
• Threshold Alarm: Configurable alarms when angles/inclinations exceed set thresholds.

NFC Configuration & Workflow

• Wireless configuration and power on/off via NFC using the Milesight ToolBox mobile app.
• Typical NFC workflow: install Milesight ToolBox → enable NFC and attach phone to device → verify password and configure parameters.

Cloud & Software

• Integrates with Milesight IoT Cloud for data visualization, automated triggers, scheduled reports and real-time alerts. Supports Android & iOS management apps.

Applications

• Tree bending / tilt monitoring
• Barrier gate position and movement monitoring
• Cranes and construction machinery tilt/safety monitoring
• Structural and asset inclination monitoring for safety and predictive maintenance
