Overview
The EM320-TILT is a LoRaWAN tilt sensor for 3-axis angle measurement and asset movement detection. Its compact size and MEMS accelerometer allow easy installation on trees, poles, structures and equipment to monitor X, Y and Z tilt angles remotely.
A built-in MEMS accelerometer covers −90° to +90° on all three axes with ± 1° accuracy and 0.01° resolution, delivering stable and reliable inclination data over LoRaWAN.
Up to 36 customised trigger alarms can be set on X, Y and Z angles or inclinations. A relative initial position lets the sensor detect movement from the installed baseline rather than a fixed reference, simplifying setup.
An IP67 enclosure, anti-theft back cover and pole or wall mounting options suit demanding outdoor sites, from forestry and infrastructure to construction and barrier monitoring.
LoRaWAN Class A connectivity reaches up to 15 km line of sight, while two ER14505 batteries provide around four years of operation at a 10-minute reporting interval.
NFC configuration via the Milesight mobile app enables one-touch setup without opening the enclosure, with threshold alarms reported in real time through gateways and Milesight IoT Cloud.

Applications
The EM320-TILT tracks tree bending and lean angles to flag unstable trees before failure, helping protect people and property in parks, roadsides and managed forests.
Utility poles, streetlight columns and sign structures are monitored for gradual lean or sudden movement, with threshold alarms enabling preventive maintenance.
Installed on slopes and retaining structures, the sensor detects angle changes that may indicate ground movement, supporting early warning in geotechnical monitoring.
Cranes, construction machines and barrier gates benefit from tilt monitoring to verify stability and detect unauthorised movement or tampering in the field.
