Product catalog summary
Introduction
The LoRaWAN LWHD-WM400 is a long-distance wireless triaxial inclinometer designed for structural health monitoring (SHM). It features ultra-low power consumption, with a battery life of up to 10 years under specific conditions. The device supports data transmission through the LoRaWAN G500 gateway and can connect to TTN or Chirpstack and APP servers.

Main Features
  • Accuracy of 0.005° and resolution of 0.001°.
  • Triaxial tilt measurement with a range of ±60°.
  • Operates in temperatures from -40°C to +85°C.
  • Supports both horizontal and vertical installation.
  • Includes a dual switch design with an external magnetic switch and built-in toggle switch.
  • Can connect to Android devices via OTG USB Type-C for configuration and data reading.
  • Built-in ROM can store up to 60,000 data sets.

Applications
  • Monitoring dangerous housing and bridge tower inclinations.
  • Dam and slope disaster prevention.
  • Protection monitoring for ancient buildings.
  • Tunnel and foundation pit monitoring.
  • Tower tilt monitoring.

Technical Specifications
  • Power voltage: 3.6VDC~5VDC with a peak working current of 100mA.
  • Stand-by current is 4μA.
  • Communication distance up to 15km.
  • Protection level: IP68.
  • Shell material: Magnesium aluminum alloy anodizing.
  • Installation with four M6 screws.

Installation Guidelines
Proper installation is crucial to avoid measurement errors. The sensor must be mounted flush with the measured surface, which should be level. The sensor's bottom line should be parallel or orthogonal to the measured object's axis.

Certifications and Standards
  • ISO9001:2015, CE, and ROHS certified.
  • Complies with various GBT and GJB standards for reliability, environmental testing, and electromagnetic compatibility.

Packing List
  • LWHD-WM400 unit, EVE ER34615 battery, optional NdFeB magnetic screws, radome, and antennas.
  • Includes an aviation plug-USB power and data cable, and OTG USB Type-A to Type-C cable.

LoRaWAN Series Long-distance wireless triaxial inclinometer The correct installation method can avoid measurement errors. The following points should be done when installing the sensor: First of all, ake sure that the sensor mounting surface is completely close to the measured surface, and the measured surface should be as level as possible, and there should be no included angles as shown in Figure A and Figure C. The correct installation method is shown in Figure B and Figure D. uneven surface generates the i angle Secondly, the bottom line of the sensor and the axis of the measured object cannot...
