LoRa Technology Enables Structural Health Monitoring System for Smart Buildings

Enterprise IoT solutions provider for fiber and wireless sensing, Polysense Technologies, is using Semtech’s LoRa technology for its Structure Health Monitoring (SHM) system. The integration would enable Polysense to perform remote and real-time monitoring of building structure safety and integrity.

With LoRa-based wireless sensors and gateways, Polysense can get a building connected within a couple of hours by eliminating the need for power wiring installation. In comparison, a wired solution which could take around a week to install. The key is to utilize the power of IoT to solve real problems. With their SHM solution, resource issues are properly addressed, while, most importantly, providing urgent information to protect citizens from danger. LoRa Technology, according to Polysense, is a perfect marriage for sensing and data analytics solutions.

The Polysense SHM system consists of various LoRa-based IoT sensors, a LoRa-based gateway, and a proprietary Cloud-based data management platform. A four to six-story building is equipped with an end-to-end solution consisting of several sensors on the walls and roof to measure building surface wall crack growth, tilt and vibration, and often a soil moisture sensor to monitor water saturation at the building’s foundation, at a fractional cost of the traditional wired solution or human inspection.

Typically, one gateway is used per residential complex. Additionally, Polysense provides the LoRaWAN-based network and mobile applications for real-time monitoring of building status. The company recently partnered with AEIDO, a Chinese company offering structural safety inspections, certification, and monitoring services, to roll out hundreds of SHM systems in Shaoxing, a city on China’s east coast which is particularly vulnerable to the elements.

Semtech’s LoRa Technology offers flexibility and easy deployment into a wide range of infrastructure, both old and new. Scalable by increasing the number of gateways, solutions built on LoRa Technology can cover the tallest skyscrapers and sprawling campuses. LoRa is a widely adopted long-range, low-power solution for IoT that gives telecom companies, IoT application makers and system integrators the feature set necessary to deploy low-cost, interoperable IoT networks, gateways, sensors, module products, and IoT services worldwide. IoT networks based on the LoRaWAN specification have been deployed in 100 countries and Semtech is a founding member of the LoRa Alliance, the fastest growing IoT Alliance for Low Power Wide Area Network applications.
