Sentinel sensor networks for real-time monitoring of infrastructure and ecosystems

Pitutsimaniq, a network in Inuktitut, captures the essence of this project, which aims to interconnect infrastructure monitoring systems for the well-being of northern communities. Rapid population growth and the demands of economic development are creating a significant need for new construction and renovations, while climate change and permafrost destabilization are taking their toll. Integrating environmental and infrastructure monitoring systems into smart networks will be a novel approach for early warning of damage risks, performance monitoring of existing adaptation measures, and the ability of public authorities to respond. Currently, monitoring tools operate in isolation, collecting data in scattered data loggers that are accessible at best a few times a year.

With northern communities and infrastructure owners needing real-time monitoring and integrated information, our core project aims to network low-cost sensors capable of reading, storing, and transmitting data under harsh climatic conditions while consuming minimal energy. Distributed network sensors along linear transportation infrastructure, covering the areas inhabited by communities, will detect heat sources that indicate soil settlement and damage. In the longer term, fiber optic sensors will be developed to measure soil thermal regimes, which are crucial for both the dynamics of transitioning ecosystems and the stability of infrastructure. These smart networks will also be compatible with the range of innovative sensors developed by other Sentinel North teams, thereby multiplying the program's creative value and providing researchers with greater insight into the impacts affecting the environment and human infrastructure.
