Underground Structures

Tunnels.

Measure convergence, vault settlement, and lining stress deep underground, with cabled sensors linked to the surface.

We bypass legacy constraints to deliver absolute operational clarity.

Zero Cellular Signal

Wireless signals do not reach deep tunnels, so sensors are cabled to a gateway that sends the data from the surface.

High Humidity & Dust

Underground conditions are harsh, so the sensors need sealed IP65 enclosures.

Vault Convergence

During excavation, millimetre changes in tunnel shape can warn of a collapse.

Hybrid Gateway Architecture

By utilizing a serial RS485 bus, dozens of tiltmeters and displacement sensors can be daisy-chained deep underground and connected to a single Asense 4G Gateway situated at the tunnel portal, ensuring continuous data flow without cellular coverage.
