Senceive FlatMesh Wireless Monitoring

Senceive FlatMesh is a self-organising wireless mesh network for structural and geotechnical monitoring, supporting tilt nodes (single-axis, biaxial and triaxial), nano-strain gauges, crack meters, vibration sensors and environmental nodes. Each node is battery-powered (typical 8-15 year life on internal lithium battery), transmits via 868 MHz radio mesh to a gateway, and reports to the WebMonitor cloud platform with configurable alarm thresholds. The system is widely used on rail, infrastructure and heritage building monitoring projects across the UK and Australia, and is well-suited to engagements where running cabled instrumentation is impractical or visually unacceptable.

TRSC Application Commentary

TRSC specifies Senceive FlatMesh wireless tilt nodes when conventional cabled tiltmeter installations are impractical — typically on heritage facades where visible cabling would compromise heritage approvals, on rail-corridor monitoring where access to the asset is restricted to short maintenance windows, or on post-disaster sites where the time-to-deploy must be minimised. The principal advantages over cabled systems are speed of installation (a node and gateway pair can be operational in 1-2 hours), no cable runs to manage or maintain, and 8-15 year battery life that eliminates power-supply failure as a cause of monitoring downtime. The principal limitations are radio coverage (which must be tested at the proposed gateway location before specifying the system), measurement frequency (typical schedules are hourly or every 15 minutes — sub-second sampling is not the use case for FlatMesh), and reliance on cellular telemetry from the gateway to the cloud (which TRSC verifies with site signal-strength testing). Deployment workflow: TRSC specifies the node array, Senceive's certified installer (or TRSC personnel under Senceive training) installs the nodes, the WebMonitor cloud account is set up with TRSC engineering review of all alarm thresholds, and TRSC provides monthly review of the data with quarterly RPEQ-signed monitoring reports. The system is used on selected TRSC heritage and infrastructure monitoring engagements where the deployment constraints favour wireless over cabled instrumentation. Senceive's WebMonitor cloud platform also supports stakeholder reporting to multiple parties — useful on rail-corridor projects where the asset owner (typically a state rail agency), the principal contractor and the heritage authority all need parallel visibility of the same monitoring data, which TRSC has used to streamline approval and acceptance reporting on multi-stakeholder construction-phase engagements.

Frequently Asked Questions

Application questions about Senceive FlatMesh Wireless Monitoring

Why does TRSC use Senceive FlatMesh instead of cabled Geokon instrumentation?
When the deployment constraints favour wireless: heritage facades where visible cabling is unacceptable, rail corridors with limited access windows, or post-disaster sites where time-to-deploy is critical. For long-term high-precision engagements with available cable routes and on-site logger location, cabled Geokon instrumentation remains TRSC default. The choice is made per project against the access, visibility, and precision requirements.
Is the 8-15 year battery life realistic in Australian field conditions?
Yes for typical hourly or 15-minute reporting schedules, on the standard Senceive node hardware. High-frequency reporting (e.g. 1-minute or sub-minute) reduces battery life proportionally. TRSC's standard monitoring specification is 15-minute reporting with alarm-driven escalation to higher-frequency reporting if a threshold is approached, which preserves long-term battery economics.
How are alarm thresholds set?
TRSC engineering review establishes the threshold envelope from the structural assessment, with two-tier thresholds typical: 'attention' threshold triggers higher-frequency reporting and TRSC engineering review; 'action' threshold triggers immediate site attendance and stakeholder notification. Thresholds are documented in the monitoring plan and reviewed at each quarterly RPEQ-signed monitoring report.
