IoT Pro
Tilt Module
Industrial-grade tilt and orientation monitoring module for detecting lid opening, structural inclination, and asset movement, designed for long-term deployment in underground, outdoor, and critical infrastructure environments, and built on the IoT Pro hardware architecture.
Product Code: IOTPRO-TILT-MODULE
Product Overview
The IoT Pro Tilt Module is a precision tilt and orientation monitoring device designed to detect angular changes, movement, and positional deviations of fixed assets over time.
The module integrates a high-accuracy tri-axial MEMS accelerometer, calibrated to measure tilt relative to the gravity vector. This enables reliable detection of events such as lid opening, unauthorised access, structural leaning, or gradual displacement, without relying on mechanical switches or moving parts.
From a system architecture perspective, the device functions as a tilt and tamper acquisition node, providing deterministic, low-power, and long-term monitoring for assets where physical access is limited and reliability is critical.
The IoT Pro Tilt Module is particularly suited to infrastructure, utility, and municipal deployments, where early detection of movement or access events improves safety, reduces manual inspections, and supports regulatory compliance.
Typical Installation Points
The IoT Pro Tilt Module is typically installed on fixed assets where changes in orientation or position indicate access, tampering, or structural risk.
Horizontal Assets (Lid & Cover Monitoring)
In these installations, the module detects opening, closing, or partial displacement of lids based on angular change.
Fibre Access Chambers
Unauthorized access / Asset protection
Borehole Covers
Safety Monitoring / Maintenance Tracking
Utility Vault Lids
Security Alerting / Service Verification
Drainage Manholes
Unauthorized Entry Detection / Prevent Contamination
Fuel Tank Lids
Tamper Detection / Safety Compliance
Vertical Assets (Structural Tilt Monitoring)
In these applications, the module enables early detection of leaning, gradual movement, or impact-related displacement, supporting preventive maintenance and risk mitigation.

Measurement & Sensing Capabilities
The IoT Pro Tilt Module focuses on high-reliability orientation sensing, optimised for static assets where small angular changes are meaningful.
Integrated Tilt & Orientation Measurement
The built-in tilt sensor continuously measures orientation relative to gravity, enabling detection of:
-
Opening and closing of lids or covers
-
Changes in asset inclination or lean
-
Unauthorised movement or tampering
-
Gradual structural displacement over time
Tilt data can be analysed to distinguish between normal operational movement and abnormal or unauthorised events, supporting accurate event classification in critical infrastructure deployments.
