IoT Pro
The IoT Pro Hardware Architecture is a modular, industrial IoT device architecture designed, developed, and manufactured by IoT Solutions Ltd. It is built for long-term monitoring, sensing, and control applications where reliability, lifecycle stability, and software integration are critical.
Hardware Architecture
Key Architectural Highlights
Power-Intelligent, Long-Life Operation
Multi-year autonomous operation enabled by flexible power options, real-time power diagnostics, and built-in battery protection mechanisms designed for real-world deployments.
Integrator-First Software Architecture
A single, stable, fully backward-compatible integration protocol shared across all IoT Pro products. Firmware upgrades and new features never require software re-integration.
Long-Term Support & Architectural Stability
Hardware revisions, firmware, and integration interfaces are designed to remain supported for decades, protecting customer investments and large-scale deployments.
Field-Ready Deployment & Serviceability
Factory pre-configured devices activate on-site by removing a magnet. Modular electronics, replaceable batteries, and pluggable communication boards simplify installation, servicing, and long-term operation.
Built for Harsh Environments
Industrial-grade enclosure materials, double sealing, and high mechanical and environmental protection as a baseline — not an add-on.
Multi-Network by Design
LoRaWAN, NB-IoT, LTE Cat-1, Wi-Fi, and SIGFOX (Upon Request) supported within the same architecture, all using the same protocol and integration model.

Core Architectural Capabilities
Power Architecture & Energy Options
IoT Pro supports multiple power configurations to match different deployment constraints and maintenance strategies.
Power Intelligence & Battery Protection
IoT Pro is designed with the understanding that real-world battery life depends on behaviour, diagnostics, and recovery, not datasheets alone.
Devices include dedicated hardware that directly measures microampere-level current draw from the battery.
Detect abnormal power consumption
Diagnose battery-draining states
Automatically recover from malfunctions
Ensure it reaches it's expected lifetime
This capability is fundamental to reliable, long-term battery-powered IoT deployments.
Flexible Connectivity, One Integration Model
All communication technologies use the same IoT Pro protocol, ensuring that the network choice does not affect software integration.
This allows devices to operation on public networks, private LoRaWAN networks, and private Wi-Fi infrastructure without changing the integration model.
An optional industrial-grade GPS module can be added to any IoT Pro variant where location awareness is required.

The same hardware can be reconfigured, even in the field to support external SMA antennas, with multiple connector positions and antenna types. All options are fully documented in the public IoT Solutions Wiki
Material Options
Double sealing and pressure-equalised design enable IK10 and IP68 protection for harsh industrial and outdoor deployments.
UV-stable glass-fibre reinforced nylon for extreme outdoor or indoor environments
UV-stable glass-fibre reinforced polypropylene for outdoor or indoor environments with corrosive gases and liquids
Antenna Options
Four different external antenna types can be provided:

Short-angle antenna
Plastic through-the-lid (TTL)
Through-the-iid (TTL) antenna with acetal
Simplified Commissioning & Field Deployment
IoT Pro devices can be fully pre-configured at factory level, including network credentials and operational parameters.
In the field, commissioning can be as simple as:
-
Removing a magnet from the enclosure
-
Allowing the device to automatically activate, connect, and report
No mobile application, laptop, or manual configuration is required.
On-device LEDs provide immediate visual feedback during installation, while a Bluetooth mobile application allows technicians to access detailed diagnostics when needed.
This approach significantly reduces installation time, errors, and dependency on specialised personnel.
Remote Configuration & Lifecycle Control
Network parameters, sensor settings, and device behaviour can be configured remotely over the network.
IoT Solutions provides these lifecycle and configuration tools out of the box, with no licensing or subscription dependencies, enabling software integrators to:
-
Use them directly
-
Integrate selectively
-
Bypass them entirely and manage everything from their own platform
The same applies to firmware over-the-air (FOTA) updates.
No mobile application, laptop, or manual configuration is required.
This ensures maximum flexibility without forcing architectural or commercial dependencies.
Modularity, Serviceability
& Long-Term Support
IoT Pro hardware is designed to evolve without replacement:
-
Batteries are connector-based and easily replaceable
-
Communication technologies are implemented on pluggable boards
-
Core electronics remain stable across generations
Security, Integrity & Deployment Trust
IoT Pro hardware is designed with security, integrity, and predictable device behaviour as core architectural principles.
Rather than treating security as a software add-on, it is embedded across the hardware, firmware, and lifecycle management layers of the device to support long-term, trustworthy deployments.
Controlled and recoverable firmware updates
Predictable, backward-compatible device behaviour
Continuous monitoring of device health and integrity
These principles support deployment in industrial, regulated, and mission-critical environments.
Cyber Security by Design
Cyber security is addressed as a core architectural concern, focused on minimising attack surface and preventing unauthorised device behaviour throughout the device lifecycle.
Secure boot and firmware authenticity verification
Unique device identity for authentication and fleet trust
Controlled access to configuration and updates
Secure communication mechanisms for data in transit
Detection of abnormal operational behaviour
Together, these measures enable secure deployments without compromising device stability or maintainability.
Built for Software Integrators
At its core, IoT Pro is not just hardware.
It is an architecture designed to let software integrators build once, scale across applications, and trust that hardware reliability, power behaviour, firmware evolution, and field realities are handled by IoT Solutions Ltd.
While IoT Pro is built for long-term reliability and mission-critical deployments, the architecture is deliberately designed to remain cost-effective.
By combining multi-network support, long battery life, modular hardware, built-in health monitoring, and free lifecycle tooling, IoT Pro reduces total cost of ownership over the full deployment lifecycle not just the initial hardware cost.
Where This Architecture Is Used
IoT Pro Products
The IoT Pro Hardware Architecture is the foundation of all IoT Pro products, including energy monitoring, environmental sensing, level and distance monitoring, parking systems, generator monitoring, and marine applications.
