Industrial IoT and condition monitoring with NB-IoT

Industrial environments have seen IoT pilots for the better part of a decade. But moving those pilots into production presents a different challenge: connectivity that works in a demo conference-room can fail in the field, and a vendor that seems suitable in a presentation may face tougher scrutiny when a regulator asks where its chip is manufactured. This guide explains why NB-IoT is the right wireless technology for many industrial IoT deployments, especially condition monitoring, predictive maintenance and asset visibility, and why the ST87M01 is built to address the constraints that production-grade industrial designs face.

Three problems that block industrial NB-IoT projects

1. Network reach in hard-reach locations
   Industrial sites are built around concrete and steel structures, with significant electrical noise. The areas where condition data matters most: pump rooms, heat exchangers, motor control centers, equipment yards, distribution cabinets. These are also the places where standard cellular signals struggle. NB-IoT's deep-indoor link budget and narrow-channel robustness are well suited to this environment.
2. Integration complexity
   An industrial sensor node typically combines a sensing element, a low-power microcontroller, a power management circuit and the wireless module. Each interface is a point where firmware engineering and certification effort add up. A module that comes with a complete embedded protocol stack and a mature MCU integration library can significantly reduce that effort.
3. Supply-chain stability over a long lifecycle
   Industrial designs are specified, qualified and deployed over horizons measured in years, not quarters. The supplier's longevity commitment, fabrication footprint and ownership of the supply chain are no longer purely procurement concerns: they are engineering risk concerns, and they show up in formal supplier audits.

Use cases

• Condition monitoring: vibration, temperature and pressure on pumps, motors, compressors and HVAC systems, with NB-IoT carrying low-rate telemetry and exception alerts.
• Predictive maintenance: trend data from rotating equipment that lets maintenance teams act before failure, not after.
• Tool and equipment tracking: movable industrial assets across a campus, with optional GNSS positioning on the ST87M01-1301 and ST87M01-2301 variants.
• Safety and alarm devices: lone-worker alarms, perimeter sensors and emergency notification across large or remote sites.
• Distributed factory monitoring: outdoor and remote-edge locations on a factory site where wired connectivity is impractical or too costly to retrofit.

Why ST87M01 for industrial designs

Industrial-grade by specification
With an operating temperature range of -40 °C to +85 °C, conducted RF power up to +23 dBm, and an immunity profile aligned with the EN 301 489 family, the ST87M01 is designed for real industrial environments rather than laboratory conditions presented as industrial use cases with cybersecurity certified at the module level.
The RED-DA cybersecurity requirement applies to all radio equipment placed on the European market from 2025. The ST87M01 is RED-DA certified, which removes the device-level cybersecurity test campaign that would otherwise sit on the integrator's project plan.

A fully European-controlled supply chain
ST owns the SoC, the RF front-end and the module design end-to-end. The module is designed and manufactured in Europe. For buyers operating under regulated supplier-vetting regimes, including critical infrastructure, defense-adjacent industrials and any operator under a sovereignty mandate, this is now an entry criterion, not a differentiator.

Embedded protocol stack and developer ecosystem
IPv4/IPv6, TCP/UDP, CoAP, LwM2M, MQTT, HTTP/HTTPS and DTLS run on the module. The ST87 Easy Connect library, with C examples, gets a connected sensor application onto a host MCU in days rather than weeks.

Fifteen-year longevity commitment
The ST87M01 is part of the 15-year product longevity program. Industrial designs that must navigate regulatory and procurement cycles without unplanned redesigns benefit directly from this commitment.

Integrating NB-IoT into an industrial design

• Always-OFF: an external MCU wakes the ST87M01 on a sensor event or a scheduled interval. Lowest BOM, ideal for periodic-report condition-monitoring nodes.
• Always-ON, highest efficiency: two LDOs (one always on, one enabled in transmit only) maximize efficiency for nodes that need fast responsiveness.

Both topologies are documented in the ST87M01 product folder, with reference schematics and BOM guidance.
