⚡ Executive Technical Takeaways (TL;DR)
  • ➔ MQTT with QoS 1 guarantees reliable plant metric delivery even over noisy, high-interference industrial Wi-Fi environments.
  • ➔ Compact ESP32 controllers and Modbus gateways digitalize legacy machines without replacing existing heavy machinery.
  • ➔ Time-series databases (TimescaleDB) power predictive failure analytics with sub-second aggregate query speeds.

Full architectural guide to capture industrial sensor telemetry (temperature, vibration, pressure) using ESP32/PLCs, MQTT brokers, and reactive dashboards.

Architectural Frequently Asked Questions

Can legacy machines without Ethernet or digital ports be integrated?

Yes. We employ non-invasive hardware sensing (clamp-on split-core CT current sensors, magnetic vibration probes, and surface thermocouples) connected to our edge gateways without altering machine internal wiring.

How is data security enforced across factory telemetry streams?

All MQTT traffic runs over TLS/SSL encryption with x509 mutual certificate authentication or encrypted bearer tokens, isolated within an air-gapped industrial VLAN.
