If you’re looking for a flexible, affordable way to control machines, monitor sensors, or build IoT‑ready automation systems, an ESP32‑based industrial controller could be the right choice.

Why the ESP32 is ideal for IoT

The ESP32 is a powerful, low‑power system‑on‑chip (SoC) from Espressif Systems. It offers built-in Wi‑Fi, Bluetooth, plenty of I/O options, and compatibility with popular frameworks such as the Arduino IDE or the ESP-IDF. That makes it a go-to for many developers building connected devices, from hobby projects to serious automation.

But while ESP32 shines in hobby and consumer electronics, typical industrial settings require more: rugged enclosures, isolation for I/O, reliable power supply, and EMI safety. That’s where industrial‑grade ESP32 controllers come in.

Enter industrial‑ready ESP32 controllers by NORVI

NORVI builds controllers that combine the flexibility of ESP32 with the durability and design‑requirements of industrial hardware. These devices are engineered for real‑world automation and IoT, with proper enclosures, DIN‑rail mounting, isolated I/O, and compliance with industrial standards.

Depending on your project, you can choose from different models:

  • Relay‑output controllers
  • 4–20 mA current sensor models
  • 0–10 V analog sensor models
  • Mixed I/O versions – analog + digital + relay or transistor outputs

Connectivity is another strong suit. Beyond Wi‑Fi and Bluetooth, NORVI controllers support:

  • RS‑485 (Modbus) for robust serial communication with legacy equipment
  • Ethernet for wired network integration
  • NB‑IoT, LoRa or cellular (depending on the series) – ideal for remote installations and long‑range connectivity

They also include user‑friendly touches: built-in display, front‑panel buttons, and support for multiple programming environments (Arduino IDE, ESP‑IDF). That helps developers get up and running quickly.

What you get, and why it matters

  • Cost-effective alternative to traditional PLCs. For many automation tasks, ESP32-based controllers deliver nearly the same capabilities at a lower cost.
  • Flexible I/O and expansion. Whether you need digital inputs, analog sensors, relays, or transistor outputs, and even extra modules, NORVI controllers handle it.
  • Protocol and connectivity versatility. Ethernet, Wi-Fi, RS‑485/Modbus, or wireless options like NB‑IoT/LoRa give you freedom to integrate with legacy equipment or modern cloud‑based systems.
  • Developer‑friendly customization. Thanks to open‑source toolchains, standard libraries, and flexible programming, you can tailor automation logic, data acquisition, remote monitoring or control according to your needs.

Ideal Use Cases

  • Industrial automation: motor control, valve operation, conveyor systems, and general process control.
  • Data acquisition and monitoring: sensor networks, environmental monitoring, energy usage tracking.
  • Remote or distributed installations: leveraging Ethernet, NB‑IoT, LoRa or cellular to control or monitor equipment from afar.
  • Smart building or infrastructure automation: lighting, HVAC, access control, and building management systems.
