Industrial IoT controller
A modular controller combining industrial interfaces, local storage, and flexible inputs and outputs.

The project
Support different sensors and communication links without redesigning the whole control platform.
Product highlights
- ESP32-WROOM-32UE platform with GSM, RS-485, and Ethernet connectivity.
- SD card storage, opto-isolated digital inputs, and relay / MOSFET outputs.
- Multiplexed I/O, Qwiic expansion, and backup-power provision.
How we approached it
Monitoring and control systems like the Industrial IoT controller run in places where networks drop and nobody is on site. We design for that first: local logging, safe default states and clear status reporting, built around ESP32-WROOM, Ethernet / RS-485.
Industrial interfaces, sensor wiring and power protection are specified before layout or firmware begins, and each link is tested under the conditions it will meet in the field. Remote access and updates are added only with a recovery path for devices that cannot be reached physically.
