Arduino Opta: Scalable Automation Made Simple
Arduino Opta makes industrial and building automation more accessible than ever. This compact yet powerful micro PLC integrates seamlessly with existing machines, systems, and production lines and works effortlessly with the broader Arduino ecosystem: from smart sensor modules to gateways and SOMs, enabling complete, end-to-end automation solutions tailored to your needs.
Built to last. Built for scale.
Designed with security and durability in mind, Opta supports over the air firmware updates and ensures end-to-end data protection with a built in secure element and X.509 compliance.
Smarter manufacturing, powered by Opta
Use Opta alongside load cells or vision systems to streamline manufacturing flow ensuring packaging is accurate and time stamped using NTP synchronization. Monitor processes in real-time via Bluetooth® Low Energy, local HMI, or remotely through Arduino Cloud dashboards. Predict issues before they happen using built in machine learning for anomaly detection and preventive maintenance.
Smart Buildings, Smarter Control
From roller blinds and sun shields to HVAC, irrigation, and electrical systems everything in a building can be intelligently connected and automated. Whether based on simple triggers like time and day, or on complex data from air quality sensors, weather forecasts, and energy usage patterns, Arduino Opta enables efficient, remote control of all systems.
