Hello @nantes.vanwyk,
Welcome to the DigiKey TechForum.
Yes, the Arduino Opta is a good candidate for your application. Let me add a few thoughts:
-
Consider Arduino’s cloud services
-
Consider adding OPTA’s Analog module to the Opta WiFi for the 4-20 mA input signals
-
Consider the material we have prepared for the Arduino Opta.
Best wishes,
APDahlen
