IoT App to control and monitor remote PLC (Industruino)

This App is able to control your remote devices connected to Arduino over internet (using MQTT protocol).
We have tested with several MQTT server as broker like mosquitto, vernemq, cloudmqtt, hivemq etc. You can choose a server of your choice that follows MQTT should work the same.

The sensors and actuators configurations are read from a hosted configuration file that is in easily customisable JSON format.

The app creates the user interface Tab, Sensors and Controllers dynamically by reading the configuration file. The controller values can be adjusted from the UI dialogue box.

The actual Arduino devices used are as follows:
- Industruino D21G IND.I/O (https://industruino.com/)
- Industruino Ethernet Expansion Module
