This is our first project in Node Red. We start to look at more industrial applications using 4-20mA signals for level measurement sensor, in this example we use a Siemens SITRANS LR110. This project also uses a Sequent MicroSystems IO card with a Raspberry PI. This last video adds additional functionality for alarms, with a user interface, e-mail notifications and connectivity to InfluxDB.
