Monitoring water quality in real-time is a very important use case for the industrial internet of things (I IoT). By connecting pH and/or ORP electrodes to the Interstack’s packs below (sensors not included), water quality information can be monitored, intelligently processed locally, and sent in real-time to any on-premise, or cloud platform, including the Interstacks MyStacks visualization dashboard. Data can be sent using wifi, ethernet, or via the cell data network. The packs below include a Superbase, I/O ph ORP block, and a communications block. The I/O pH ORP block also includes an input for a water flow sensor and two switched relay outputs for controlling valves.
