Water Quality Monitoring With IoT Sensors

I love remotely monitoring Industrial IoT / IIoT sensors. My favorite things is water monitoring...

Intro: Water Quality Monitoring With IoT Sensors

How do You monitor water quality with IoT sensors?

You'll learn just how to do that in this Instructable!

We'll be showing you step-by-step how government organizations in the USA monitor sensor hardware made by George Fischer Signet, Yoctopuce, and other hardware manufacturers.

You can use Industrial IoT (Industrial Internet of Things) water quality sensors to measure and monitor any factors, like:

  • pH (Acidity)
  • Conductivity / Resistivity
  • Oxidation Reduction Potential (ORP)
  • Dissolved Oxygen (DO)

To get started with the monitoring systems you see in the photos and videos of this Instructable, you'll need at least the following equipment for each of your water quality monitoring systems:

Ready? Let's get started with how to make your water quality monitoring systems in the next step!

Step 1: Connect Your IoT Sensor Wires and Cables

1st off you'll make sure that you properly connect your IoT water quality sensors. The GF Signet water quality sensors output the international sensor standard 4-20mA signal.

You'll connect your water quality probe sensor to your yellow 4-20mA output box as seen in the photos and sensor documentation. You'll also connect the 4-20mA output connectors to your 4-20mA sensor adapters. In our demo the (1) labeled on the green output block is the positive out and connects to your 23V input channel on your 4-20mA sensor adapters. The connector labeled (3) goes from your GF Signet 4-20mA sensor output box to your 4-20mA sensor adapter signal input / infinity sign you see on the sensor adapter for Channel 1.

You'll need to supply 5V of micro USB power to your sensor adapters. The systems you see in the photos are deployed by county government agencies, water municipalities, and water management resources organizations in the U.S.

These systems connect to standard 110V mains power from a regular ol' wall power plug. The solar charge controller and voltage regulators in the box distribute power as needed to the various components and provide a UPS battery backup system.

The systems in the photos use the Verizon CDMA cell network to upload sensor information to Valarm Tools as often as you need it. You can use WiFi, GSM cell network, ethernet, long-range WiFi antennas, or any other internet connectivity that best fits your scenario.

Similarly with power sources, these systems are totally flexible, so if solar panel power works better than you can harness the power of our sun.

Step 2: Monitor Water Quality and Pollution Remotely

Now that you've got your water quality sensors properly wired up, you'll mounted and install them where you need them, e.g., in pipes, lakes, aquifers, rivers, streams, and other bodies of water you need to monitor.

After you connect your sensor hubs to the cloud you'll see your water quality sensor information on maps, graphs, and other analytical tools.

You can configure e-mail message alerting so you'll know when water quality is approaching a risky level.

This is your quick and easy tutorial to get you started with water quality monitoring using IoT sensors. We covered the most critical, tricky steps to get you going.

You can find tons of other incredibly useful Instructables that wonderfully cover solar panel power, working with 110V mains power plugs, more brands of water quality sensors made by various hardware manufacturers, and other things you may want to combine with your water quality monitoring boxes.
