Introduction: Flood Warning Systems - Water Levels + IoT Sensor Monitoring Guide

About: I love remotely monitoring Industrial IoT / IIoT sensors. My favorite things is water monitoring systems, water levels / well telemetry, and flood warning systems. Questions? Please don't hesitate to get in t…

Do you need to monitor water levels?

You'll learn how to make water level monitoring systems in this tutorial.

These Industrial IoT devices are deployed as flood warning systems in the USA.

To keep you and your community safe, Smart Cities need to monitor storm surge, water levels, and rising tides.

Take a solid gander at the photo with the breakdown of the components you'll need to make each of your kit packages for flood monitoring systems:

  • Body of Water that You Need to Monitor Levels of!
  • Sensor Hub
  • Water Level Sensor
  • 4-20mA Sensor Adapter
  • GPS Sensor
  • Voltage Sensor
  • Solar Charge Controller
  • Solar Panel
  • Sealed Lead Acid (SLA) Battery
  • Power Converter

Step 1: Set Up Your Flood Monitoring Box

Put your components into a weatherproof box.

Drill holes and install cable glands on the bottom of your flood monitoring unit.

Attach the cables and wiring to your sensors and solar charge converter. You can use any brand of solar charge converter. You're seeing Morningstar solar charge converters in these pictures of flood warning systems deployed in the US.

Use your USB cables to connect your sensor hubs, 4-20 mA sensor adapters, and volt sensors.

Use a voltage converter to convert 12V from the solar charge controller to 5V for your sensor hub.

Step 2: Configure Your Water Level Sensor

Set up your Water Level Sensor and attach it to your 4-20mA sensor adapter.

You can use level sensors made by any sensor hardware manufacturer, like Flowline or Senix.

Use cable wire gauge thickness that makes sense for your application. Be sure it's sturdy, durable, and long lasting.

Step 3: Fire It Up

Lights on!

Connect power to your system to make sure you've got all of the components correctly connected.

Configure your sensor hub to send your sensor information to

You see Sealed Lead Acid (SLA) 12V batteries used in these flood warning systems deployed in Virginia, East Coast USA. Your batteries can be from any manufacturer like Duracell.

Step 4: Get Ready for Your Field Deployment

Set up and fine tune your flood warning system to finalize it for deployment in the field.

Get ready to get your boots dirty after you've got your solar panels and other hardware ready to drop at your deployment location.

There are guides like this for the solar panel tilt you should use. Use your solar panel mounting kit to adjust your angle to what's appropriate for your solar panel environment.

Step 5: Deploy Your Flood Monitoring Systems

Use poles, fence posts, walls, bridges, or anything else you need to securely mount your flood warning systems.

Remember to double check that your solar panel is facing south if you're in the northern hemisphere. And that it's facing north if you're in the southern hemisphere. :) You can purchase your solar panels and solar mounting kits from various manufacturers like Renogy.

You can deploy your flood warning systems anywhere. Please don't hesitate to contact me if you need any advice or have any questions.

Step 6: Remotely Monitor Your Water Levels With Flood Warning Systems and Industrial IoT Sensors

You've successfully deployed your flood warning systems in the field.

That's it. These are simple, rapidly deployable monitoring systems compared to some other remote monitoring systems.

Congratulations. Way to go!

Now your water level information is uploaded as often as you configured on your account.

You can see your water sensor information on maps, graphs, tables, and configure custom alerts for when the water levels go too high or low. You can also use web dashboards to quickly see what's going on in the field with multiple water level systems with IoT sensors.
