Tutorial: Deploy and walk through the water quality monitoring application
Traditional water quality monitoring relies on manual sampling techniques and field laboratory analysis, which is time consuming and costly. By remotely monitoring water quality in real-time, water quality issues can be managed before citizens are affected. Moreover, with advanced analytics, water utilities, and environmental agencies can act on early warnings on potential water quality issues and plan on water treatment in advance.
The water quality monitoring application template helps you kickstart your IoT solution development and enable water utilities to digitally monitor water quality in smart cities.
Devices and connectivity (1,2)
Water management solutions use smart water devices such as flow meters, water quality monitors, smart valves, leak detectors.
Devices in smart water solutions may connect through low-power wide area networks (LPWAN) or through a third-party network operator. For these types of devices, use the Azure IoT Central Device Bridge to send your device data to your IoT application in Azure IoT Central. You can also use an IP capable device gateway that connects directly to your IoT Central application.
When you build an IoT solution, Azure IoT Central simplifies the build process and helps to reduce the burden and costs of IoT management, operations, and development. You can brand, customize, and integrate your solution with third-party services.
When you connect your smart water devices to IoT Central, the application provides device command and control, monitoring and alerting, a user interface with built-in RBAC, configurable dashboards, and extensibility options.
Extensibility and integrations (3,4)
You can extend your IoT application in IoT Central and optionally:
- Transform and integrate your IoT data for advanced analytics, for example training machine learning models, through continuous data export from IoT Central application.
- Automate workflows in other systems by triggering actions using Power Automate or webhooks from IoT Central application.
- Programatically access your IoT application in IoT Central through IoT Central APIs.
Business applications (5)
You can use IoT data to power various business applications within a water utility. In your IoT Central water consumption monitoring application you can configure rules and actions, and set them to create alerts in Connected Field Service. Configure Power Automate in IoT Central rules to automate workflows across applications and services. Additionally, based on service activities in Connected Field Service, information can be sent back to Azure IoT Central.

Walk through the application
The following sections walk you through the key features of the application:
After you create the application, the Wide World water quality dashboard pane opens.
As a builder, you can create and customize views on the dashboard for use by operators. But before you try to customize, first explore the dashboard.
All data shown in the dashboard is based on simulated device data, which is discussed in the next section.
The dashboard includes the following kinds of tiles:
Wide World water utility image tile: The first tile in the upper-left corner of the dashboard is an image that shows the fictitious utility named Wide World. You can customize the tile to use your own image, or you can remove the tile.
Average pH KPI tiles: KPI tiles like Average pH in the last 30 minutes are at the top of the dashboard pane. You can customize KPI tiles and set each to a different type and time range.
Water monitoring area map: Azure IoT Central uses Azure Maps, which you can directly set in your application to show device location. You can also map location information from your application to your device and then use Azure Maps to show the information on a map. Hover over the map and try the controls.
Average pH distribution heat-map chart: You can select different visualization charts to show device telemetry in the way that is most appropriate for your application.
Critical quality indicators line chart: You can visualize device telemetry plotted as a line chart over a time range.
Concentration of chemical agents bar chart: You can visualize device telemetry in a bar chart.
Reset sensors parameters tile: The dashboard includes a tile for actions that an operator can initiate directly from the monitoring dashboard. Resetting a device's properties is an example of such actions.
Property list tiles: The dashboard has multiple property tiles that represent threshold information, device health information, and maintenance information.
Customize the dashboard
As a builder, you can customize views on the dashboard for use by operators.
Select Edit to customize the Wide World water quality dashboard pane. You can customize the dashboard by selecting commands on the Edit menu. After the dashboard is in edit mode, you can add new tiles, or you can configure the existing files.
Select + New to create a new dashboard that you can configure. You can have multiple dashboards and can navigate among them from the dashboard menu.
Explore a water quality monitoring device template
A device template in Azure IoT Central defines the capabilities of a device. Available capabilities are telemetry, properties, and commands. As a builder, you can define device templates in Azure IoT Central that represent the capabilities of the connected devices. You can also create simulated devices to test your device template and application.
The water quality monitoring application you created comes with a water quality monitoring device template.
To view the device template:
- Select Device templates on the leftmost pane of your application in Azure IoT Central.
- From the list of device templates, select Water Quality Monitor to open that device template.
