Use case: Smart Irrigation on ThingsBoard Edge
Section titled “Use case: Smart Irrigation on ThingsBoard Edge”The Smart Irrigation solution template demonstrates the Scheduler in a practical remote deployment. It automates irrigation based on soil moisture sensor readings and predefined schedules, with ThingsBoard Edge running locally to ensure operation during network outages.
The solution:
- Irrigates fields twice a day at predefined times.
- Monitors soil moisture, daily water consumption, and irrigation duration in real-time.
- Operates locally on ThingsBoard Edge, independent of internet connectivity.
Install the solution template
Section titled “Install the solution template”Log in to the ThingsBoard Platform, go to Solution templates, scroll to the Smart Irrigation block, and click Install.
The template automatically creates an Edge instance and assigns all required configurations.
