Real-time monitoring and alerting for soil moisture levels

Purpose

1. Real-time monitoring and alerting for soil moisture levels automates detection, reporting, and notification of critical dryness or overwatering in crop fields, enabling rapid responses to environmental changes, optimal irrigation scheduling, prevention of crop stress, data-driven yield increases, and minimizing water waste.

Trigger Conditions

1. Periodic retrieval of sensor data via IoT devices or gateway APIs.

2. Threshold exceeded: Soil moisture below or above predefined limits.

3. Time-based triggers (e.g., hourly, per minute).

4. Manual/remote sensor recalibration or validation request via API.
