Smart Water Monitoring System

This smart water monitoring system is designed for environments without Wi-Fi infrastructure. Using just two simple wires, it accurately detects humidity levels or water leakage and sends real-time alerts via LTE or NB-IoT using the MQTT protocol through a cloud-based MQTT broker (e.g., Adafruit, Amazon, or a customer-owned broker).

The system seamlessly integrates with and automatically controls shut-off valves, such as the smart water actuator, which subscribes to MQTT messages sent by the monitoring system. It operates in two modes:

• Automatic watering mode: ideal for plant irrigation.
• Automatic shut-off mode: activates in case of spills or significant water leakage.

This makes it perfect for remote, self-sustaining buildings and agricultural applications in isolated areas where Wi-Fi is unavailable but long-range connectivity (e.g., LTE) is present.

System Benefits:

• Monitoring of autonomous, self-sustaining buildings and infrastructure.
• Operates almost anywhere with LTE-M/NB-IoT network coverage.
• Solar power/rechargeable battery enables self-contained operation.
• Detects high/low moisture levels or water spillage.
• Allows users to control water valves via the MQTT broker.
• Fully compatible with the smart water actuator.
