Water Leakage Monitoring System Using ESP32 and MQTT

Components:

• ESP32 microcontroller
• Water sensor
• MQTT Broker
• Smartphone or computer for displaying notifications

Steps:

1. Hardware Wiring:

• Connect the water sensor to the GPIO pins of the ESP32 as per the sensor manufacturer's instructions.

2. ESP32 Code:

• Write ESP32 code that performs the following:
  • Initializes the water sensor.
  • Connects to the MQTT broker.
  • Monitors the water sensor and publishes an MQTT message when a leak is detected.

3. MQTT Broker Setup:

• Create a free account on an MQTT broker such as CloudMQTT or HiveMQ.
• Create a new topic, e.g., water_leak.

4. MQTT Topic Subscription:

• On your smartphone or computer, create an application that subscribes to MQTT messages.
• Subscribe to the topic water_leak.

5. System Testing:

• Place the water sensor near a potential leak location.
• Simulate a leak by pouring water onto the sensor.
• Observe the MQTT application receive a notification.

Additional Features:

• Data Logging: Store water sensor readings on the ESP32 or external memory.
• Local Alerting: Connect the ESP32 to a buzzer or LED to trigger a local alarm when a leak is detected.
• Web Interface: Create a web interface to monitor the leak system and configure settings remotely.
