Smart Irrigation System with ESP32

Project Overview

This project involves creating a smart irrigation system using an ESP32 microcontroller. The system utilizes various sensors and actuators to manage irrigation based on real-time data and user-defined settings. The ESP32 is connected to Firebase for remote monitoring and control.

Components

• ESP32 Microcontroller: Main control unit.
• WiFiManager Library: Manages WiFi connections.
• FirebaseESP32 Library: Handles Firebase interactions.
• Various sensors and actuators: Includes water level sensors, rain sensors, and more.

Sensors and Actuators

Water Level Sensor

• Pin: A0
• Description: Measures the water level in the reservoir. The analog value is read to determine the water level status (LOW, MEDIUM, HIGH).

Rain Sensor

• Pin: 27
• Description: Detects rain. When the rain is detected, it sends a digital signal indicating HIGH (rain detected) or LOW (no rain).

Soil Moisture Sensor

• Pin: A3
• Description: Measures soil moisture percentage. This sensor helps in determining if irrigation is needed based on soil moisture levels.

Flotteur Sensor

• Pin: A0 (shared with Water Level Sensor)
• Description: Additional water level detection; ensure this pin is correctly managed if used for multiple purposes.

Relay

• Pin: 19
• Description: Controls the irrigation pump. When activated, it turns the pump ON or OFF based on the system's requirements.

Firebase Configuration

• Firebase Host: iot-irrigation-smart-default-rtdb.firebaseio.com
• Firebase Auth: AIzaSyCba_eDDCMY7-vQREAOJY4w_DQB1_PB28A

Time Configuration

• NTP Server: pool.ntp.org
• GMT Offset: 3600 seconds (1 hour)
• Daylight Offset: 0 seconds

Firebase Paths

• System Status: /Status_du_system/status
• Rain Sensor Status: /System_irrigation_smart/Captuer_de_pluie/status
• Irrigation Mode: /Mode/status
• Water Level Sensor Status: /System_irrigation_smart/capteur_niveau_eau/status
• Soil Moisture: /System_irrigation_smart/humidite_du_sol/value
• Humidity Agriculturist Value: /humiditer_agriculteur/status
• Pump History ON: /Historique/historiquePompeOn
• Pump History OFF: /Historique/historiquePompeOff
• Water Level Sensor History: /Historique/historiqueCapteurdeWaterlevel
• Rain Sensor History: /Historique/historiqueCapteurDEPLUIE
• Pump History: /Historique/historiquePompe
• Pump Status: /System_irrigation_smart/pompe/status

Setup and Configuration

1. Install Required Libraries: Ensure you have the WiFiManager, WiFi, FirebaseESP32, and Wire libraries installed in your Arduino IDE.
2. Connect to WiFi: The ESP32 will attempt to connect to the WiFi network specified by ssid and password.
3. Configure Firebase: Replace FIREBASE_HOST and FIREBASE_AUTH with your Firebase project details.

Usage

• Manual Mode: The system can be controlled manually through Firebase. Adjust water levels and pump status as needed.
• Automatic Mode: The system will automatically manage irrigation based on sensor data and pre-defined thresholds.

Troubleshooting

• Connection Issues: Ensure WiFi credentials are correct and check for network connectivity.
• Sensor Calibration: Verify sensor readings and calibrate if necessary.
