IoT-Irrigation-Data-Collection-System

This repository contains the Arduino firmware for an IoT-based data collection system, utilizing the ESP32 microcontroller, to measure:

  • Soil Moisture
  • Soil Temperature
  • Relative Humidity
  • Air Temperature
  • Rain Probability

The system is designed to collect real-time environmental data to enable smart irrigation and agricultural monitoring.

Features

  • Local Data Storage: Collected data is stored locally on an SD card for redundancy.
  • Cloud Integration: Data is transmitted to the ThingSpeak IoT platform for remote access and analysis.
  • Multi-Sensor Support:
    • Soil moisture and temperature data are collected using HW-390 and DS18B20 sensors, respectively.
    • Relative humidity and air temperature are collected using the AM2302 sensor.
    • Rain probability data is retrieved via the OpenWeatherMap API.
  • Low-Power Mode: The system leverages ESP32 deep sleep mode to optimize energy consumption.

Requirements

Hardware

  • ESP32 Microcontroller (Programmed using Arduino IDE)
  • HW-390 Soil Moisture Sensor
  • DS18B20 Temperature Sensor
  • AM2302 (DHT22) Humidity and Temperature Sensor
  • RTC Module (e.g., DS3231)
  • SD Card Module
  • Power Supply

Software

  • Arduino IDE
  • Required Libraries:
    • OneWire.h and DallasTemperature.h for DS18B20
    • DHT.h for AM2302
    • RTClib.h for RTC module
    • SD.h for SD card operations
    • WiFi.h and ThingSpeak.h for cloud connectivity

Getting Started

  1. Clone this repository:

    git clone https://github.com/Lane-Romuald/IoT-irrigation-data-collection-system.git

  2. Open the project in Arduino IDE.

  3. Install the required libraries using the Arduino Library Manager.

  4. Configure your WiFi credentials and ThingSpeak API keys in the source code:

    const char* ssid = "your_wifi_ssid";
const char* password = "your_wifi_password";
unsigned long myChannelNumber = your_channel_number;
const char* myWriteAPIKey = "your_api_key";

  5. Upload the firmware to your ESP32 microcontroller.

  6. Connect the sensors as per the pin configuration specified in the code.
