This Arduino sketch utilizes an ESP8266 microcontroller to read temperature, humidity, and soil moisture values using DHT11 and a soil moisture sensor. The data is sent to the Blynk IoT platform for real-time monitoring. Additionally, the system controls a light based on soil moisture levels and sends notifications about water flow status.

Smart Plant Monitoring System with Blynk

Welcome to the Smart Plant Monitoring System repository! This project utilizes an ESP8266 microcontroller, a DHT11 sensor for temperature and humidity, and a soil moisture sensor. It communicates with the Blynk platform to monitor plant conditions and control a light indicator based on soil moisture levels. The following information will guide you through the project details and code.

Code Overview

  • File: Smart Irrigation & Plant Monitoring.ino.txt

    This Arduino sketch reads temperature and humidity values from the DHT11 sensor, soil moisture from the analog sensor, and controls a light indicator. It communicates with the Blynk app for real-time monitoring and notifications.

Hardware Components

  1. ESP8266 Microcontroller
  2. DHT11 Sensor
  3. Soil Moisture Sensor
  4. LED (Light Indicator)
  5. Resistors
  6. Jumpers and Breadboard

Configuration

  • Blynk Setup:
    • Replace auth with your Blynk authentication token.
    • Replace ssid and pass with your WiFi network credentials.

Pin Configuration

  • DHT11 Sensor:

    • DHTPIN - Data pin connected to D1.

  • Soil Moisture Sensor:

    • A0 - Analog pin connected to the sensor.

  • LED (Light Indicator):

    • Light - Control pin connected to D2.

Usage

  1. Blynk App:

    • Create a Blynk account and set up a new project.
    • Add three Value Display widgets (V1 for humidity, V2 for temperature, V3 for soil moisture) and a Notification widget.

  2. Hardware Setup:

    • Connect the hardware components based on the provided pin configuration.
    • Upload the code to your ESP8266 using the Arduino IDE.

  3. Monitor:

    • Open the Blynk app to monitor real-time temperature, humidity, and soil moisture.
    • The LED light indicates the soil moisture status (on when moisture is low, off when moisture is sufficient).

  4. Notifications:

    • Receive Blynk notifications when soil moisture levels drop below or rise above set thresholds.

Additional Information

  • Temperature and humidity values are read from the DHT11 sensor and displayed on the Blynk app.
  • The soil moisture sensor determines soil moisture levels, and the LED light provides a visual indication.
  • Notifications are sent to alert users when soil moisture conditions require attention.
