Introduction: GreenGuard is an advanced greenhouse monitoring and control system designed to optimize the growing conditions for vegetables and other plants using a variety of sensors and automation components. Utilizing an Arduino Uno R3 as the main controller, the system integrates multiple environmental sensors to monitor parameters such as temperature, humidity, soil moisture, light intensity, air quality, and soil pH. This comprehensive system ensures that plants in the greenhouse receive optimal care, resulting in healthier growth and higher yields. The GreenGuard system is equipped with both local and remote communication capabilities, making it accessible and user-friendly for greenhouse managers.

System Overview: The GreenGuard system is a versatile setup, integrating several sensors and actuators to maintain an ideal environment for plant growth. The Arduino Uno R3 serves as the central processing unit, reading data from the connected sensors and controlling actuators based on pre-defined thresholds. This project leverages real-time data monitoring and automated responses to create a self-sustaining greenhouse environment.

Components and Their Functions:

1. Arduino Uno R3 with Cable: The Arduino Uno R3 is the core of the GreenGuard system, acting as the main microcontroller that interfaces with all sensors and actuators. It processes the data collected from the sensors and makes decisions to control the actuators for maintaining optimal greenhouse conditions.

2. DHT22 Digital Temperature and Humidity Sensor Module: This sensor module accurately measures the ambient temperature and humidity levels within the greenhouse. The DHT22 is crucial for ensuring that the temperature and humidity are kept within optimal ranges for vegetable growth. The data from this sensor is used to control the cooling fan and the heating pad.

3. Analog Capacitive Soil Moisture Sensor Module: The soil moisture sensor is responsible for detecting the moisture content in the soil. This information helps the system decide when to activate the submersible water pump and the solenoid valve to irrigate the plants, ensuring they receive the right amount of water for healthy growth.

4. LDR Light Sensor Module: The LDR (Light Dependent Resistor) module measures the intensity of light inside the greenhouse. This data is used to assess whether additional lighting is needed or to adjust the positioning of the plants for optimal sunlight exposure.

5. MQ-135 Gas Sensor: The MQ-135 sensor detects harmful gases such as ammonia and CO2, which can accumulate in the greenhouse. By monitoring air quality, this sensor helps maintain a safe environment for the plants and triggers ventilation if necessary.

6. RS485 Soil pH Sensor PR-3000-TR-PH-N01: This sensor measures the pH levels of the soil, which is crucial for the growth of various vegetables. Soil pH directly affects nutrient availability to plants, and the data from this sensor can help adjust fertilization strategies and soil amendments.

7. 1 Channel 5V Relay Module: The relay module is used to control high-power devices such as the water pump and the solenoid valve. It acts as an interface between the Arduino and these external devices, allowing the microcontroller to switch them on and off as needed.

8. DC 12V Submersible Pump with Hose Pipe (1 Meter): This submersible pump is used for automated irrigation. Based on the soil moisture sensor readings, the pump is activated to deliver water to the plants through the attached hose pipe, ensuring consistent watering.

9. DC-12V Solenoid Valve (1/4 Inch Diameter): The solenoid valve controls the flow of water in the irrigation system. It works in conjunction with the submersible pump to regulate water delivery, preventing over-watering or water wastage.

10. 50mm Cooling Fan: The cooling fan helps regulate the temperature inside the greenhouse. It is activated based on the readings from the DHT22 sensor to provide proper ventilation and prevent overheating, which could stress the plants.

11. USB 5V Heating Heater Pad: This portable heating pad is used to maintain optimal temperatures during colder periods. It is particularly useful for keeping the root zone warm, which is crucial for seed germination and the healthy growth of many vegetable plants.

12. LCD Blue Display 1602: The LCD display provides a real-time visual representation of all sensor data, including temperature, humidity, soil moisture, light intensity, and more. It allows the user to quickly assess the current conditions inside the greenhouse.

13. 4x4 Matrix Array 16 Keys Keypad Module: This keypad module enables user interaction with the system. It can be used to navigate through menus on the LCD, input desired setpoints for various parameters, and manually control actuators when needed.

14. ESP-32 38PIN Development Board with WiFi and Bluetooth: The ESP-32 module adds remote monitoring and control capabilities to the GreenGuard system. With built-in WiFi and Bluetooth, it allows the system to send data to a cloud server or a smartphone app, enabling remote access and control.

15. HC-05 Bluetooth Module: The HC-05 module provides local wireless communication. It allows the user to monitor and control the greenhouse system using a smartphone or tablet within the Bluetooth range, making it convenient to access the system from nearby.

16. 12V 6A 72W Power Adapter: This high-quality power adapter supplies the necessary power to the entire system, including the Arduino, sensors, and actuators. It ensures a stable power supply, which is essential for the reliable operation of all components.

17. 110mm x 60mm 1 Watt 6 Volt Polycrystalline Solar Cell Panel Module: The solar cell panel provides an eco-friendly power source for the GreenGuard system. It can be used to charge a battery, making the system more sustainable and reducing reliance on external power sources.

18. DS3231 Real-Time Clock Module: The DS3231 module provides accurate timekeeping for the system. It allows for scheduled operations, such as timed irrigation or lighting control, ensuring the system operates according to a set schedule.

19. Micro SD Card Adapter v1.1 Module: This module enables data logging, allowing the system to store sensor data on an SD card. This feature is useful for analyzing historical data and understanding the long-term environmental conditions in the greenhouse.

System Functionality: The GreenGuard system continuously monitors the environmental parameters using the connected sensors. When a parameter deviates from the set threshold, the system automatically activates the corresponding actuator to correct the condition. For instance, if the soil moisture level drops below the optimal range, the submersible pump and solenoid valve are activated to irrigate the plants. Similarly, if the temperature rises too high, the cooling fan is turned on to maintain a comfortable environment for the plants.

The system also supports user input through the keypad and provides real-time data display on the LCD screen. The ESP-32 module allows remote monitoring and control via a smartphone app, enabling the user to check the greenhouse conditions and make adjustments from anywhere.

Benefits: The GreenGuard system offers several benefits, including:

1. Automated Monitoring and Control: Reduces the need for manual intervention, allowing for precise control of the greenhouse environment.
2. Remote Access: Provides the ability to monitor and control the system remotely, enhancing convenience.
3. Data Logging: Helps track environmental conditions over time, aiding in better decision-making for plant care.
4. Sustainability: The use of solar power and automated irrigation minimizes resource wastage, making the system eco-friendly.

Conclusion: GreenGuard is a robust and intelligent solution for managing greenhouse conditions. It combines the power of Arduino with various sensors and actuators to create a self-sustaining environment for optimal plant growth. Whether for small-scale hobbyists or larger agricultural operations, GreenGuard provides an efficient way to monitor and control greenhouse conditions, leading to healthier plants and higher yields.
